Continue to inject grout using the new location. Once the jack screws are removed, fill the resultant voids with grout or liquid epoxy. © Copyright Cahaba Media Group, Inc. All Rights Reserved. Access holes for grouting should be provided in the skid floor plate by the OEM or packager. When removing the laitance, do not use a jackhammer, which may crack the concrete. JavaScript is disabled for your browser. Elsey may be reached at jim@summitpump.com. Design procedure of Grout At the time of designing, proper consideration should be given on the strength and thickness of the grout. Is it Worth It?” TAMU Paper 2004 Pump Symposium, Roger L. Jones, Charles A. Lickteig, Jean J. Zoppe, “The Road to Reliable Pumps,” TAMU Paper 2007 Pump Symposium, Todd R. Monroe, “Pump Users Handbook, Life Extension,” Heinz P. Block & Allan R. Budris. Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. You can sandblast the underside and then install the base immediately before corrosion occurs (less than eight hours in an ideal ambient). Base Plate Tightening after Base Level on Pads Achieved. If required, the base frame bottom should be painted with epoxy grout primer. Access holes are very important when trying to flow any type of grout 10’ to 12’ across and 20’ to 30’ down the length of the foundation. Installation • Level pump, base and motor and ensure the area is free of soft foot conditions. Keep in mind that when pouring the grout into the forms, the displaced air needs somewhere to go, and that transverse base members and braces can sometimes prevent the proper installation and venting. Never let rain fall on equipment during this process. Be aware that during the curing process, the grout can actually pull the base out of level as it shrinks. On the other hand, pre-filled or pre-grouted baseplates arrive at site already flat and aligned. Base frame is to be leveled on leveling plate or using jack screws to 0.02inch/ft. (if specified) for all horizontal pump baseplates. Field machining of the base after completing the critical grouting process is difficult and expensive. Execution of the leveling and grouting uses known techniques, but with a new twist, and are designed to shorten the pump installation and alignment time by application of a “one pour” grout procedure. During the injection, cement slurry (usually prepared at some distance away from the drill holes) is normally transferred through pipes into the drill holes by an applied pumping pressure. Do not allow the grout to come in contact with the anchor bolts. Only a fraction of the API pump baseplates were distorted but nearly all the ASME bases were. A conventionally grouted base plate usually requires two pours, plus additional time and manhours spent for repair-filling of any voids once the grout has cured. Tighten the foundation anchor bolts evenly and double-check the level. Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. Jim Elsey is a mechanical engineer who has focused on rotating equipment design and applications for the military and several large original equipment manufacturers for 43 years in most industrial markets around the world. Before considering the most prevalent pump base plate installation options, we need to know more about how pump sets are typically shipped to the purchaser or installation site. 6. Some companies will buy the least expensive baseplate and then lay it on the floor/ground with no further action other than to pipe up the pump and connect the electricity to the motor. As per AISC Design Guide 1, the compressive strength of the grout should be minimum twice the footing/pedestal ones whereas as per ACI 351.1R-99, the compressive strength of the grout should vary from 5 to 55 MPa (5000 psi to 8000 psi). For epoxy grouts, mix the liquid first (resin and catalyst) and then add the aggregate to the liquid mix—not the other way around. Alternatively, for large grouting areas, a grout lance is placed through the gap to the other side and withdrawn slowly as pumping proceeds. A common tip is to fill the sleeves with dry sand to prevent the grout from entering that area. • Provide at least 10 diameters of straight pipe to the pump’s suction inlet. Check with the manufacturer, but in most cases 4 mils (dry) is the proper amount. a. As an example, a 100-hp pump/driver set is purchased and the next step is installation. Many people do not properly prepare the base’s underside surface or they apply too much epoxy paint. using vertical and horizontal jack bolts. Additionally, recommendations and specifications focus on ensuring that the baseplate is properly grouted (grouting bonds the base to the foundation). Methods used by the author to level and epoxy grout pump baseplates. the grout has moved from the 4"-diameter (min.) be spillage. 2. Anyone with pumps that operate in this manner for more than three years with no downtime for bearings, mechanical seals or couplings also has luck on their side. This is a highly recommended step. Chances are the pump is lower horsepower, and the service is ambient temperature and at low-duty hours. A proper baseplate installation will maintain that crucial alignment—and pay off for decades with reduced maintenance costs. Base Grouting Process ... for the base grouting process. Place some tension on the anchor bolts relative to the base when grouting to keep the base from floating. Pump Baseplate Installation And Grouting. By sloping out from the base plate you can get a little more bearing area on your pier. Learn the basics of wear components and their role in system operation in this white paper. This pour technique requires good flow characteristics from the grout material, and is typically only used for epoxy grout applications. used for the leveling pads to be utilized under the pump baseplate leveling jackscrews. Another approach is applying the proper epoxy paint to the underside as a surface to which the grout can bond. Heinz P. Bloch, in Petrochemical Machinery Insights, 2017. I prefer the one-pour process, especially if using epoxy grout; it takes a little more preparation time because of the more sophisticated forms, but it will yield excellent results if done correctly. pour hole to the point farthest away. Move to the nearest hole where grout has appeared. The loads from pump pedestal are transferred to baseplate and finally to grout. The end user should specify these when purchasing. I acquiesce that the smaller the pump and consequential horsepower, the need for the expensive installation (foundation, baseplate and grouting) is diminished. The reasons for the use of epoxy grout in place of cheaper cementitious grout will be covered along with special baseplate preparations. Do Not saturate concrete when using Conbextra epoxy resin grouts! If using leveling jack screws, coat them with something (grease) to facilitate their removal. Base plate grouting operations traditionally utilize cement grout. This technique allowed for more precise results. However, many industries are turning towards epoxy grout due to its rapid strength development and superior material properties. Many believe it is to hold the base to the foundation, but the purpose is to pull the foundation, the grout and baseplate together to form one monolithic mass. Laitance refers to the thin, flaky layer of hardened yet weak hydrated cement and fine sand on the top surface of concrete, usually from too much water or overworking the surface (for example, resulting from excess trowel work). 20.6 Effect of pressure grouting in unsaturated condition. Some common goals clients report to me include having a pump that operates reliably for a long time combined with an inexpensive installation. The grout forms need to be strong and liquid tight (do not hesitate to caulk the joints). Small metal plates, preferably stainless steel, can be placed under the jack screw’s nose. High strength, rapid setting and free-flowing grouts for all types of support applications in civil engineering, general construction and industrial applications. Some situations such as grouting under a wall panel or small base plate for example, will favour installation by dry packing or trowelling in the grout. The specific sequence is paramount. Mounting holes for anchor bolts in the bases shall be drilled and not burned out and they shall not be open slots. In Hong Kong, soil nails are generally grouted under gravity. Typically it is best to pour from one side to let the air escape from the other. A good foundation has been designed and it is time to grout the base to the foundation. The following blog outlines the importance of grouting base plates, how to go about the grouting process, and common issues that may arise during the process. • Offset pump and motor shaft/coupling hub keyways by 180°. Larger baseplates typically will best be grouted using a flowable consistency grout and formwork. In general, process pump manufacturers are asked to provide pumps as a “set” or assembled package comprising pump, driver and base plate (see figure 1). c. Remove ports or fittings and check to assure Many end users shy away from pre-grouted pump bases or poly pump bases because of their higher initial cost, but anyone wanting a proper installation at an overall and long-term value should consider these alternative choices, especially in the National Electrical Manufacturers Association (NEMA) motor size ranges of 250 horsepower (hp) and below. I have added (drilled) plenty of vent holes in the base to allow for the venting process. Did you remove the pump and driver? Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. This method statement describes the step by step procedure for grouting of machine bases and base ... entire void under the base plate has been filled. A common practice is to use two to three layers of paste wax. Slowly add powder to a pre-measured amount of water, ensure Wait longer if moisture is visible on the underside of the plastic the next day. Effectively communicating the specifications and procedures to the contractor increases the chance for success. Many jobs lost will shift toward renewable energy. Doing more with less is a necessity going forward while navigating business during a pandemic. These plates are commonly referred to as “pucks.”. Instead, use a small, light-duty pneumatic hammer with a sharp point tip, sometimes referred to as “bush hammering.”. The wooden grout form now requires a top plate that forms a liquid tight seal against the bottom flange of the base plate. Pour the grout from a head box that is positioned at an elevation higher than the baseplate to provide a static head for the grout to flow. The Grout The forces and vibrations present in our rotating equipment must be absorbed by On exterior base plates the grout keeps water from sitting in the plate/pier joint. Once the alignment target is achieved, there will be a gap between the underside of the component foot and the Mounting Plate/Base Plate or Chock Plate surface. “Grouting of Small Pump Baseplates? More importantly, the base provides a path for the transmission of vibrations, nozzle loads and piping forces to the foundation and into the ground. Conventional grouting methods for nonfilled pump baseplates are, by their very nature, labor- and time-intensive. All bases for horizontal pumps shall be equipped with jackscrews for positioning and leveling the base prior to grouting. Some features of this site may not work without it. Not really compelling arguments for sure. Consider these questions: When was the last time you turned the baseplate over and prepared the surface to be grouted? Use a protective sleeve/tube with some clearance to allow for tolerances and ease of handling. Let’s go back a minute…the driver is aligned to the driven component, Pump, Compressor, Fan, etc. To prevent stress and distortion of the equipment, all surfaces in the same plane must be within 0.002″ overall. Start injection at one end of void and pump until grout is discharged from adjacent tap holes. 3. Expansion joints are to be made of 25 mm (1 in) closed polyethylene cell foam (or equal) and placed at 1.2 to 1.8 m (2-6 ft) intervals, perpendicular to the centerline of the base plate, in accordance with API Recommended Practice 686. Here are some tips for the grouting process. Continue this process until all air is vented and all voids filled. the pump mounted on the base, but not centered on the base hold ... sequence of events for the first part of the process—foundation, leveling, grouting. They also serve as a "tell tale" to let you know that. Along with the concrete grouting, the foundation bolts secure the baseplate firmly to ensure vibration free pump performance. Find out which technologies work best to keep centrifugal pumps from causing downtime in critical industrial processes. If installing a base on a new or existing concrete foundation, be sure to chip away the laitance at least one-half inch or, in the case of working an old foundation, until reaching stable concrete or aggregate. The grout allows a little play in the as-cast foundation height as gives you space for leveling. Pump baseplate installation and grouting techniques covered are applicable to any turbomachinery baseplate, bed rail, or skid installation. b. Prudence suggests you have 10 percent more grout than the form volume—and I guarantee there will f. Depending on the size of the application, it may be necessary to “rod” the grout with a thick chain to help the grout flow. It is acceptable to pump the grout in place with different and specific appliances for that purpose. All mounting studs shall be Type 316 stainless steel. The workability or consistency of the grout needs to match the requirements of the application. Test for moisture by using duct tape to secure a 2- or 3-foot-square piece of plastic over the foundation overnight. Learn how early adopters are benefitting from emerging technology as well as the impact COVID-19 has had on water management. It was easy if the base manufacturer designed for the use of jack screws, but even when that was not the case, they were easy to adapt and install in the field. Wan-Huan Zhou, in Ground Improvement Case Histories, 2015. When I started in the business, we would use sets of wood or metal shims to level the base prior to grouting, leaving the shims in place. 4.4.2Apparatus—The apparatus generally consists of a stiff steel plate or channel supported on shims a few inches above a rigid concrete base. They also informed us that they do not back off leveling nuts below the base plates during the grouting process. Most designs require the installation of anchor bolts in the foundation that will run up and through penetrations on the baseplate. In the past, many installations used cementatious grout, but most companies in the last 20 to 30 years have elected to use epoxy grouts. In the case of a new foundation, this depends on ambient conditions and on the concrete mix that was used (a five-bag mix can take as long as 28 days while a seven-bag mix may cure in a week). Missed your issue of Pumps & Systems because you are not at work? Experience has taught me it is prudent to remove the shims after the process because as the shims corrode or rot they will create other issues with the foundation-to-grout joint. a Process Industries Practices (PIP) type baseplate. When the baseplate is level, check that all support wedges or shims are in full contact with the foundation and baseplate. Never use a vibratory device unless specifically directed by the grout manufacturer. These vent holes are absolutely necessary to expel air as the cavity fills with grout. Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University. The grouting helps to reduce the vibration, deflection and noise of the whole pumping unit. A Professional’s Guide on Grouting and Concrete Repair PREFACE This handbook, the first of its kind in the industry, was originally published by FIVE STAR PRODUCTS, INC. in 1981 as an aid to owners, engineers, architects, specifiers and contractors involved in the selection, specification and use of nonshrink grouts and concrete repair materials. They will have prepared the surface solely to prevent corrosion in the transit and storage stages. The plate is commonly 1 by (2 or 3) ft [300 by (600 or 900) mm] with the grout flowing in the long direction. It may be necessary to remove the protective paint supplied by the manufacturer. To read other articles in the 'Common Pumping Mistakes' column, go here. Installation Procedures - Epoxy Grout 03 63 00 epoxy GroutinG 3-433 Construction expansion Joints 1. The plate is held down by bolts an- chored in the concrete. This tip reminds me of my submarine days when the specific instructions were to shut the hatch and then dive the boat. Base Plate Grouting. Detailed and timely information enables performance to reach new levels. Epoxy grouts yield superior results in most cases, while cementatious grout is less expensive. Consider using flow conditioning technology as an alternative. Do not use oil because it can react with the grout substrate. He is the general manager for Summit Pump Inc. and the principal of MaDDog Pump Consultants LLC. If the paint is too thick, the epoxy grout will pull the paint off of the metal, a process known as delamination. If using shims, be sure to apply a coating (such as light grease) of some sort to ease removal. You will not have enough grout if you simply allow for the volume of the form. Grout manufacturers will advise the proper surface preparations and paint for their grout. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. All grouting should be done using established procedures and recommendations of ACI for placing and curing concrete Temperature Restrictions: Grouts generally work best at 50-80°F. Their structural integrity is also better since no grout holes are necessary. Figure 8. In fact in the grouting checklist, Chapter 5, Section 4.1 - Mounting Plate Design Verification, stainless steel is indicated as material for the leveling pads. If the site is too hot or cold, steps must be taken to change or control the situation, such as temporary insulated shelters or shade from the sun and heat. Execution of the leveling and grouting uses known techniques, but with a new twist, and are designed to shorten the pump installation and alignment time by application of a “one pour” grout procedure. Curing time for grout, especially epoxy grout, depends on the ambient temperature. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Mixing Use a slow speed drill (appx 500rpm) with Mixer Paddle MR3, for large quantities a shear vane mixer may be used. The sand can be topped off with caulking or tape. Continue to check for level during the curing process. Elsey is an active member of the American Society of Mechanical Engineers, the National Association of Corrosion Engineers and the American Society for Metals. I would argue that it is rare to accomplish both on the same job. Hydraulic Institute on examining altitude, temperature and more when selecting a wastewater pump. Without sufficient investigation—that is, with a grotesquely inaccurate, low estimate of cost to field machine—the pump manufacturer gave instructions to field machine the distorted Without the plate to provide initial grout distribution across the entire shaft base, staged grouting of ... measurements of grout pressure at the pump, and strain gages at the shaft base (1 in = 25 mm, and 1 kip = 4.4 kN). Managing Pump Station Assets for Lowest TCO & Maximum Effectiveness, Pumping Systems: Essential Now & in the New Year, Centrifugal Pumps: The Condition Monitoring Comparison Guide, Water@Work: Emerging Technology & The 2020 Impact, Replacing Metallic Wear Components with Composites in Centrifugal Pumps, In-depth articles on pump industry issues, Expert insights into important topics in the field. The purpose of any baseplate is to provide level, coplanar surfaces to mount the pump and driver, allowing for a proper and precise alignment between the two. Pour the grout from a head box that is positioned at an elevation higher than the baseplate to provide a static head for the grout to flow. We consider that Key regulations are back on the table under a new presidential administration. However in Figure G-1 of Chapter 5, carbon steel is indicated the material. By comparison, the forms used to pour a patio or driveway are probably not strong enough for this application. A peristaltic pump is used for resin grouts and a diaphragm or worm pump for cement grouts. Cut keys to one-half the keyway length. The concrete foundation must be adequately cured before installing and grouting the base. This article does not address stilted pump bases. Introduction. Begin the grouting process immediately after completion of the saturation process. The equipment (pump and driver) should be removed from the baseplate during the grouting process. A cast iron, Process Industry Practices (PIP) or structural steel base also has been purchased. Coat forms with something that will not adhere to the grout. Utilizing a pregrouted baseplate with conventional grouting methods helps to minimize some of the cost, but the last pour still requires a full grout crew, skilled carpentry work, and good logistics. If the base is not designed or installed properly, the investment in the alignment process will be lost in the first moments the pump operates. Add a minimum of four ½"-diameter vent holes in each pump cavity compartment. Page 1 www.neoflux.inof 3 Pumpletter November 19, 2011 Centrifugal Pump Grouting: SUBJECT: Attaching the pump and motor base plate to the foundation. A range of materials suitable for pumping or traditional methods of placement for the void-free grouting of gaps of just 0.1mm to 140mm and above. After some time in the field, I learned to use leveling jack screws in lieu of shims. Prior to the grouting process, decide whether to use the two-pour or one-pour method. Manufacturers often encourage their customers to have a foundation with a mass three to five times the mass of the pump, driver and baseplate combined—even more if the pump is a positive displacement design, especially reciprocating pumps.
