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. Before removing the equipment, make sure it can be aligned and the base is flat and coplanar. Do not use oil because it can react with the grout substrate. This technique allowed for more precise results. The plate is held down by bolts an- chored in the concrete. Wan-Huan Zhou, in Ground Improvement Case Histories, 2015. Use a protective sleeve/tube with some clearance to allow for tolerances and ease of handling. 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. • Offset pump and motor shaft/coupling hub keyways by 180°. Elsey is an active member of the American Society of Mechanical Engineers, the National Association of Corrosion Engineers and the American Society for Metals. Missed your issue of Pumps & Systems because you are not at work? Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. Try to avoid pushing or rodding the grout into place because it creates air entrainment and voids. Continue this process until all air is vented and all voids filled. Base Grouting Process ... for the base grouting process. As an example, a 100-hp pump/driver set is purchased and the next step is installation. 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. 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. A good foundation has been designed and it is time to grout the base to the foundation. He is the general manager for Summit Pump Inc. and the principal of MaDDog Pump Consultants LLC. a. 20.6 Effect of pressure grouting in unsaturated condition. They will have prepared the surface solely to prevent corrosion in the transit and storage stages. 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. Not really compelling arguments for sure. 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. Hydraulic Institute on examining altitude, temperature and more when selecting a wastewater pump. Detailed and timely information enables performance to reach new levels. 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. Most designs require the installation of anchor bolts in the foundation that will run up and through penetrations on the baseplate. 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. 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. the grout has moved from the 4"-diameter (min.) Epoxy grouts yield superior results in most cases, while cementatious grout is less expensive. Some common goals clients report to me include having a pump that operates reliably for a long time combined with an inexpensive installation. In the past, many installations used cementatious grout, but most companies in the last 20 to 30 years have elected to use epoxy grouts. be spillage. (if specified) for all horizontal pump baseplates. For epoxy grouts, mix the liquid first (resin and catalyst) and then add the aggregate to the liquid mix—not the other way around. Continue to inject grout using the new location. 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. If using shims, be sure to apply a coating (such as light grease) of some sort to ease removal. Only a fraction of the API pump baseplates were distorted but nearly all the ASME bases were. The sand can be topped off with caulking or tape. 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. Never let rain fall on equipment during this process. On the other hand, pre-filled or pre-grouted baseplates arrive at site already flat and aligned. pour hole to the point farthest away. They also serve as a "tell tale" to let you know that. Learn the basics of wear components and their role in system operation in this white paper. Test for moisture by using duct tape to secure a 2- or 3-foot-square piece of plastic over the foundation overnight. They also informed us that they do not back off leveling nuts below the base plates during the grouting process. This pour technique requires good flow characteristics from the grout material, and is typically only used for epoxy grout applications. Base plate grouting operations traditionally utilize cement grout. You can sandblast the underside and then install the base immediately before corrosion occurs (less than eight hours in an ideal ambient). 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. 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. Additionally, recommendations and specifications focus on ensuring that the baseplate is properly grouted (grouting bonds the base to the foundation). 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. The grouting helps to reduce the vibration, deflection and noise of the whole pumping unit. 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. Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. Their structural integrity is also better since no grout holes are necessary. Continue to check for level during the curing process. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Typically it is best to pour from one side to let the air escape from the other. Access holes for grouting should be provided in the skid floor plate by the OEM or packager. Prior to the grouting process, decide whether to use the two-pour or one-pour method. Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University. Wait longer if moisture is visible on the underside of the plastic the next day. Another approach is applying the proper epoxy paint to the underside as a surface to which the grout can bond. © Copyright Cahaba Media Group, Inc. All Rights Reserved. Be aware that during the curing process, the grout can actually pull the base out of level as it shrinks. I would argue that it is rare to accomplish both on the same job. Let’s go back a minute…the driver is aligned to the driven component, Pump, Compressor, Fan, etc. 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. Base Plate Grouting. Effectively communicating the specifications and procedures to the contractor increases the chance for success. Conventional grouting methods for nonfilled pump baseplates are, by their very nature, labor- and time-intensive.
