Pumps And Dewatering Equipment: Equipment Spotlight
Pumps and dewatering equipment from Xylem, Holland Pump, Grindex Pumps, Atlas Copco, Rain for Rent, Gorman-Rupp, Thompson Pump & Mfg. and Griffin Pump.
Xylem
A new powerful and compact Godwin Vac-Prime is a highly efficient, automatic, self-priming dewatering solution ideally suited to well-pointing. As a result of its compact size, Xylem’s Godwin Vac-Prime is easy to move and transport. It does not require specialist transport and with its lifting frame, fork pockets and optional wheels, it needs minimal on-site equipment. The speed of air evacuation that it delivers is due to a combination of the highly efficient vacuum pump and the fast-priming system. Vac-Prime 4-inch and 6-inch models can manage heads of 11-25 meters, flows of 100-374 m³/h and solids handling of 45-75mm. 914.323.5700, xyleminc.com
Holland Pump
Holland Pump Standby Lift Stations provide 100 percent redundancy and double protection from both electrical failures and mechanical failures. Holland Pump has models available from 3 to 18 inches in capacities from 400 to 40,000 gpm with solids up to 6 inches and can be powered with diesel or natural gas engines. Holland’s Prime 3 priming system has suction lift capability to 28 feet and has 50 CFM priming power. The electronic monitoring system is a micro-processor based single engine controller that supports both mechanical and electronic engines and permits the user to readily and remotely instruct the control system to do a broad range of activities including auto start/stop, and communicates through an RS485 and RS432 for Modbus RTU. 800.451.0796, hollandpump.com
Grindex Pumps
Grindex Pumps offers a complete line of highly efficient and reliable submersible pumps for drainage and sludge applications ranging from 0.6 to 140 horsepower. These pumps boast solids handling capability of up to 3.2 inch, capacities of up to 375 feet and 5,000 GPM. Stainless steel options are available. Air cooling valves permit pumps to run dry without damage. With SMART motor protection Grindex pumps will not run backwards, will not single phase and will not overheat. 708.781.2135, grindex.com/us
Atlas Copco
WEDA submersible pumps are available in nine different models, including a sludge pump, and are available to handle applications of any size. The cost-effective, unique sealing system allows the user to change seals, impellers and other parts in just minutes. The replaceable cartridge seals include the necessary bearings, lubricant and other components. The modular design creates a lightweight product with fewer parts and minimal service hours for lower total cost. Machined slots also make separation of the various parts of each pump easier. Since the stainless steel bolts and nuts are a uniform size, only one tool is needed for maintenance. Other WEDA pump features include built-in starter and motor protection, optional automatic level control, adjustable wear-resistant rubber diffusers, and hardened high chrome impellers. 800.732.6762, atlascopco.us
Rain for Rent

With a footprint of 170 square feet, smaller than some lower volume pumps, the DV600c can be easily transported by truck. A 430 gallon integral fuel cell allows for 22 hour run time. 800.742.7246, rainforrent.com
Gorman-Rupp
The Gorman-Rupp line of Prime Aire Plus pumps employs the same venturi/compressor priming system as the Prime Aire line.
