S77 submersible multistage centrifugal booster pump

Our S Series submersible multi-stage high pressure booster pumps come in a variety of stagings. The Stainless Steel pump line is available in 304ss, 316ss and 316ss electro polished wetted parts. We boast a modular design that encompasses the main assemblies of the pump end allowing field repair when necessary. We also offer bearings in different configurations to accommodate various thrust loads, and a mechanical seal selection which allows incoming pressure to range from 10psi to 800psi. We test every booster pump throughout the specific hydraulic range of its series along with vibration analysis to assure a long and trouble-free life. The S77 generates pressures up to 820 psig and flows from 60 to 220 gpm.

All stainless steel construction
