EBARA’s Model EVMSU vertical multistage pump features a newly designed “Shurricane™” impeller that reduces the axial thrust load with higher pump efficiency created by the innovative hydraulic design of the impeller shrouds. The Shurricane™ impeller is designed to deliver optimum hydraulic efficiency and significantly reduce axial thrust loads so that standard C face motors may be used with no special (thrust) bearing requirements. The EVMSU also features cartridge type mechanical seals (single inside unbalanced or balanced as required). To allow for mechanical seal replacement without removal of the motor, a spacer coupling is provided on units with motor horsepower of 7-1/2 and above.

With hydraulic coverage to 390 GPM and 930 feet TDH, the EBARA model EVMSU is designed for booster, water purification, and hot water applications.

Note: Models EVMSU/EVMSUL 1-20 and EVMUG/EVMUL 32-64 certified to NSF/ANSI 61 & 372.
