EBARA EVMS(L)(G) Vertical Multistage Pump
The EBARA EVMS(L)(G) series – successor of the EVM series – is a range of vertical multistage centrifugal pumps available in AISI 304 stainless steel (EVMS), AISI 316L stainless steel (EVMSL) or cast iron (EVMSG).
The patented Shurricane® impeller reduces axial thrust by 80%. This protects the motor bearings, allows standard commercial motors to be used on all models – which makes motor replacement faster – and gives high efficiency, with MEI above 0.7 for the most efficient models. The cartridge mechanical seal can be replaced without removing the motor support, and a coupling with spacer makes maintenance of motors above 5.5 kW easier. A low NPSH version (EVMSN) is available on request.
The EVMS-K version is supplied with an integrated E-SPD+ frequency converter, which adjusts the speed to the actual demand of the system.
