cast iron, AISI 304, AISI 316
Vertical multistage centrifugal electric pumps available in various versions: cast iron (EVMG), AISI 304 stainless steel (EVM), AISI 316 stainless steel (EVML). Suitable for civil, industrial, agricultural and fire-fighting pressure boosting systems, primary water treatment plants, reverse osmosis, seepage, etc., moving moderately aggressive fluids, boiler loading, washing, heating systems and air-conditioning. Reliable, strong, silent and easy to service. The EVM pumps can be coupled with standard EIC motors. They offer state-of-the-art technical solutions. The EVM vertical multistage pumps (hydraulic parts) are in compliance with the 94/9/CE Directive on ATEX products (they belong to Group II, Category 2). Oval counter-flanges, “N” version, already included. Round counter-flanges, “F” version, as accessories.
Version with WRAS approval (EVMW 3-5-10-18). ATEX version for complete electric pump. Also available with efficiency 1 motor.
