Vertical high pressure pumps from stainl. steel - SIGMIA Trading ENG

New vertical multistage centrifugal pumps which come in various versions: cast iron (EVMG),AISI 304 stainless steel (EVM), AISI 316 stainless steel (EVML) and WRAS-approved (EVMW). Reliable, quiet and easy to maintain. They come with different numbers of stages and in a different sizes to meet individual capacity and head requirements. Suitable for municipal, Industrial and agricultural applications e.g. Fire fighting systems, pressure boosting (WRAS approved) water treatment plants, irrigation, hot and cold water movement for heating systems, cooling and airconditioners, especially suitable for boiler feed due to their sturdy construction.
