New vertical multistage centrifugal pumps 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 different sizes to meet individual capacity and head requirements. Suitable for industrial and agricultural applications, fire fighting systems, pressure boosting (WRAS approved), water treatment plants, irrigation, hot and cold water movement for heating systems, cooling and air conditioners, especially suitable for boiler feed due to their sturdy construction. All the new EVM pumps can be coupled with standard IEC motors. The new vertical multistage pumps according to 94/9/EC directive on ATEX equipment (belonging to Group II, Category 2).
