The Wilo Economy MHI 203 (1~230 V, EPDM) is a single phase high-pressure multistage centrifugal pump with a 0.55kW motor. The Wilo Economy MHI range are horizontal multistage pumps which have a wide range of uses including water pressure boosting, circulation in cooling systems and washing or sprinkler systems. WRAS approval means these pumps are rated for use with drinking water. They are available with the wetted parts in either AISI 304 or the higher grade AISI 316 stainless steel, which offers greater protection against corrosion. Both single phase and three phase versions are available.
