Appointment
High pressure pumps WILO MHI are used for pumping drinking water, cold and hot water in heat and water supply systems, condensate, a mixture of water with glycol (up to 40% glycol in the mixture), as well as other media free of mineral fats, abrasive and long-fibred inclusions.
Application of high pressure pumps MHI: installation of water supply and raising pressure, boiler feed, industrial circulation systems, water cooling circuits, fire extinguishing systems, as well as washing and irrigation installations.

Explanations for inlet pressure: maximum pressure on inlet is calculated as the maximum operating pressure of the system minus the maximum pressure generated by the pump at Q=0.
Explanations for the materials used: steel 1.4301 complies with AISI 304, steel 1.4404 corresponds to AISI 316L.
