Food processingDairy industryBeerBeverageResist to high pressureCooling water is not necessary up to 280˚C


Introduced products MP
Temperature of liquid high temperature water (100 to 150℃)
Application Magnet drive pump SIP

Fresh milk from a farm becomes processed milk after several processes including sterilization. During the high-temperature sterilization process using a heat exchanger, the temperature of hot water reaches up to 150℃ with the pressure of 0.4 MPaG.
Sanwa's stainless steel magnet drive pumps (MAGPAC series) for this system offer various advantage compared with seal pumps for its feature leak-free, high temperautre resistant and high pressure resistant.
