Sanwa Hydrotech Corporation develops, manufactures and sells process pumps including metallic seal-less magnet drive pumps, multi functional pumps for slurry application.

SIP (Sterilizing In Place)
Magnet pump used for circulating hot water

Outline

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.

Advantages of Sanwa stainless steel magnet drive pumps in the sterilization process.

	SANWA stainless steel Magnet drive pump		Seal pump
Safety	No shaft seal Completely leak-fee	Leak	Mechanical seal／ Gland packing Cannot prevent leakage perfectly
Energy saving	MAGPAC series Up to 280˚C without cooling water	Utility	Cooling water is required on shat seal for high temperature (100˚C and over)
Total cost reduction	Periodic checks and repair are not needed for extended period of time. (No consumables parts, Spare parts are not necessary)	Maintenance	Periodic checks and repairs are needed. Consumable spare parts are needed such as gasket and mechanical seal
	Eliminates burden on the field staff	Downtime	Specialized engineers are necessary Periodic maintenance is required. Burden on field staff is heavy
