Use of magnet pump for circulation system of hot water and SIP (Sterilizing In Place)
In addition to its feature of complete leak-free, the magnet pump brings various advantages compared with ordinary seal pumps, including excellent resistance to high temperatures and high pressures.

| Introduced Products | MP |
|---|---|
| Temperature of liquid | high temperature water (100 to 150˚F) |
| 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˚F 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 sealCompletely leak-fee | Leak | Mechanical seal／Gland packingCannot prevent leakage perfectly |
| Energy saving | MAGPAC seriesUp 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 |
