End pump seal maintenance and chemical leaks with wear-free magnetic couplings.

Magnetic couplings improve the reliability, safety and efficiency of polyurethane processing by eliminating the need for drive shaft seals in the metering pump.

Mechanical shaft seals, which separate the drive motor from chemicals in the metering pump, deteriorate over time and cause leaks. Magnetic couplings enclose the drive shaft in an airtight housing. There are no mechanical seals. Permanent magnets in the coupling’s nested rotor system transmit the high drive torque through the coupling enclosure, providing wear-free operation and overload protection.

The airtight, leak-free design makes magnetic couplings an ideal technology for meeting environmental and safety requirements associated with processing the more toxic, aggressive or flammable components used in some polyurethane foam applications.
