The IDEAL Pump Coupling System for Today's Foam Manufacturers

MHR's line of Magnetic Drive Couplers will couple virtually any chemical metering pump used in high or low pressure RIM. The conversion is quick and simple. MHR looks at the motor/torque requirement of the application, and then calculates the magnets required to run the application without slippage. MHR's rigid alignment system integrates pump and motor together as one single unit. This system provides for the chemicals to be completely self-contained within a stainless steel housing, with shaft seals being eliminated altogether. No more chemical leakage!

  • Eliminates leaks common to any polyurethane systems!
  • No more shaft seals to worry about-shaft seal is not required!
  • Down time from changing seals, virtually eliminates!
  • Variety of magnet sizes offers strong and dependable coupling systems.
  • Rigid alignment provides no more needs to shim for alignment.
  • Re-circulation ports for cooling purposes are a standard feature on every unit.
