HTW 80

HTW 80

1 1/2 x 1 1/4 End Suction Centrifugal Hot Water Pump

The HTW 80 is a patented, unique centrifugal pump specifically designed for high temperature process manufacturing applications using hot water, ethylene glycol, propylene glycol and triethylene glycol.  The Tempuflo HTW Series utilizes an isolated seal chamber, which is effectively cooled by both a cooling loop (heat exchanger) and by a fan clamp which couples the unit to the shaft of a standard NEMA C Face frame motor.

The isolator technology combined with the heat exchanger allows the seal cavity to reach a maximum and seal chamber temperature of 170°F (77°C) while the process temperature is at 400°F (204°C). This lower seal temperature greatly increases seal life, which means less down time for the end user.

Discharge port location can be provided as either Horizontal or Vertical position.
