CombiTherm Plus – Centrifugal Pumps for Thermal Oil or Hot Water Applications


These heavy duty, centerline mounted pumps are designed to handle thermal fluids including mineral or synthetic heat transfer oil up to 660°F at 360 PSI and hot water or glycol based thermal fluids up to 400° F at 450 PSI without the need for expensive auxiliary cooling or shaft sealing systems. The optimized air cooling system ensures that the seal temperature does not exceed 220° F, even at process temperatures of up to 660° F resulting in long seal life and minimal down time. 


  • Ports ASME B16.5 300lbs  - Standard heavy duty flanges
  • Front End Design  - Wear ring in pump casing, Anti vortex vane in suction port, Chambered graphite gasket, Back vanes and labyrinth ring prevent particles from entering journal bearing and shaft sealing area
  • Centerline Mounted – Allows thermal expansion without affecting shaft alignment giving longer life to bearings and seals
  • Optimized Cooling Fan/Cooling Fins – Lowers shaft sealing temperature for increased bearing and seal life, no auxiliary cooling required
  • Journal Bearing Cartridge – Hard-carbon bearing bushing pumped liquid lubricated
  • Bearing Arrangement – Double row angular contact bearings, Bearing area sealed with contact less seals for no wear on the shaft, Bearing protected in case of seal failure
