Allweiler NTT Thermal Transfer Pump

NTT Series Centrifugal Pump

The Allweiler®* NTT series Centrifugal pump for heat transfer oils is an ideal solution for the handling of organic heat-transfer oils in heat-transfer plants from 0-6400 GPM at temperatures up to 660°F up to 475 feet of head. The NTT's unique design eliminates the need for cooling due to its self-cooling design characteristics over any operational temperature range during operation.

The NTT series advantages for the pumping of heat-transfer oils are numerous, but here are just a few:

  • Heavy Duty Bearing Maintenance free groove ball bearings are utilized. Compared to sleeve bearing, ball bearings will absorb radial forces and temperature changes much better.
  • Easy Maintenance Back pull out design allows bearing housing and rotating element removal without disturbing discharge and suction plumbing.
  • Quiet operation and Long service life The Allweiler®* NTT series of thermal oil pumps are designed to be one of the quietist and long operability centrifugal pumps in operation today.
