Cryogenic Pumps

Centrifugal Pump
AC/TC30

The AC/TC-30 pumps are single-stage or multiple-stage, close coupled pumps and are mounted directly on the drive motor. Our close coupled type pump assembly has fewer moving parts than hydraulic, gearbox, or belt box driven pumps. As a result, they have inherently higher efficiencies and lower maintenance.  Also, the pump features either aluminum housings or all bronze construction with pump housings, impeller, and inducer.  Mechanical, gas riding, and labyrinth style shaft seals are available, among others.

Features & Benefits

  • Close coupled design provides operations at high efficiencies, fewer moving parts & lower maintenance costs
  • Minimum recirculation wear rings reduce maintenance requirements and improve efficiencies
  • Shaft seal design is state-of-the-art and prolongs life without leakage (mechanical, gas-riding or labyrinth)
  • VFD compatibility allows for multiple operating speeds
