TC-34.2

TC 34.2 is a fully Submerged pump and permanent magnet motor assembly. It allows for quick response in pumping and minimal product loss.The active thrust balancing system provides greater stability. And, offers longer life with lower maintenance requirements. Its VFD compatibility allows for a broad range of operation. The construction is all aluminum and it is driven by a permanent magnet motor. TC34.2 was specially designed with a “Submerged” motor installed in a vacuum jacketed suction vessel “sump”.

Features & Benefits

  • Active thrust balancing system for extended bearing life
  • High efficiency hydraulics with extremely low NPSHR inducer
  • Light weight & compact
  • Available in sump & in-tank designs
  • Special design VFD drive provides operation point control over the entire pump operating range
  • Quick electrical disconnect for ease of maintenance
