Centrifugal Pumps



TC 34.2 is a fully Submerged pump and permanent magnet motor assembly. It allows for a quick response in pumping and minimal product loss. The active thrust balancing system provides greater stability and offers a longer life with lower maintenance requirements. Its VFD compatibility allows for a broad range of operations. 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”.
