Centrifugal Pumps



The Models TC-50 pump is a single or two-stage belt box driven pump. The belt box is mounted directly on the drive motor and drives the pump through a bearing housing which is mounted inside the belt box. The belt box provides an efficient means of significantly increasing the pump speed for higher heads and flows while minimizing maintenance. The pump assembly incorporates a mechanical type shaft seal which is the CFS long-life design. The electric motors supplied as standard are NEMA frame sized, three phase, TEFC, C face type. Motors can also be supplied that meet IP 54, 55, or 56.
