HT Series

Overview

Nikkiso SGM - series canned motor pumps are centrifugal pumps which, due to their construction are hermetically encapsulated. The shaft seal usually required on centrifugal pumps is not necessary. The pumps are driven by integrated canned motors. Space requirements and noise emissions are much lower than those of conventional centrifugal pumps. The pumps are equipped with Nikkiso's unique E-Monitor.

The HT type is designed for hot fluid applications up to 400 deg C. The pump and the motor are separated by a heat barrier, the motor is additionally equipped with a cooling jacket and a heat exchanger.

The rotor chamber is filled with the pumped liquid, which is circulated through the heat exchanger by an auxiliary impeller, the liquid also lubricates the bearings.
