SQ-DHF(T) pumps,booster pump system, are built on the basis of DHF pumps. The main difference between the DHF and the SQ-DHF(T) pump is the variable frequency drive.

Enhanced with the SQ-Drive, SQ-DHF(T) pump together with the appropriate sensor is turned into an intelligent, variable speed booster pump system.

The SQ-Drives adjust the motor speed which in turn provides constant pressure or differential pressure to the flow rate.
