SQ-2DHM pumps,booster pump system, are built on the basis of DHM pumps. The main difference between the DHM and the SQ-2DHM pump is the variable frequency drive. Enhanced with the SQ-Drive, SQ-2DHM 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.
