SQ2-Drive

SQ2-Drive is a single phrase variable frequency drive that manages pump performance to match awide range of system conditionsand requirements.Adjusting the pump speed is the most efficient means of controlling the pump flow and reducing theenergy consumption.
SQ2-Drive isamotor-independent structure,itcanbemounted directly on themotor or on the wall.

NSQP-2DHF(T) Series

NSQP-2DHF(T) series is built on the basis of DHF pumps.The main difference between the DHF and the NSQP-DHF(T) pump is the variable frequency drive.Enhanced with the NSQ-Drive, NSQP-2DHF(T) series with the appropriate sensor is turned into an intelligent, variable speed pumping system.The NSQ-Drives adjust the motor speed which in turn provides constant pressure or differential pressure to the flow rate. NSQP-2DHF(T) isalso equipped with the 7" touch screenmonitor that isembedded into the panelwhich features the lastest GUl.
