Dooch Pump

The MQ-DRIVE is a Fully integrated multi-pump specific controller which includes 2 to 6 frequency inverters(one per pump) mounted in one compact unit. Since this product is applicable for any general inverter, it can be utilized without limitation of pump power.
For various pump such as booster, inline, fire, underwater pumps that are used in buildings in various types such as single stage volute, vertical multi-stage, centrifugal pump manufacturer pump, etc. One pump controller OPC-1000 and OPC-1001 are applicable for any general inverter, and this product enables the latest pump control function of pump inverter.

NSQ-XR(L) pumps are built on the basis of XR(L) pumps. It is supposed to be designated as standard product for individual inverter water pumps by the Chinese Architectural Society, and has been used in various sites such as Changsha Pepsi Cola Plant and major national facilities in China.
Even if one inverter or one pump is out of order, the other inverters can operate automatically. Enhanced with the NSQ-Drive, the XR(L) pump together with the appropriate sensor is turned into an intelligent, variable speed pumping system. Each frequency inverter mounted inside MQ-DRIVE can be a Master inverter” and it is possible to run all pumps in multi-controller mode and allows each pump of the system to become a lead pump.

For various pump such as booster, inline, fire, underwater pumps that are used in buildings in various types such as single stage volute, vertical multi-stage, centrifugal pump, etc. One pump controller OPC-1000 and OPC-1001 are applicable for any general inverter, and this product enables the latest pump control function of pump inverter.
The Dooch booster pump does not only features IP55 rated control panels, individual inverters as well as individual controllers, EMC filters and DC reactors, making it one of the world’s most reliable and precise control but also has cutting-edge competitiveness in terms of quality and price.

The MQ-DRIVE is a Fully integrated multi-pump specific controller which includes 2 to 6 frequency inverters(one per pump) mounted in one compact unit. Since this product is applicable for any general inverter, it can be utilized without limitation of pump power.
The pressure-resistant cylinder and flow passage components are fixed between the pump head and the pump casing by means of stay bolts. The NSQ-Drives are frequency converter integrated into the pump which adjusts the motor speed to provide constant pressure or differential pressure to the flow rate.
