Double pump specifications, the use of self-regulating switch type double quantitative pump, further improve the energy-saving effect.

 

 

Use small capacity and large capacity dual ration pumps and switching valves to self-regulate confluence/separate switching through load pressure. When speed is needed, the large and small pumps combine to rotate at high speed and spit out large flow. When maintaining pressure, only small capacity pump running at low speed is selected to achieve substantial energy saving.
