The Difference Between Cooling Water Pump And Chilled Water Pump

1. Different applications

Cooling water pumps are mainly used in chemical industry, food, brewing, pharmaceutical and so on.

Chilled water pump is a chilled water circulation system, which is generally used in large refrigeration equipment such as central air conditioners.

2, the temperature is different

Due to the special characteristics of the engine cooling water pump, such as high working water temperature (75-85 degree ), wide range of rotation speed (2000-5000r/min), and overall limitation of structure and size, compared with ordinary water pumps, the water inlet and outlet of the water pump have special characteristics. The complex design makes the flow direction and section shape of the inlet and outlet change sharply, which increases the hydraulic loss and reduces the efficiency.

The design temperature of the chilled water in the chilled water pump is 5 to 7 degree , but in fact, the temperature of the chilled water is only 2 to 4 degree in most of the year, that is, the pump is running at full power, which increases the energy loss of the pipeline and is wasted. The energy delivered by the pump operation.
