What are the technical requirements for swimming pool circulation pumps?

 

 

The circulating water pump for swimming pools generally uses clear water centrifugal pumps, which can be divided into ordinary clear water centrifugal pumps and swimming pool special circulating pumps. The following is mainly based on the selection guide for swimming pool special circulation pumps.Material:Pumps used in swimming pools should be made of corrosion-resistant materials such as copper, stainless steel, and plastic to make impellers or pump casings.Skills requirement:1) The sum of the capabilities of the circulating water pump should be greater than or equal to the operating head required for filtration and backwashing of all systems.2) A cleanable hair filter must be provided before circulating the pump.3) Circulating pumps and motors should be easy to overhaul and maintain, and the design and construction of pumps and their components should be safe.4) The mechanical seal of the circulating water pump should be corrosion-proof and work well in the swimming pool operating environment.5) The size of the circulating water pump should be as compact as possible, and its electrical and mechanical structure is suitable for general swimming pool installation, load and environmental conditions.6) The pump motor can work at full load within the range of plus or minus 10% of the rated voltage.7) All pump motors should have thermal and current overload protection, set inside the motor or at the starting point of the line to provide locking rotation and running protection.8) Security protection level IP55.
