A water pump is a mechanical device that transports or pressurizes liquids.can be improvedorThe discharge is achieved by the rotation of the impeller driven by the electric motor drive shaft.It will be driven by the original motivemechanical energyOr other external energy is transmitted to the liquid to increase the energy of the liquid. It is mainly used to transport liquid, including water, oil, acid-base liquid, emulsion, suspended lotion, liquid metal, etc. It can also transport liquid, gas mixture and liquid containing suspended solids.

Impellers can be classified according to their mechanical structure: forward bending, backward bending, and radial.

It can be divided into single suction and double suction according to the suction method. It can be divided into open, closed, and semi open (closed) forms.

According toTransported liquidsPH and oxidation degree, particle size, temperatureDifferent types of water pump impellers have different forms and materials.
The materials of water pump impellers mainly include five categories: cast iron impellers, aluminum alloy impellers, brass impellers, stainless steel impellers, plastic impellers, etc.

Neutral liquids generally require cast iron impellers, brass impellers should be used for oil, and sanitary food grade fluid materials should be selectedFood grade stainless steel impellerplastic material、Aluminum alloy impeller. Corrosive liquids are requiredSelect different corrosion-resistant impellers based on the usage environment, acidity and alkalinity, and degree of liquid oxidation.
