According to the pump selection principle and the selection of basic conditions, the specific operation is as follows: 1, according to the layout of the device, topography, water conditions, operating conditions, to determine the choice of horizontal, vertical and other types (pipeline, submersible, Type, non-clogging, self-priming, gear-type, etc.) pump. 2, according to the nature of the liquid medium to determine the water pump, hot water pump or pump, chemical pump or corrosion-resistant pump or impurity pump, or non-clogging pump. Pumps installed in the explosive area should be based on the explosion area level, using the appropriate explosion-proof motor. 3, according to the size of the flow, to determine the menu suction pump or double suction pump; according to the level of the head, single-stage pump or multi-stage pump, high speed pump or low speed pump (air conditioning pump) Single-stage pump and multi-stage pump can also be used when the first choice of single-stage pump.
