According to the pump selection principle and selection of basic conditions, the specific operations just as follows:
1.According to the arrangement, terrain conditions, water level conditions, operating conditions of the device, determine to select horizontal, vertical, or other type (pipeline, submersible type, non-clogging type, self-priming, gear, etc.) pump.
2.According to the nature of the liquid medium to determine the washing machine, hot water pump or pumps, chemical pumps or corrosion pump or trash pump, or the use of non-clogging pump. Pump installed in the blast area should be based on grade explosive areas, with the corresponding explosion-proof motor.
3.According to the size of the flow to determine the menu suction pump or double suction pump; according to head level, to choose menu-stage pump or a multi-stage pump, high speed pump or low speed pump (air conditioning pump). The efficiency multi-stage pump is lower than the single-stage pump. If menu-stage pump and multi-stage pumps both can be used at the same time, the first choice is single-stage pump.
4.Determine the specific type of pump: When determine the series of the pump, you can press the maximum flow rate,take 5% -10% margin to enlarge after lift the two main parameters of performance in the series or type spectrum characteristic curve to determine the specific type
