As we all know, the role of the pump, is not limited to one industry.

See from the performance range of the pump, a giant pump the flow per hour up to hundreds of thousands of cubic meters the micropump flow per hour in dozens ml; pump pressure from atmospheric pressure to in up to 19.61Mpa (200kgf / cm2); transmission fluid temperature as low as -200 ℃ up to 800 ℃. Pumping a wide variety of liquids, such as the movement of water (water, sewage, etc.), oil, acid and alkali solution, suspension, and liquid metal.

Select pumps skills:
1. According to the layout of the device, terrain conditions, the water level conditions, operating conditions, to determine the pump (pipe, submersible, submerged, non-clogging, self-priming, gear, etc.), select the horizontal, vertical, and other types.

2. According to the nature of the liquid medium to determine the water pump, hot water pump or oil pump, chemical pump or Naifushibeng or impurities pump, or non-clog pump.

Pump installed in the explosion area, according to the explosion area level, corresponding explosion-proof motor.

3. According to the flow size to determine Menu suction pump or double suction pump; lift the level of the menu-level pump multistage pump, high speed pump or low speed pump (air conditioning pump), a multi-stage pump efficiency is lower than the single-stage pump, such as a menu-level At first, the single-stage pump can use the same pump and multi-stage pump.

In addition, spare pump rate can not be ignored: the normal operation of the pump, generally use only a single, two small pumps quite a large pump with parallel work, (referring to the head, the same flow rate), large pumps more efficient than small pump , it is rather to optional a large pump instead of two small pumps, but when any of the following situations, consider the co-operation of two pumps in parallel: a lot of traffic, a pump reach this traffic from the energy point of speaking.
