Miniature self-priming pump works: circular motion of the motor, the pump through the mechanical mechanism to reciprocate the diaphragm inside to compress, stretch the pump cavity (fixed volume) of the air, the role of the one-way valve in the drainage The formation of positive pressure at the mouth (the actual output pressure with the pump drain by the booster and the characteristics of the pump); in the suction port to form a vacuum, resulting in pressure difference with the outside world pressure. Under the effect of pressure difference, the water is pressed into the water inlet and discharged from the water outlet. Under the action of kinetic energy transferred by the motor, the water continuously inhales and discharges to form a relatively stable flow rate. More Search Keywords: water pump
The working principle of the centrifugal compressor is to work on the gas through the impeller, in the flow channel of the impeller and the diffuser, using the centrifugal pressure boosting effect and the deceleration and pressure expansion effect, the mechanical energy is converted into the pressure energy of the gas.

It is precisely because of this, mini pump BSP27250S, can guarantee self-priming height can be up to 5 meters, that is, the negative pressure of the suction port can be -50Kpa; outlet close to the case of blocking, the maximum output pressure to 2.7 kg; Unobstructed (what pipe, valve, nozzle are not connected), the maximum flow rate of 25 liters / minute.
