Difference between self priming pump and mixed flow pump

Self-priming pump

 

Mixed flow pump with horizontal mixed flow pump, vertical long shaft mixed flow pump, submersible mixed flow pump, self suction pump, horizontal self suction pump, vertical self suction pump, strong self suction pump.

Horizontal mixed flow pump need to add at the end of valve, can be driven by a motor or a diesel, the long axis vertical mixed flow pump is the impeller immersed in water, can be driven by a motor or a diesel, diving mixed flow pump is the pump submerged in water, the motor drive.

Self priming pump, whether horizontal or vertical, is the whole pump and drive motor or diesel engine on the ground.

Both advantages and disadvantages: mixed flow pump efficiency, energy conservation, but the cost is high, if it is vertical long axis of the mixed flow pump, can be extended with the shaft, take to the ground more than 10 meters from the water. Self priming pump is simple, low efficiency, the initial investment is small, can only suck on the ground not more than 10 meters of water (generally not more than 6 meters).

If it is temporary water, it is recommended to use the self priming pump, if long-term water, it is recommended to use axial flow pump.
