Self Priming Dirty Water Pump

Working principle of self priming dirty water pump Ordinary centrifugal pump, if the suction liquid level is below the impeller, it is so inconvenient because it needs to fill water in advance when starting. In order to store water in the pump, a bottom valve is needed at the inlet of the suction pipe. When the pump is working, the bottom valve causes great hydraulic loss. The so-called self-priming pump is that water is not needed before startup (water is still needed for the first startup after installation). After a short time of operation, water can be sucked up by the function of the pump itself.

The self-priming height should refer to the vacuum degree that the self-priming dirty water pump can produce. That is to say, the height that the water source can rise under the action of atmospheric pressure. In practice, it generally refers to the vertical distance from the pump inlet flange to the water source level.

There are two ways to say the suction head, one is equal to the self-priming height, the other is the allowable installation height of the self priming dirty pump, that is, the vacuum degree of the pump, that is, the allowable installation height of the pump, unit meter.

Suction head = standard atmospheric pressure (10.33m) - NPSH - Safety (0.5m)

The suction head of self-priming pump is higher than that of general centrifugal pump.
