How much distance can a self priming sewage pump suction

The performance of a self-priming pump includes vertical self-priming height and horizontal self-priming distance. We generally refer to vertical height as suction head, but horizontal distance is also an important indicator of self-priming performance. The self priming pump room is generally built at a distance from the water source, and the exhaust performance of the self priming pump itself will directly affect the use of the pump.

Ordinary self-priming sewage pumps require a vertical suction head of no more than 5 meters and a horizontal self-priming distance of no more than 10 meters, such as ZW self-priming sewage pump, ZX self-priming pump, BZ direct connection self-priming pump, etc.

Open impeller self-priming pumps generally have a suction head of 6-7 meters and a horizontal distance of over 30 meters. The self suction distance will affect the flow rate of the self suction pump, and an excessively high suction head will result in extremely low flow rate.

Vacuum assisted self-priming sewage pump is a type of pump that combines self-priming pump and vacuum pump. It uses the suction performance of the vacuum pump to instantly extract the air in the pipeline. After adding water, the control cabinet receives a liquid level sensor signal, and the vacuum pump stops working. The vertical suction head of the vacuum assisted self suction pump can reach 9 meters, and the horizontal self suction distance can reach more than 200 meters.
