The main factors affecting the head of sewage pump

As the name suggests, sewage pumps are mainly used to discharge sewage. The first thing to consider is whether 

the flow can be achieved and whether the head is sufficient. The most common problem is that the head is insufficient. 

Generally, a small flow may not have a big impact, but if the head is not enough, it will be done.

This is the case for customers we often encounter. Some users have measured that although the vertical distance between

 the reservoir or water tower and the water surface of the water source is slightly smaller than the pump head, the water lift 

amount is still small or the water cannot be lifted. What exactly is the reason for this? Is it the pump stealing the head? Is 

there any problem with the manufacturer's pump?

In fact, this is not the case. The main reason we analyze is: the pipeline is too long, the water pipe bends are many, and the 

water flow has too much resistance loss in the pipeline. Generally speaking, the resistance of 90-degree bends is greater than 

that of 120-degree bends. The head loss for each 90-degree bend is about 0.5-1 meter, and the resistance of every 10-meter 

pipe can cause the head loss for about 1 meter. In addition, some users also have arbitrarily pipe diameters of water pumps in 

and out of pipes, which also have a certain impact on the head.

Therefore, when customers choose sewage pumps, it is best to explain the specific usage situation, including the use cutoff, the 

pipeline used, etc., because these factors will affect the sewage pump head, so that Dingfei pump industry technicians can provide 

you with the most suitable pump and maximize efficiency.
