Pump lifting height
Thread Content
Is the pumping height of a pump determined by the outlet pressure or the head (without considering pipeline losses)? For example, if the inlet pressure of the pump is 0.3 MPa, the outlet pressure is 1.5 MPa, and the head is 70 meters, what is the theoretical pumping height of the pump in meters?

The outlet pressure is 1.3 MPA, so why is the head only 70? Have the pipeline losses and valve losses already been taken into account?
The inlet pressure is 30 meters of water column, and the head is 70 meters; that means 30 + 70 = 100 meters.
How did 190m come about? Please advise

Is the inlet pressure of the pump 0.3 MPa, the outlet pressure 1.5 MPa, and the head 70 meters? Will all these values be listed on the nameplate? ? ? It’s about 100 meters; the inlet pressure is 0.3 MPa. At a depth of 70 meters, it reaches 1.5 MPa, which represents an excessive load
With an outlet pressure of 1.5 MPa, the operation is stable; as long as the equipment is not damaged, this does not count as pipeline loss. The fluid can be pumped to a height of around 150 meters. Generally, the specifications provided by well-known brands are based on tests using water, and if the density of the fluid differs from that of water, there will be variations as well.
Theoretically, the higher the outlet pressure, the higher the water column that can be generated
It is determined by the head pressure; 10 meters of water column correspond to 1 atmosphere
