Pump installation height
Thread Content
The feed water pump is installed in an inverted configuration; the water temperature is 80 degrees. The model of the pump is ISR60-50-160, with a flow rate of 25 m3/h, a head of 32 m, and a net positive suction head of 2 m. The local loss at the pump inlet is 1.5 m. The installation height of the pump is H = 2 + 1.5 + 0.3 = 3.8 m. I would appreciate it if experts could advise me on whether this is appropriate
Since the inlet is installed by pouring, it is sufficient to ensure that the inlet tank is also at a height such that the pump inlet head loss plus the inlet pipe losses do not exceed 2 + 1.5 meters.
The water pump is installed too high, which is not appropriate; the tank can be placed higher
It’s the other way around – the tank is at least 3.8 meters higher than the water pump
The lowest liquid level in the tank should be XX meters higher than the pump. What about the pressure inside the tank?
What do you need to do? The conditions aren’t clear
Theoretical calculations are correct, but in practice abnormal operating conditions must also be taken into account; therefore, a margin needs to be reserved
