Can anyone help me?
I am testing a piston water pump. The input of the pump I connect to the water tank. The output of the pump I have fitted a water pressure gauge and a gate valve. If I shut the gate valve I have a reading showing on the pressure gauge (PSI/Bar). I want to know how I can work out the formula this pump can pump how many feet head of water without setting up a real test.

I still do not understand the formula,
Assume the gauge pressure reading is 50psi
Pa = atmospheric pressure apx. 14.7 psi
Pvp is the vapor pressure of the water at its temperature, which is about 0.5 psi for normal ambient temperatures
The density of water = 62.4 lbs/ft3
How can I apply this to the formula? If possible I need help for more explanation.

Why to shut the valve off? Do you intend to know the head in meters when the pressure is known in psi or do you want to know how much head the pump develops (without using the gauge)? For the first one, you already have the answer. For the second one, check the pipe system resistance.

The above posts are correct.
Exclusive of damage and overload, there is no maximum pressure (head) for a piston type pump.
If you increase the discharge pressure of this type pump, it will literally continue pumping until you have a mechanical failure, or your motor runs out of torque.

PSI = HP * 1538 / GPM

The out put (flow rate) of a piston pump actualy depends on the pump design. Piston travel, diameter, rpm, number of cylinders. At a given rpm, the flow is constant. The motor horse power should be sufficient to push the fluid to where it is directed.
