However, the height can be moved but the pump will remain the same. For example we have this pump which can provide 125 feet of head. If we use it to pump water, the pressure will be around 54.25 PSI but if we were use it to pump milk then the pressure will be around 56.15 PS and that's because of the properties of the two fluids.
Convert pump pressure and pump head (static and stagnation pressure / head). Pump head can be calculated from pump pressure by `H = (P) / (ρ g) ` where : H = head P = pressure ρ = fluid density g = gravity constant . The stagnation pressure is calculated by `Pg = Ps + Pd ` `Pd = 1/2 ρ V^2 ` `V = (4 Q) / (pi D^2) ` where : Ps = static pressure
A gear pump is a type of positive displacement pump that uses interlocking gears to transfer fluids through a cyclical pumping action. These pumps are the heartbeat of many industrial applications, pumping life into systems through their relentless rhythm. Gear pumps can be categorized into two types: external and internal.

A gear pump uses a series of rotating gears to transfer fluid from one place to another. The rotating gears create a fluid seal between the housing of the pump and generate suction at the inlet side. As the pressure on the inlet side becomes lower than the surrounding pressure, the suction process of the fluid starts.
If the pressure is known, the equivalent head can be calculated by: Head, ft = Pressure, psi x 2.31 ft/psi . Example: The pressure gauge on the discharge line from the influent pump reads 75.3 psi. What is the equivalent head in feet? Head, ft = Pressure, psi x 2.31 ft/psi. Head, ft = 75.3 psi x 2.31 ft/psi. Head, ft = 173.9 ft . Head/Pressure
