Hydrostatic Test Pressure

Classification
Definition
Pressure to which the pump will be subjected to for a short duration to insure casting, seal, and gasket integrity.
Calculating: Hydrostatic test pressures can be to as much as 1.5 times MAWP, but may be limited by other factors such as the seal.
What is the hydrostatic test pressure?
Hydrostatic test pressure is the pressure to which the pump will be subjected to for a short duration to ensure casting, seal, and gasket integrity. This is achieved by sealing and pressurizing the pump when it is not in operation. Hydrostatic test pressures can be to as much as 1.5 times the maximum allowable working pressure, but may be limited by other factors such as the seal.
What is a hydrostatic pressure test used for?
A hydrostatic pressure test is used to check the integrity of a pump’s casting, seal, and gasket/s.
