   Hydrotest pump is a common procedure used to check fluid pressure vessel, such as, cylinders, boiler, tubes pipe, valves, castings, components etc. Hydrotest pump is also a common testing procedure to verify pressure vessels do not leak or have manufacturing flaws. Hydro testing pumps & equipments are important for pressure vessels in the interest of device safety, and durability under operating pressure.  The pressure vessel to be tested is located within a sealed vessel. The sealed vessel is filled with an incompressible fluid, typically water or oil. The pressure test vessel is then subjected to a known internal pressure for a known duration. The known internal pressure is normally a significant percent greater than the maximum operating pressure of the device (typically 150%). The applied pressure causes the test vessel to expand, instrumentation, which is already in place, are then read to determine the total and permanent expansion that the test chamber (external) undergoes. A physical and visual inspection then follows the hydro test to determine that the device being tested has not been damaged or permanently distorted due to the test pressure.  Pressure vessels may be re-verified by subjecting the vessel device to a proof-pressure test. The proof-pressure test is commonly referred to as a "modified hydrostatic test". The pressure vessel is subjected to a known pressure for a predetermined time. During and following the proof-pressure test, the pressure vessel is inspected for abnormal distortion or failure.  PressureJet offers wide range of hydro test pump ranging from 1 lpm to 773 lpm and pressure up to 2800 bar. Hydraulic test pump is either electric motor driven or engine driven. Pressure Jet also offers hydrostatic pressure testing pumps & equipments with pre-filling cum pre-pressurizing cum pressure building system. For large volume of hydro test combine hydrostatic pressure testing unit is most preferred solution. This hydrostatic pressure testing equipment is compact, efficient & cost effective, available in different combinations of pressure and flow. The unique automatic hydro test controller is a standard feature of this system. Otherwise also for large quantity, automatic hydrotest controller is very useful to improve productivity thru even a Kay man.  Though theoretically water is considered as non compressible fluid, it requires considerable amount of feeding to raise the pressure.
