Hydrostatic Pressure Testing Pump

Hydrostatic testing (also referred to as hydro testing) is a type of test that fills a pressure vessel or pipe system with fluid to a specified PSI to ensure it can safely hold the amount of pressure it is rated for and maintain structural integrity.Hydrostatic testing is done by filling containers with water at high pressure until they reach their designated capacity; this allows engineers to see where leaks appear (signifying small holes) as well as find out how strong each welded seam really is.The pump casing cooling water passages, (if any) bearing jackets and seal chamber, etc. shall be tested at minimum 150 PSI. The steam, lubricating oil and cooling water piping system shall be tested at the 1.5 times of the Maximum Operating Pressure or 150 PSI whichever is greater.There are three common hydrostatic testing techniques that are used to test small pressure vessels and cylinders: the water jacket method, the direct expansion method, and the proof pressure testing method.
