The NOV JWS-340 Special (P-5 Valve) is a reciprocating triplex well service pump rated to a maximum working pressure of 10000 PSI at 450 SPM, with factory liner sizes from 2.75 in to 4.5 in. It is engineered for intermittent high-pressure operation, where extreme pressure cycles in short bursts place heavy fatigue demands on pressure-bearing components such as the fluid end and crankshaft; its design focus is structural integrity under high cyclic stress. The power end uses an integrated high-strength forged steel frame rather than a welded steel or cast iron structure, giving superior rigidity. This configuration carries the P-5 valve system in the fluid end. We supply fluid-end replacement parts for this model to customers in Canada, the United States and international oil & gas markets.
