Alloy steel drilling pump valve spring with increased fatigue resistance for EMSCO, Gardner Denver and National, custom manufacturing

The spring is installed in the valve assembly of the hydraulic end of the mud pump and is constantly subjected to compression, recovery, and cyclic loads during operation. The product is made of alloy steel and is designed to reduce the risk of loss of elasticity, deformation, and fatigue failure during prolonged use. The spring is suitable for EMSCO F-500–F-1600, Gardner Denver PZ series, and National 7-P-50–12-P-160 pumps. It is possible to manufacture based on an old spring, drawing, equipment model, dimensions, and operating conditions. Custom manufacturing lead time is 1–2 weeks.
