Indicator Spring 1-11669 for Waterjet Pump Parts Supplier

The LP Poppet Spring 1-13907 is an essential component used in the low-pressure (LP) inlet valve system of Waterjet Intensifier pumps. Its main function is to provide consistent spring force for the LP poppet, ensuring accurate opening and closing during the water intake cycle.
This spring works together with the LP poppet, poppet basket, and valve seat to maintain stable inlet flow, prevent backflow, and support smooth pump cycling. It plays a key role in ensuring the intensifier chamber is properly filled with water before each high-pressure stroke.
A high-quality LP poppet spring is critical for maintaining inlet valve reliability, pressure stability, and overall pump efficiency.

Is LP Poppet Spring 1-13907 a Wear Part?

Yes — the LP Poppet Spring 1-13907 is a typical wear part.
Because it operates under repeated compression cycles, continuous valve movement, vibration, and hydraulic pressure changes, the spring gradually loses elasticity, weakens, deforms, or may eventually break.
If not replaced in time, it can cause poor inlet valve response, backflow, unstable water intake, and reduced pump performance.
Regular inspection and scheduled replacement are strongly recommended.
