Part No: V 04-3882-99
Pack of 1
V 04-3882-99: ASSY, PILOT SLEEVE, P400/P800 – A comprehensive replacement pilot sleeve and bore assembly designed to restore crisp, non-stalling cycle timing inside larger P400 and P800 series pump blocks.
V 04-3882-99: ASSY, PILOT SLEEVE, P400/P800 – A comprehensive replacement pilot sleeve and bore assembly designed to restore crisp, non-stalling cycle timing inside larger P400 and P800 series pump blocks.
Key Features
- High-capacity pilot sleeve assembly module scaled and engineered explicitly for P400 and P800 series pump blocks.
- Upgraded seal geometry cuts dynamic sliding drag to significantly improve low-pressure startup performance loops.
- Prevents high-pressure pilot signals from weeping or losing timing accuracy over long production schedules.
- Restores crisp alternating stroke timing profiles to maximize overall plant operating efficiency metrics on the floor.
- Extends the operational service lifecycle of non-wetted center blocks between planned maintenance warehouse cycles.
