Product Description
The HJ WATERJET Hydraulic Auto Bleed Down Repair Kit, 60K (HJ-004694-1 or HJ-302008-1) is a precision-engineered maintenance repair kit designed to restore the automatic pressure relief (bleed down) function in waterjet intensifier pumps operating up to 60,000 PSI (4,100 bar).
The auto bleed down system is a critical safety and pressure management feature that automatically relieves trapped high-pressure water when the pump stops or cycles down. This prevents pressure from remaining locked inside the system, protecting both equipment and operators.
Over time, internal components within the bleed down assembly wear due to constant exposure to high-pressure cycling, contamination, and mechanical stress. The HJ-004694-1 or HJ-302008-1 Hydraulic Auto Bleed Down Repair Kit provides all necessary components to rebuild the system and restore proper pressure release function.
The HJ-004694-1 or HJ-302008-1 kit includes the following:
HJ-B-5701-2 Bleed Down Valve High Pressure Seal
HJ-B-5723-1 Bleed Down Valve Cone Seal
