KMT PART NUMBER: 72101570

Discharge Seat | Sealing Head Outlet Seat | 90K | HJ-72101570

 

HJ WATERJET Part Number HJ-72101570 is a precision-engineered Discharge Seat (Outlet Seat) designed for KMT Streamline PRO II and PRO III 90,000 PSI (6,200 bar) waterjet intensifier pumps. This critical sealing head component provides a hardened sealing surface for the outlet check valve, ensuring efficient high-pressure water flow while minimizing leakage and maintaining consistent cutting performance. It is identified as the discharge/outlet seat in KMT sealing head assemblies and repair kits.

Manufactured to exact specifications, the HJ-72101570 discharge seat is engineered to withstand the extreme pressures generated during abrasive waterjet cutting. Regular replacement during sealing head maintenance helps restore pump efficiency, reduce downtime, and extend the service life of surrounding high-pressure components.

This HJ-72101570 Discharge Seat is commonly included in KMT outlet and inlet/outlet check valve repair kits, such as 72135447 and 72117819, together with the discharge poppet, poppet pin, compression spring, and other sealing head parts.
