The AQUALON HP Cylinder Liner .88 (Part 20497767) is a precision-manufactured high-pressure cylinder liner designed for use in 60 000 psi (≈4150 bar) waterjet pump systems featuring 0.88″ plungers. This liner fits inside the high-pressure cylinder of KMT-style pumps and serves as a durable wear surface that protects the cylinder bore from wear and scoring caused by repeated plunger movement.
It is a direct replacement for the discontinued KMT part numbers such as 10110419, 05132246, 05109624, 05121777, 05144712, 80080021, 20481574, 20418805 and matches those legacy specifications, ensuring compatibility with a wide range of KMT Streamline and similar intensifier pump models.
Because this liner acts as the primary contact surface between the plunger and the cylinder bore, it helps maintain reliable high-pressure sealing, reduces wear on more expensive components, and extends the service life of the pump assembly when replaced as part of scheduled maintenance.
