For Flow Machines

Replaces FLOW oem # 020079-1 Made for Flow Hyperjet intensifier systems operating at 87,000 psi. This assembly helps drive the intensifier to maintain consistent movement, pressure, and performance. It is typically replaced during rebuilds or when wear affects pressure stability or operation.

Service tip: During installation, inspect adjoining seal surfaces, plungers, retaining hardware, and low-pressure seals for scoring, flattening, or uneven wear. Replacing worn mating components at the same time helps protect the new piston assembly and reduces the chance of pressure instability after startup.
