87K Intensifier Low-pressure Cylinder

The 87K Intensifier Low-Pressure Cylinder is an OEM Flow replacement cylinder for PH2 HyperJet® intensifier assemblies operating in 87,000 psi applications. This cylinder supports the hydraulic side of the intensifier, housing the low-pressure piston and helping convert hydraulic force into the linear motion needed to drive the high-pressure plunger. It is a critical structural component during intensifier rebuilds, especially when cylinder bore wear, scoring, or dimensional damage can affect piston alignment and pressure stability.

• 87K Intensifier Piston Assembly (020079-1) — commonly serviced with low-pressure cylinder components during a full intensifier rebuild.
• 87K HyperJet® Intensifier Seal Carrier Cartridge (040015-1) — refreshes the high-pressure sealing package connected to the intensifier plunger side.
• Intensifier High-Pressure Plunger Assembly (010253-1) — works with the seal cartridge to restore sealing surface quality and pressure performance.
• 87K HyperJet® Intensifier Check Valve Assembly (020071-1) — helps maintain stable high-pressure water flow and prevent backflow during intensifier cycling.

Critical note: Inspect the mating piston, seals, end cap, and plunger components during replacement. Any scoring, uneven wear, or contamination inside the hydraulic or high-pressure sections can shorten the life of the new cylinder and reduce pump performance after startup.
