Plunger Retainer, 60K | HJ-100011-1
The HJ-100011-1 Plunger Retainer is a replacement hydraulic component designed for 60K PSI H2O-Style waterjet intensifier systems. Also identified as Flow Waterjet 007029-1, this plunger retainer is used in the hydraulic section of compatible high-pressure waterjet pumps and intensifiers. This component is commonly described as a 60K Plunger Retainer, Plunger Retainer, or Plunger Retainer Biscuit. The part is associated with H2O Jet 60K hydraulic intensifier components and may be cross-referenced to Flow 007029-1 when servicing compatible equipment.
Frequently Asked Questions | HJ-100011-1
1. What is HJ Waterjet part number HJ-100011-1?
HJ-100011-1 is a direct replacement for H2O Jet 100011-1 Plunger Retainer used in compatible H2O Jet high-pressure waterjet intensifier systems. It is associated with 60K PSI (4,137 bar) applications.
2. What is the function of the HJ-100011-1 Plunger Retainer?
The plunger retainer helps secure and properly position the plunger assembly within the waterjet intensifier, supporting correct operation of the hydraulic and high-pressure components.
3. What is the Flow Waterjet equivalent of HJ-100011-1?
The commonly referenced Flow Waterjet cross-reference is 007029-1. Always verify compatibility with your specific pump configuration before installation.
4. What equipment uses HJ-100011-1?
It is used with compatible H2O Jet high-pressure waterjet intensifier/pump assemblies, particularly configurations operating at 60K PSI.
5. Is HJ-100011-1 the same as 100011-2?
No. The part numbers correspond to different configurations. HJ-100011-1 is associated with 60K PSI, while 100011-2 is associated with 40K PSI applications. Confirm the pump model and pressure configuration before ordering.
6. How do I know if HJ-100011-1 will fit my waterjet pump?
Check your pump/intensifier model, operating pressure, existing component part number, and manufacturer documentation. If your existing part is marked 100011-1 or the equipment documentation specifies it, that provides a strong identification match.
7. Can HJ-100011-1 be used on a 40K PSI system?
Do not assume interchangeability. Documentation distinguishes the 60K and 40K components, so the exact intensifier configuration should be verified before using the part.
8. What should I check before ordering HJ-100011-1?
Verify:
- H2O Jet part number: 100011-1
- Component: Plunger Retainer
- Pressure: 60K PSI
- Pump/intensifier model
- Existing part number
- Applicable Flow cross-reference, if relevant
- Dimensions/configuration against the equipment documentation
