- Designed to meet published performance ratings at 1750 RPM operation.
- Factory test report supports commissioning documentation and maintenance records.
- Warranty coverage supports contractor and industrial users running scheduled wash programs.
Operating Guidance
- Confirm motor compatibility with the NEMA 182–184 F17 1-1/8″ hollow shaft interface before installation.
- Use clean water supply and proper inlet filtration to protect valves, packings, and plungers.
- Verify supply flow is adequate for 4.0 GPM operation before extended runtime.
- Pair with an unloader/regulator sized to 4.0 GPM and set pressure at the nozzle under load.
- Use approved chemicals and flush with clean water after chemical exposure to support long-term corrosion protection.
Service & Maintenance
- Monitor oil level through the sight glass and service oil per manufacturer intervals.
- Inspect plumbing connections for leaks and air ingestion during routine inspections.
- Keep inlet strainers clean to prevent cavitation and pressure instability.
- Inspect packings and valves on a schedule matched to duty cycle and water quality.
- Use the parts schematic and test report to support rebuild planning and maintenance tracking.
Applications
- Commercial and industrial pressure washer systems and stationary wash bays.
- Fleet and vehicle-wash operations requiring consistent output and extended runtime.
- Agricultural and construction equipment cleaning and facility washdown.
- Municipal and contract cleaning facilities and sanitation programs.
- Harsh-environment wash applications where corrosion resistance is a priority.
