• 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.
