Common Signs Replacement Is Needed

Replace the pump if you notice:

• Reduced operating pressure
• Decreased water flow
• Water or oil leaks
• Excessive operating noise
• Cracked or damaged pump housing
• Excessive internal wear
• Loss of cleaning performance
• Pump failure during operation

Replacing a worn pump restores cleaning performance while reducing equipment downtime.

Installation & Service Notes

• Disconnect electrical power before servicing.
• Relieve all system pressure.
• Verify compatibility with the motor shaft, flange mount, RPM, horsepower, and pressure requirements.
• Install the pump according to the manufacturer's specifications.
• Connect the water inlet and high-pressure discharge plumbing.
• Fill the crankcase with the recommended pump oil if required.
• Prime the pump with water before startup.
• Verify proper operation and inspect for leaks after installation.

Important: Never operate the pump without an adequate water supply. Running the pump dry can quickly damage internal plungers, seals, and valves, significantly reducing pump service life.

Maintenance Recommendations

• Check pump oil level and service according to AR maintenance intervals.
• Inspect seals, valves, and fittings regularly.
• Maintain clean, filtered inlet water to minimize internal wear.
• Flush the pump after use when pumping dirty or corrosive water.
• Use only genuine OEM AR replacement parts and approved lubricants to maintain optimum pump performance, reliability, and long service life.
