Function of the Electric Pressure Washer Pump

The FWS23530E pump helps:

• Deliver up to 3.6 GPM of water flow
• Generate operating pressures up to 3,000 PSI
• Provide reliable continuous-duty cleaning performance
• Operate efficiently at low pump speeds
• Reduce heat buildup and internal wear
• Extend equipment service life in demanding applications

Its heavy-duty triplex plunger design provides superior durability, smooth operation, and long-lasting reliability for professional electric pressure washer systems.

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 minimizing costly equipment downtime.

Installation & Service Notes

• Disconnect electrical power before servicing.
• Relieve all system pressure.
• Verify compatibility with the 1-1/8-inch flange shaft, motor horsepower, operating speed, and pressure requirements.
• Install the pump according to the manufacturer's specifications.
• Connect the 1/2" FPT inlet and 3/8" FPT outlet fittings.
• Fill the crankcase with the recommended pump oil before operation 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 the ceramic plungers, seals, and valves, significantly reducing pump service life.

Maintenance Recommendations

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