Function of the Pressure Washer Pump

The CKC26/24-GR pump helps:

• Deliver up to 7.0 GPM of water flow
• Generate operating pressures up to 3,500 PSI
• Provide powerful commercial and industrial cleaning performance
• Operate efficiently at low pump speeds
• Reduce vibration, heat buildup, and internal wear
• Maximize equipment uptime and pump service life

Its heavy-duty gear-drive triplex design provides exceptional durability and efficiency for demanding professional cleaning applications.

Common Signs Replacement Is Needed

Replace the pump if you notice:

• Reduced operating pressure
• Decreased water flow
• Water or oil leaks
• Excessive operating noise
• Damaged seals or valve assemblies
• Cracked or damaged pump housing
• Excessive internal wear
• Pump failure during operation

Replacing a worn pump restores system performance while minimizing costly equipment downtime.

Installation & Service Notes

• Shut down the pressure washer and disconnect the engine before servicing.
• Relieve all system pressure.
• Verify compatibility with the 1-1/8-inch shaft, gear-drive configuration, horsepower requirements, and system specifications.
• Install the pump according to Comet's installation guidelines.
• Align the gear-drive components correctly to prevent premature wear.
• Fill the crankcase with the recommended Comet pump oil before operation.
• 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 plungers, seals, valves, and other internal components, significantly reducing pump service life.

Maintenance Recommendations

• Check the pump oil level regularly and change the oil according to Comet maintenance intervals.
• Inspect the UD-10 seals and UD-31 valve assemblies during routine maintenance.
• Maintain clean, filtered inlet water to minimize internal wear.
• Inspect gear-drive components for proper alignment and lubrication.
• 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.
