Function of the Pump Made Ready Assembly

The TS2021NP-VRT3-310EZ assembly helps:

• Deliver up to 5.6 GPM of water flow
• Produce operating pressures up to 3,500 PSI
• Regulate system pressure through the integrated VRT3-310EZ unloader valve
• Protect the pump during bypass operation with the thermal relief valve
• Reduce installation time with a factory-configured assembly
• Provide reliable, high-performance cleaning for demanding commercial and industrial applications

The low-speed 1,450 RPM design reduces wear and operating temperatures, helping maximize pump longevity and performance.

Common Signs Replacement Is Needed

Replace the pump assembly if you notice:

• Low operating pressure
• Reduced water flow
• Excessive pump noise
• External water or oil leaks
• Pump overheating
• Unloader valve malfunction
• Cracked or damaged pump housing
• Excessive internal wear
• Thermal relief valve malfunction

Replacing the complete pump assembly restores pressure washer performance while minimizing service time and equipment downtime.

Installation & Service Notes

• Shut down the pressure washer and relieve all system pressure.
• Verify compatibility with the drive system, shaft size, horsepower, and mounting configuration.
• Install the pump according to the manufacturer's specifications.
• Connect the water inlet, high-pressure outlet, and required plumbing.
• Verify the VRT3-310EZ unloader valve and thermal relief valve are properly installed.
• Prime the pump with water before startup.
• Inspect the system for leaks and verify proper operating pressure after installation.

Important: Never operate the pump without an adequate water supply. Running the pump dry or allowing prolonged bypass operation without a functioning thermal relief valve can significantly reduce pump service life.

Maintenance Recommendations

• Inspect the pump regularly for leaks and abnormal operating noise.
• Check pump oil level and service according to General Pump maintenance recommendations.
• Verify proper operation of the VRT3-310EZ unloader valve.
• Inspect the thermal relief valve periodically for proper function.
• Flush the system after use when pumping dirty or corrosive water.
• Use only genuine OEM General Pump replacement parts and accessories to maintain maximum performance, reliability, and long service life.
