AR ANNOVI REVERBERI Upgrade Pump Head Kit for Pressure Washers RMW2.2G24 — 2400 PSI 2.2 GPM with Unloader & Thermal Relief

The AR ANNOVI REVERBERI RMW2.2G24 Upgrade Pump Head Kit is a direct-replacement pump head assembly for compatible RMW2G and RMW2.2G pressure washer pumps, pre-assembled with an unloader and thermal relief valve for 2400 PSI at 2.2 GPM performance.

If you need a reliable pump head replacement that matches the stroke and fittings of specific Annovi Reverberi RMW2 series units, this kit provides a factory-style assembly ready to install. It is built to the original specifications for RMW2G and RMW2.2G pumps only; using it on incompatible models (for example RMW2.5G) risks damage because of differing stroke lengths. Read compatibility details carefully and gather your unit’s model and serial information before ordering to avoid returns.

Will this pump head fit my pressure washer model?

Compatibility is specific: the RMW2.2G24 kit is designed for Annovi Reverberi RMW2G and RMW2.2G pumps only. It does not fit RMW2.5G models, and installing it on other stroke-length variants can cause pump failure.

• Check your pump model stamped on the housing (RMW2G or RMW2.2G).
• Confirm OEM part numbers and serial/type codes where available.
• Contact the seller with model, serial, and engine HP if unsure.

What performance and safety components are included?

The kit arrives as a complete pump head assembly with an installed unloader valve and thermal relief valve so you get both pressure regulation and overheat protection out of the box. Maximum rated output is 2400 PSI at 2.2 GPM under correct application.

• Pre-assembled unloader valve for pressure bypass and control.
• Installed thermal relief to protect seals from overheating.
• All mating surfaces and ports finished for direct attachment to compatible pumps.

How do I prepare before installation to avoid returns?

Because fitment depends on pump stroke and specific model codes, gather as much identification information as possible before purchase. If the listed specs and pictures don’t clearly match your unit, ask for verification — supplying model, spec/type number, serial number, and engine horsepower speeds accurate cross-referencing.

• Photograph the pump label and serial plate to share with support.
• Compare mounting bolt pattern and port locations with the images provided.
• Do not swap this head onto RMW2.5G or other incompatible variants.

What should I expect during installation and first use?

Installation requires standard mechanical skills and basic tools; ensure seals are inspected and proper torque is applied to avoid leaks. After installation, prime and run the pump briefly while checking for correct pressure and leaks, following your machine’s break-in and safety procedures.

• Replace gaskets or O-rings if they show wear before assembly.
• Use correct torque values on head bolts to prevent distortion.
• Prime the pump and verify unloader operation at idle and full-throttle.

This pump head kit is tailored for technicians, service shops, and owners of Annovi Reverberi RMW2G or RMW2.2G pressure washers who need a direct, OEM-compatible replacement. It’s not for owners of RMW2.5G or other non-compatible variants; those customers should seek the correct part number to match stroke length. If you want help confirming fitment, gather your unit’s model, spec/type, serial number, and engine horsepower and contact the seller for assistance prior to purchase.
