Gledewen Pressure Washer Pump Head AR43361 — Aluminum Replacement with Integrated Unloader & Thermal Relief Valve, Fits SRMW2.3/2.

The Gledewen AR43361 is a complete aluminum pump head assembly with an integrated unloader and pre-installed thermal relief valve designed as a direct replacement for Annovi Reverberi SRMW2.3G28 and SRMW2.4G28 pump heads.

This replacement pump head restores pressure-washer performance with an OEM-match design, corrosion-resistant aluminum construction, and factory-installed safety components for straightforward, reliable operation. It fits models listed under OEM numbers SRMW2.3GPM and SRMW2.4GPM and is intended for easy swap-in installation so equipment owners can minimize downtime and avoid complicated repairs.

How does this pump head restore my pressure washer’s performance?

Replacing a worn or damaged pump head with the AR43361 rebuilds the high-pressure section that generates your washer’s water flow and pressure. The one-piece design mirrors OEM dimensions so seals and ports align for predictable performance.

• Restores up to 2800 PSI and 2.4 GPM capability when matched with the correct pump unit.
• Includes an integrated unloader to protect the engine and control bypass flow.
• Thermal relief valve pre-installed to help prevent overheating during no-flow conditions.
• Aluminum construction improves corrosion resistance and reduces weight.

Is this part compatible with my Annovi Reverberi SRMW2.3G28 or SRMW2.4G28 model?

The Gledewen AR43361 is built to meet OEM specifications and is a direct replacement for part numbers SRMW2.3GPM and SRMW2.4GPM. Always compare the original part number, external dimensions, and port layout before purchasing to ensure a precise match.

• Designed to match OEM mounting points and seals for plug-and-play replacement.
• Check the original pump head’s part number (SRMW2.3G28 / SRMW2.4G28) against the AR43361 stamping or listing.
• Measure ports and bolt spacing if there is any doubt—minor measurement variances can occur.

What are the key durability and safety features included?

This assembly is manufactured and tested under quality controls to deliver stable operation across demanding cleaning tasks. Critical safety components are factory-installed so you don’t need to source separate unloaders or thermal relief valves.

• High-quality metal body with corrosion-resistant finish for longer life.
• Pre-installed thermal relief valve reduces overheating risk during prolonged no-flow periods.
• Unloader valve protects the drive system by diverting pressure when the trigger is released.
• Factory testing helps ensure leak-free seals and consistent pressure output.

How easy is installation and what should I check before fitting?

Installation is intended to be direct and straightforward: remove the old pump head and swap in the AR43361, reusing gaskets and fasteners where appropriate. Because dimensions are measured manually and displays can vary, always verify fit and part numbers ahead of swap.

• One-piece replacement simplifies alignment and reduces install time.
• Keep original seals or replace with new gaskets for best results.
• Confirm pump model and part numbers, then torque bolts to manufacturer specs.
• Perform a pressure and leak test after installation before full operation.

Who is this for: The Gledewen AR43361 suits technicians, rental fleet managers, and homeowners who own pressure washers with Annovi Reverberi SRMW2.3 or SRMW2.4 pump series and need a dependable, OEM-spec replacement pump head. It’s for buyers who want OEM-style compatibility, a pre-installed thermal relief valve and unloader for safety, and a durable aluminum assembly that restores up to 2800 PSI and 2.4 GPM cleaning capacity without extensive modification or custom fitting.
