RSV3G34D-F40EZ 3.0 GPM 3400 PSI | 3400 RPM F40EZ-mount pump

RSV3G34D-F40EZ by Annovi Reverberi — RSV Series Triplex Plunger Pump with Integrated Unloader | 3.0 GPM | 3,400 PSI | Forged Brass Manifold | Bronze Connecting Rods | Easy Start | Fixed 12% Injector | 10,200 Cleaning Units

The RSV3G34D-F40EZ by Annovi Reverberi is an RSV Series triplex plunger pump with integrated unloader delivering 3.0 GPM at 3,400 PSI — engineered for direct gas engine coupling via the F40 1″ Shaft interface. Rated at 3.0 GPM and 3,400 PSI, the RSV3G34D-F40EZ delivers 10,200 cleaning units — through a forged brass manifold, solid ceramic plungers, bronze connecting rods, stainless steel valves, an integrated adjustable unloader, and a fixed 12% chemical injector in one factory-assembled pump body. Protected by a 5-year US limited warranty and built to be fully rebuilt rather than replaced. As part of Annovi Reverberi’s pump and unloader assemblies stocked and supported by WSHPWR, the RSV3G34D-F40EZ is the complete integrated triplex pump solution for gas engine-powered pressure washing at 3,400 PSI.

Easy Start — Zero Back Pressure at Every Startup

Bypass Opens at Engine Start. Engine Engages Freely. System Builds to Rated Pressure at Operating Speed.

The Easy Start feature on the RSV3G34D-F40EZ opens the bypass circuit at engine startup. The engine starts against zero hydraulic back pressure — no resistance from a pressurized pump on every pull. Once the engine reaches operating speed the bypass closes and the system builds to rated pressure. On machines that start dozens of times per shift, especially in cold weather, Easy Start removes hydraulic resistance from every single startup — reducing recoil starter wear and pull-cord effort every time.

Fixed 12% Chemical Injector — Integrated. Detergent Hose and Filter Sold Separately.

Injector Ready. Complete the System with the DETHOSE-FIL6X.

The RSV3G34D-F40EZ ships with a fixed 12% chemical injector integrated directly into the pump body. The injector automatically draws detergent when the downstream nozzle creates the correct pressure differential — no separate injector tee, no compatibility guesswork. What is not included: the detergent hose and filter. To complete the chemical delivery system, the DETHOSE-FIL6X 6ft Detergent Hose with Red Filter is the correct accessory — a 6-foot red chemical suction hose with inline filter sized for the RSV3G34D-F40EZ injector port. Keeps particulate out of the injector, extends injector service life, and gives the operator reach from a stationary detergent container on contractor rigs and wash stations.

Engine Compatibility — What Drives the RSV3G34D-F40EZ

F40 SAE J609a. 1″ Hollow Keyway Shaft. 7.0 EBHP Minimum. Predator and Honda Compatible.

Easy Start opens the bypass circuit at startup — the engine engages freely and builds to pressure at operating speed.
