RSV35G40D-F40 Pressure Washer Pump | 3.5 GPM 4000 PSI

RSV35G40D-F40 by Annovi Reverberi — RSV Series Triplex Plunger Pump with Integrated Unloader | 3.5 GPM | 4,000 PSI | Forged Brass Manifold | Bronze Connecting Rods | Fixed 12% Injector | 14,000 Cleaning Units

The RSV35G40D-F40 by Annovi Reverberi is an RSV Series triplex plunger pump with integrated unloader delivering 3.5 GPM at 4,000 PSI — engineered for direct gas engine coupling via the F40 1″ Shaft interface. Rated at 3.5 GPM and 4,000 PSI, the RSV35G40D-F40 delivers 14,000 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 RSV35G40D-F40 is the complete integrated triplex pump solution for gas engine-powered pressure washing at 4,000 PSI.

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

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

The RSV35G40D-F40 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 RSV35G40D-F40 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.
