RKV4G35D-F24C2I | 3.5 GPM 3000 PSI Triplex Pump Unloader Installed

RKV4G35D-F24C2I | 4 GPM 3500 PSI Gas Engine Pump with Unloader and Injector, 1 in. Hollow Shaft

The RKV4G35D-F24C2I is an Annovi Reverberi RK triplex plunger pump rated 4.0 GPM at 3,500 PSI at 3400 RPM, with a Gymatic 3/B unloader and chemical injector already installed. It slides onto a 1 in. engine shaft, bolts to the engine face, and is ready to plumb: no belts, no separate unloader to buy, no injector to add.

For a contractor rebuilding a 4 GPM gas machine, that is one part and one install. The crankshaft-driven triplex with ceramic plungers is built for daily work and rebuilds with a kit when the seals finally wear.

What’s in the Box

• RKV4G35D-F24C2I pump with F24 engine flange
• Gymatic 3/B unloader with chemical injector, installed
• Crankcase oil, pre-filled at the factory
• Vented dipstick. The pump ships with a shipping plug in the oil port. Swap in the dipstick before the first start.
• Engine mounting bolts and lock washers
• Operation manual and parts schematic
• 5-year Annovi Reverberi warranty

The shaft key is not included. It comes with your engine, and its size is set by the engine maker.

Will It Fit My Machine?

• Shaft: your engine has a 1 in. keyed horizontal shaft.
• Mount: the engine face matches the F24 flange bolt pattern.
• Engine size: 389cc to 420cc (13 HP class and up).
• Detergent: the injector draws chemical at low pressure. Use a low-pressure soap nozzle to pull detergent.

Not sure? Text a pump specialist at (505) 226-6061 with a photo of your engine tag and we’ll confirm the fit.

What Else You’ll Need

• Thermal relief valves and inlet filters: the thermal valve protects the pump during long bypass periods, and the filter keeps debris out of the valves.
