RKV4G30ADF24C2G 4.0 GPM 3000 PSI Triplex Pump | 3400 RPM

RKV4G30ADF24C2G | 4 GPM 3000 PSI Gas Engine Pump with Gymatic Unloader, 1 in. Hollow Shaft

The RKV4G30ADF24C2G is an Annovi Reverberi RK triplex plunger pump rated 4.0 GPM at 3,000 PSI at 3400 RPM, with a Gymatic 3/B unloader already installed. It slides onto a 1 in. engine shaft, bolts to the engine face, and is ready to plumb: no belts and no separate unloader to buy.

At 4 GPM and 3,000 PSI it is the standard rating for contractor and rental gas machines, and the Gymatic’s built-in bypass means no external bypass hose. The crankshaft-driven triplex runs ceramic plungers on aluminum connecting rods, and rebuilds with a kit when the seals finally wear.

What’s in the Box

• RKV4G30ADF24C2G pump with F24 engine flange

• Engine mounting bolts and lock washers

• 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 or larger (11 HP class and up).
• Detergent: this version has no chemical injector. For one built in, see the RKV4G30ADF24C2I.

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.
