RKSS11.11N | Stainless Triplex Pump, 3 GPM 3000 PSI, 24mm Shaft

RKSS11.11N | Stainless Triplex Pump, 3 GPM 3000 PSI, 1450 RPM, 24 mm Solid Shaft

The RKSS11.11N is an Annovi Reverberi triplex plunger pump with a stainless steel head, rated 2.9 GPM (11 L/min) at 3,000 PSI at 1450 RPM. Where a brass head pits and corrodes, stainless holds up: caustic cleaners, sanitizers, chlorides, salt air and the daily washdown cycles of food, chemical and marine plants.

It runs on a 24 mm keyed solid shaft for belt drive, and at 1450 RPM the seals and valves run cool for long service between rebuilds. At just under 3 GPM it is sized for single-operator washdown stations and compact carts where steady output and corrosion resistance matter more than volume.

What’s in the Box

• RKSS11.11N pump with stainless steel head and 24 mm keyed solid shaft
• 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.
• Operation manual and parts schematic
• 5-year Annovi Reverberi warranty

Will It Fit My Machine?

• Drive: belt drive. Size the pulleys so the pump turns no faster than 1450 RPM.
• Electric motor: 7.5 HP.
• Gas engine: 270cc or larger (9 HP class).
• Water: up to 140°F. Check chemical compatibility with your cleaning agents.

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

What Else You’ll Need

The pump is sold bare. The unloader, thermal relief valve, inlet filter and rail kit are sold separately:

• Unloader valves: choose one rated for at least 3,000 PSI and 3 GPM. A stainless unloader keeps the whole wet end corrosion resistant.
• Thermal relief valves, inlet filters and rail kits: rails mount the pump to a base for belt drive.
