SXWA4G50N | Triplex Pump, 4 GPM 5100 PSI, 1750 RPM, Dipstick & Oil

SXWA4G50N | 4 GPM 5000 PSI Triplex Pump, 1750 RPM, 24 mm Solid Shaft

The SXWA4G50N is an Annovi Reverberi triplex plunger pump rated 4.0 GPM at 5,000 PSI at 1750 RPM. It is built for jobs where pressure matters more than volume: stripping, prep work, baked-on grease and heavy equipment that a 3,000 to 4,000 PSI pump cannot cut through.

The heavy SXW frame carries 5,000 PSI at a relaxed 1750 RPM, so the plungers, seals and bearings run cool on long shifts. At that speed it couples straight to a standard 4-pole electric motor with no belts, or runs on a belt drive from a gas engine.

What’s in the Box

• SXWA4G50N pump with 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?

• Electric motor: 15 HP at 1750 RPM, direct coupled.
• Gas engine: V-twin, 570cc or larger (20 HP class) with a belt drive. Size the pulleys so the pump turns no faster than 1750 RPM.
• Plumbing: every hose, fitting, lance and nozzle must be rated for 5,000 PSI.
• Water: up to 140°F.

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 5,000 PSI and 4 GPM.
• Thermal relief valves, inlet filters and rail kits: the TPP140 thermal relief valve is a matched fit, and rails mount the pump to a base for belt drive.
