XMASS3G10N | 3 GPM 1000 PSI Pump 1750 RPM SS Head 24mm Shaft

XMASS3G10N

The Annovi Reverberi XMASS3G10N is a stainless-steel industrial
triplex plunger pump designed for demanding applications such as pressure
washing, reverse osmosis support, seal gland flushing, and wastewater odor
control. Part of AR’s XM-SS specialty stainless series, this model is rated up
to 3.0 GPM at 2,000 PSI and operates at a slow
1,750 RPM, combining strong cleaning performance with cool
running and long component life. With a 24 mm solid “N” shaft,
it is ready for direct-drive gas engine packages or belt/gearbox systems
where corrosion resistance and reliability are essential. :contentReference[oaicite:0]{index=0}

Performance and Pump Design

The XMASS3G10N is built on AR’s proven triplex plunger platform, using three
ceramic plungers phased 120° apart to deliver smooth, consistent pressure with
reduced pulsation. At 3 GPM and 2,000 PSI, it strikes a balanced duty point
for one-gun wash systems, RO support skids, and specialty industrial circuits
that need dependable pressure without excessive water use or spray mist. The
1,750 RPM speed further reduces heat and mechanical stress, supporting long
service intervals under frequent-duty operation. :contentReference[oaicite:6]{index=6}

• Max flow: up to 3.0 GPM (11.4 L/min).
• Max pressure: 2,000 PSI (140 bar) for robust impact on stubborn soils. :contentReference[oaicite:7]{index=7}
• Max speed: 1,750 RPM for cool operation and reduced wear. :contentReference[oaicite:8]{index=8}
• Max water temperature: 140°F (60°C) for cold and warm-water duty. :contentReference[oaicite:9]{index=9}

Triplex plunger advantages

Compared with axial or twin-piston pumps, the XMASS triplex layout offers
superior flow stability and a more linear pressure curve. That means better
operator control, more consistent cleaning, and less stress on downstream
components like hoses, guns, unloaders, and rotating nozzles. :contentReference[oaicite:10]{index=10}

• Smoother spray pattern with reduced hose “whip” and pulsation.
• Improved life for spray guns, lances, swivels, and turbo nozzles.
• More consistent pressure across varying hose lengths and nozzle sizes.

Stainless Wet-End Construction (XM-SS Series)

The XMASS3G10N belongs to AR’s stainless-steel XM-SS series, featuring a
SAE 316 stainless steel manifold that is fully
corrosion-resistant and purpose-built for aggressive or moisture-heavy
settings. This makes it ideal for specialty uses such as seawater handling,
RO support, chemical-assisted cleaning, and plant washdown where a brass head
could pit or discolor over time. :contentReference[oaicite:11]{index=11}

• 316 stainless steel manifold head for maximum corrosion resistance.
• Anticorrosion coated die-cast aluminum crankcase to further protect against harsh environments. :contentReference[oaicite:12]{index=12}
• Continuously lubricated Viton seals and triple-lip oil seals for extended life. :contentReference[oaicite:13]{index=13}
• Ultra-thick ceramic plungers designed to withstand variable temperature conditions. :contentReference[oaicite:14]{index=14}

Internal components and durability

Inside the stainless head, the XMASS3G10N uses precision ceramic plungers and
stainless steel valve assemblies to handle continuous pressure cycling and
frequent start–stop duty. High-pressure packings and low-pressure oil seals
are designed to keep water and oil separated while holding pressure at the
outlet. :contentReference[oaicite:15]{index=15}

• Plungers: 15 mm solid ceramic plungers for abrasion and thermal shock resistance. :contentReference[oaicite:16]{index=16}
• Valves: stainless steel valves and springs for consistent sealing at 2,000 PSI.
• Packings: high-pressure water seals and Viton low-pressure seals to protect the crankcase. :contentReference[oaicite:17]{index=17}
• Porting: dual 1/2″ F inlets and 3/8″ F discharge ports for robust plumbing. :contentReference[oaicite:18]{index=18}

Crankcase, Shaft, and Drive Options

On the drive end, the XMASS3G10N features a heavy-duty crankshaft supported
by high-quality bearings on both sides of the crankcase for precise alignment
and long life. The oil-bath crankcase uses approximately 14.5 oz
of pump oil, monitored via a sight glass for quick checks. The
24 mm solid “N” shaft accepts direct-drive couplings to gas
engines or pulleys for belt drive, giving builders flexibility in how they
hit the desired duty point. :contentReference[oaicite:19]{index=19}

• Crankcase: anticorrosion-coated die-cast aluminum with cooling fins.
• Bearings: premium, high-concentricity bearing positioning on both sides of the crankshaft. :contentReference[oaicite:20]{index=20}
• Oil capacity: approx. 14.5 oz for robust lubrication reserves. :contentReference[oaicite:21]{index=21}
• Shaft: 24 mm solid N-shaft ready for gas engine flange, belt drive, or gearbox input. :contentReference[oaicite:22]{index=22}

Serviceability

Like other XM-SS pumps, the XMASS3G10N is designed for straightforward
maintenance. Standardized repair kits bundle valves, water seals, and oil
seals, and the head and valve plugs are accessible with common shop tools,
helping minimize downtime in critical operations. :contentReference[oaicite:23]{index=23}

• Standard valve, water seal, and oil seal kits available from AR distributors.
• Accessible head bolts and valve plugs for quick inspection and rebuilds.
• Oil sight glass and drain plug simplify oil service intervals.
