XMASS3G15E-F33 | 3 GPM 2000 PSI Pump 1750 RPM SS Head Duty

XMASS3G15E-F33

The Annovi Reverberi XMASS3G15E-F33 is a compact, stainless-steel
industrial triplex plunger pump engineered for professional cleaning systems,
OEM electric pressure washer packages, and fixed wash stations where uptime
and corrosion resistance are critical. Rated up to
3.0 GPM at 2,000 PSI and designed for
1,750 RPM operation, this “E” version pump features a
5/8″ hollow shaft with F33 electric motor flange for
direct mounting to 56C-style electric motors. With a stainless head, ceramic
plungers, and frictionless aluminum connecting rods, the XMASS3G15E-F33
delivers long service life in demanding, moisture-prone, or chemically
assisted cleaning environments.

• Stainless-steel head triplex plunger pump for corrosive or washdown environments.
• Delivers 3.0 GPM at up to 2,000 PSI for strong, efficient cleaning performance.
• 1,750 RPM operating speed for cooler running and extended seal, bearing, and rod life.
• E-version 5/8″ hollow shaft with F33 flange for direct-drive electric motor mounting.
• Lightweight, compact design – approximately 17 lb – ideal for cabinets, carts, and OEM skids.

Performance and Pump Design

The XMASS3G15E-F33 is built on AR’s proven three-piston (triplex) volumetric
design, which produces smooth, consistent high-pressure output with reduced
pulsation. At 3 GPM and up to 2,000 PSI, it hits a versatile
duty point for single-gun wash bays, wall-mount electric pressure washers, and
process-cleaning rigs that require reliable pressure without excessive water
consumption or overspray. The slow 1,750 RPM speed helps keep oil temperatures
controlled and reduces mechanical stress on internal components.

• Balanced duty point: 3 GPM @ up to 2,000 PSI for effective cleaning and rinsing.
• Triplex plunger layout: three plungers phased 120° apart to minimize pressure ripple.
• Electric-drive friendly: optimized for direct coupling to NEMA 56C-frame electric motors.
• Supports cold and warm water use with a typical maximum inlet temperature of 140°F (60°C).

Triplex plunger advantages

• Smoother spray for better operator control and more uniform cleaning results.
• Reduced stress on guns, lances, turbo nozzles, swivels, and rotating heads.
• More consistent performance across a range of nozzle sizes and hose lengths.

Stainless Head Construction – XMASS3G15E-F33

The XMASS series uses a stainless-steel manifold head instead
of traditional brass, making this pump a strong choice wherever detergents,
sanitizers, or harsh environments can shorten the life of standard heads. This
model is optimized for corrosion resistance while maintaining the same compact
crankcase footprint as brass-head XMA versions.

• Stainless-steel manifold head for superior corrosion resistance.
• Ideal for food, beverage, and packaging plants that require regular washdown.
• Well suited to coastal and marine facilities exposed to salt air and spray.
• Helps maintain sealing surfaces where brass might pit, discolor, or erode over time.

Internal materials and wet-end durability

• Plungers: 15 mm solid ceramic plungers resist scoring, abrasion, and thermal shock.
• Valves: stainless steel valves and springs for reliable sealing at up to 2,000 PSI.
• Sealing system: high-pressure packings and low-pressure oil seals to protect the crankcase.
• Porting: 1/2″ F inlet and 3/8″ F outlet for robust, industry-standard plumbing.

Crankcase, Shaft, and F33 Electric Flange

The drive end features a die-cast aluminum crankcase with cooling fins, an
oil-bath lubrication system, and a side sight glass for easy oil checks. The
5/8″ hollow electric shaft with F33 flange
is designed to bolt directly to 56C-style motors, eliminating the need for
separate base-plate alignment in many systems and keeping the overall package
compact and clean.

• Crankcase: die-cast aluminum with cooling fins for efficient heat dissipation.
• Connecting rods: frictionless aluminum alloy rods for smooth, efficient motion.
• Oil capacity: approximately 14.5 oz for robust lubrication reserves.
• Shaft/flange: 5/8″ hollow “E” shaft with F33 electric motor flange for direct drive.

Serviceability

• Standardized valve, water seal, and oil seal kits available from AR distributors.
• Oil sight glass and fill/dipstick for fast oil level checks and changes.
• Head bolts and valve plugs positioned for straightforward teardown and rebuilds.

Typical Applications

With its stainless head, compact direct-drive layout, and 3 GPM / 2,000 PSI
performance, the XMASS3G15E-F33 is a versatile choice for commercial and light
industrial users who need reliable cleaning in demanding environments.

• Food and beverage plants – washdown, conveyor cleaning, and floor rinse.
• Meat and poultry processing – sanitation and foam knockdown systems.
• Coastal and marine facilities – docks, boatyards, and salt-air exposed equipment.
• Manufacturing and recycling – equipment wash stations and bin cleaning.
• General maintenance wash bays – forklifts, carts, light trucks, and service vehicles.
• OEM electric skids and cabinets – wall-mount and enclosure-style pressure washer packages.
