XWAM7G40N | 7 GPM 4000 PSI Pump 1750 RPM 24mm Shaft Drive Duty

AR North America XWAM7G40N Triplex Plunger Pump

The AR North America XWAM7G40N is a heavy-duty triplex plunger pump designed for
industrial and commercial pressure washing systems that run long hours and require
consistent output. Delivering 7.0 GPM at 4,000 PSI at a controlled
1,750 RPM, this model combines high flow and high pressure to support
large cleaning zones, multi-gun manifolds, and demanding wash bay duty cycles.

Built around a 24mm solid keyed shaft, the XWAM7G40N integrates cleanly
with belt-drive or direct-drive power units, including gas, diesel, and electric
prime movers. Its ceramic plungers, stainless steel valves, and industrial-grade
seal package are engineered for continuous use in harsh environments where water
quality, chemicals, and heat can quickly expose weaker designs.

• Rated 7.0 GPM at 4,000 PSI for high-impact cleaning and high coverage rates.
• Operates at 1,750 RPM to reduce heat, vibration, and mechanical wear.
• 24mm solid keyed shaft for straightforward integration with industrial drives.
• Triplex ceramic plunger design for smooth, consistent hydraulic output.
• Built for continuous-duty operation in demanding industrial wash systems.

Key Specifications for System Designers

The XWAM7G40N is sized for systems where operators expect stable pressure and
predictable flow throughout the shift. Its specification set makes it suitable for
both new builds and retrofit upgrades where higher output is required without
oversizing the power unit.

• Flow Rate: 7.0 GPM (high-volume single-gun or multi-gun setups).
• Maximum Pressure: 4,000 PSI for aggressive cleaning and stripping.
• Speed: 1,750 RPM slow-speed operation for extended component life.
• Shaft: 24mm solid keyed shaft for belt or flexible coupling drive.
• Pump Type: Triplex plunger with three ceramic plungers in sequence.
• Valves: Stainless steel valves for reliable sealing and chemical resistance.
• Seals: Industrial-grade packings designed for continuous washdown duty.
• Crankcase: Oil-bath lubrication with sight glass and vented dipstick.
• Orientation: Compact, horizontal layout for skid frames and pump rooms.

Triplex Plunger Architecture & Internal Components

At the core of the XWAM7G40N is a triplex plunger assembly that converts rotational
energy into high-pressure hydraulic output with minimal pulsation. The forged brass
manifold handles pressure loads while maintaining dimensional stability, and the
ceramic plungers maintain a smooth sealing surface even after extended use with
hot water or detergents compatible with the pump’s materials.

• Forged brass manifold designed for long-term structural integrity.
• Solid ceramic plungers to resist scoring, abrasion, and thermal shock.
• Stainless steel inlet and discharge valves for consistent seating and long life.
• Hardened crankshaft and robust connecting rods for continuous-duty workloads.
• Precision-machined components to reduce vibration and mechanical stress.

How the XWAM7G40N Operates in the System

The XWAM7G40N is typically paired with an unloader or regulator, safety relief,
and proper inlet filtration. As the power unit brings the pump up to 1,750 RPM,
the plungers cycle in sequence, drawing water through the inlet circuit and
compressing it to operating pressure before discharge to the hose and gun circuit.
The slow-speed operation reduces temperature rise in the crankcase and minimizes
seal fatigue, which is critical in facilities running multiple shifts.

• Three-plunger sequencing delivers smooth flow with reduced pressure spikes.
• Consistent 7 GPM output supports long hose runs and distribution manifolds.
• Lower RPM reduces heat and extends lubricant and seal life.
• Compatible with industry-standard unloaders, regulators, and accessories.
• Designed to operate in continuous bypass when controlled by properly sized valves.

Benefits for Industrial and Commercial Users

In harsh washdown and heavy-cleaning environments, reliability and uptime matter
more than anything. The XWAM7G40N is built to maintain output and pressure even as
hours accumulate, supporting maintenance teams, contractors, and production staff
who rely on consistent water power to keep equipment and facilities in service.

• High impact cleaning performance for heavy soil, grease, and road film.
• Balanced design for stable operation on trailers, skids, and fixed frames.
• Durable materials to withstand detergents, humidity, and frequent cycling.
• Low-maintenance layout with easily serviced valves and seal kits.
• Supportable with standard service parts available through WSHPWR.com channels.

Typical Industrial & Commercial Applications

The XWAM7G40N is sized for applications where both flow and pressure are fully
utilized. It is well suited to high-production washing and surface preparation
tasks where operators need to move quickly across equipment, vehicles, or large
floor areas.

• Fleet and transportation wash bays for trucks, buses, and trailers.
• Municipal and public works yards handling refuse trucks and heavy equipment.
• Industrial wash racks for construction, rental, and mining equipment.
• Surface preparation for concrete pads, loading docks, and containment areas.
• Food and beverage facilities using high-pressure rinse where compatible chemicals are used.
• Contractor-grade mobile rigs serving commercial and industrial accounts.

Maintenance, Serviceability & Lifecycle Value

The XWAM7G40N is configured so that most routine service can be performed in-house
with standard tools. Daily checks focus on crankcase oil level, inlet filtration,
and quick inspection for leaks. Valve kits and seal kits are accessible without
dismantling the entire pump, helping reduce downtime and labor costs.

• Oil-bath crankcase with sight glass simplifies pre-shift inspection.
• Top-access valve caps for straightforward valve replacement.
• Serviceable seal packings to restore performance as hours accumulate.
• Stable mounting pattern for easy removal and reinstall during overhaul.
• Designed for long service intervals when operated within rated conditions.
