XWM2128N-CR | 5.5 GPM 4060 PSI Pump 1450 RPM Gear Box Drive

AR North America XWM2128N-CR

Corrosion-Resistant Industrial Pump

The AR North America XWM2128N-CR is a corrosion-resistant industrial plunger pump
designed for continuous-duty systems where reliability, chemical exposure, and
operating cost all matter. Delivering 5.5 GPM at 4060 PSI while
running at a controlled 1,450 RPM, it offers a balanced duty point
for high-pressure washdown, process cleaning, and mobile or stationary equipment
that must operate day after day with minimal disruption.

• High-pressure plunger pump for commercial and industrial cleaning systems.
• 5.5 GPM at 4060 PSI for strong impact and efficient coverage.
• Low-speed 1,450 RPM operation to reduce heat, noise, and wear.
• 24mm solid keyed shaft for belt-drive or direct-drive configurations.
• Built for continuous-duty applications in chemically aggressive environments.

Performance & Duty Point

The XWM2128N-CR is sized for systems that need strong cleaning pressure with a
manageable flow rate, allowing designers to build compact, efficient packages
without oversizing motors or engines. At 5.5 GPM, the pump supports single-gun
high-impact cleaning, multi-gun setups with appropriate valving, or long hose
runs where pressure stability is critical. The 4060 PSI rating provides enough
power to remove hardened deposits, concrete splatter, and industrial residues in
demanding service.

• Flow Rate: 5.5 GPM for controlled, high-impact cleaning.
• Pressure Rating: 4060 PSI for industrial-grade washdown.
• Speed: 1,450 RPM to control temperature and extend service life.
• Low-RPM operation supports continuous-duty cycles with reduced mechanical stress.
• Well suited for fixed wash stations, mobile rigs, and integrated OEM equipment.

Corrosion-Resistant Construction XWM2128N-CR

The “CR” designation identifies this model as a corrosion-resistant variant, using
materials selected for environments where chemicals, detergents, or saltwater
exposure are part of daily operation. A corrosion-resistant brass head provides
structural strength while limiting degradation, and stainless steel valves maintain
clean seating surfaces over long service intervals. Combined with ceramic plungers,
the pump is built to handle harsh washdown conditions when paired with compatible
detergents and correct water treatment.

• Corrosion-resistant brass manifold engineered for chemical and saltwater exposure.
• Stainless steel valves to maintain sealing performance under aggressive conditions.
• Ceramic plungers for abrasion resistance and thermal stability.
• Continuous-duty bearings sized for extended running hours.
• Materials selected for long-term reliability in industrial wash environments.

Wet-End Materials & Compatibility

The wet end of the XWM2128N-CR is designed for predictable performance where process
water, detergents, and environmental factors would quickly shorten the life of
lighter-duty pumps. While chemical compatibility still needs to be verified for
each installation, the use of corrosion-resistant brass and stainless steel creates
a robust base for washdown systems, coastal installations, and recycling facilities.

• Resists pitting and surface degradation when exposed to treated washdown solutions.
• Supports use in chemical washdown and sanitation systems when chemicals are compatible.
• Suitable for fresh water and properly conditioned process water circuits.
• Helps reduce premature head and valve replacement in high-moisture environments.

Triplex Plunger Design & Internal Drive

Internally, the XWM2128N-CR uses a triplex plunger configuration to deliver smooth,
low-pulsation flow. Three ceramic plungers operate in sequence, driven by a hardened
crankshaft supported by oversized bearings. The oil-bath crankcase provides constant
lubrication to the drive components, helping to control friction and heat over long
run times. This combination of slow-speed operation and robust mechanical design
supports predictable service life in continuous-duty systems.

• Triplex plunger design for smooth hydraulic output and reduced pulsation.
• Ceramic plungers provide a hard, wear-resistant surface for the seal interface.
• Hardened crankshaft designed for high-torque, low-speed operation.
• Oversized bearings to maintain alignment and reduce fatigue under continuous load.
• Oil-bath crankcase with integrated sight glass and vented dipstick.

System Integration & Mounting

With its 24mm solid keyed shaft, the XWM2128N-CR integrates readily
into belt-drive or flexible coupling systems driven by electric motors or engines.
The footprint and mounting pattern are suited for skid frames, mobile platforms,
and fixed pumps rooms, making it a practical choice for OEMs and system builders.
Whether used as a stand-alone pump or as part of a multi-pump bank, it offers a
repeatable layout that simplifies engineering and service.

• 24mm keyed shaft supports belt-drive and direct-coupled configurations.
• Standard mounting pattern compatible with industrial baseplates and skid systems.
• Appropriate for wall-mounted cabinets, mobile trailers, and plant pump rooms.
• Compatible with common unloaders, regulators, and safety relief assemblies.
• Suitable for use in single-pump or multi-pump manifolds as capacity requirements grow.

Maintenance, Serviceability & Monitoring

Routine maintenance on the XWM2128N-CR is straightforward. The integrated oil sight
glass allows fast checks of oil level and condition, and the vented dipstick provides
both fill access and proper crankcase ventilation. Valve and seal service can be
carried out with standard tools, making it practical for in-house technicians to keep
the pump in service without extended downtime. Each unit ships with break-in oil and
factory test documentation to support installation and commissioning.

• Pre-filled break-in oil to simplify first startup and run-in procedures.
• Oil sight glass for quick confirmation of crankcase level and oil appearance.
• Vented dipstick for easy oil service and pressure control inside the crankcase.
• Serviceable valves and seals designed for efficient replacement in the field.
• Factory-tested performance documentation included for reference and troubleshooting.

Typical Applications

The XWM2128N-CR is targeted at systems where corrosion resistance and dependable
pressure output are mandatory. Its flow and pressure rating make it suitable for a
broad range of industrial, municipal, and contractor applications that operate in
demanding conditions.

• Chemical washdown and sanitation systems in industrial plants.
• Environmental and municipal service fleets and equipment wash bays.
• Mobile pressure washing trailers serving commercial and industrial accounts.
• Construction and concrete cleanup on job sites and central wash racks.
• Recycling and waste-handling facility cleaning systems.
• Agricultural and livestock sanitation, barns, and equipment washdown.
