XWM2128N-SX-CR 5.5 GPM 4060 PSI Pump | 1450 RPM with 1698 Kit

XWM2128N-SX-CR Industrial Triplex Plunger Pump

The AR North America XWM2128N-SX-CR is a corrosion-resistant industrial triplex plunger pump
built for service in marine, chemical, and industrial environments where uptime and material
integrity are non-negotiable. Delivering 5.5 GPM at 4,060 PSI at a controlled
1,450 RPM, it combines high working pressure with low-speed efficiency for
continuous-duty washdown, surface preparation, and process support systems.

• 5.5 GPM at 4,060 PSI for concentrated cleaning and process duty.
• Low-speed 1,450 RPM design to reduce heat, noise, and mechanical stress.
• Corrosion-resistant construction tailored for chemical and marine exposure.
• Based on the proven XWM2128N platform with enhanced performance via the 1698 kit.
• Left-hand shaft (SX) configuration for mirror-image and tight packaging layouts.

Corrosion-Resistant Construction for Harsh Environments

The XWM2128N-SX-CR is engineered specifically for environments where saltwater, industrial
detergents, and chemical vapors are part of everyday operation. A treated, corrosion-resistant
brass manifold helps prevent oxidation and scaling, while stainless steel valves maintain clean
seating surfaces over long duty cycles. Chemical-resistant Buna-N seals and ceramic plungers
preserve sealing integrity under fluctuating temperatures and pressures.

• Corrosion-resistant brass manifold to withstand marine and chemical atmospheres.
• Stainless steel valves for durable sealing and improved chemical compatibility.
• Chemical-resistant Buna-N seals for dependable leak protection.
• Ceramic plungers to resist abrasion, heat, and aggressive cleaning solutions.
• Material selection aimed at limiting premature wear in high-humidity, high-salinity zones.

Slow-Speed 1,450 RPM Powertrain

Operating at only 1,450 RPM, the XWM2128N-SX-CR runs cooler and smoother than high-speed
alternatives, which directly supports long service intervals and stable performance. The die-cast
aluminum crankcase features cooling fins to dissipate heat, and the oil bath lubrication system
provides continuous film protection to bearings, connecting rods, and the crankshaft.

• Low-speed operation reduces friction, noise, and vibration.
• Die-cast aluminum crankcase with cooling fins for thermal control.
• Oil bath lubrication for continuous protection of internal drive components.
• Oversized bearings to handle continuous-duty workloads and radial loads.
• Hardened crankshaft and connecting rods for extended mechanical life.

1698 Performance Optimization Kit

The integrated 1698 performance kit refines the hydraulic behavior of the XWM2128N-SX-CR by
optimizing inlet and discharge flow paths. This helps maintain stable pressure, reduce turbulence,
and limit pressure drop across the head, particularly in systems that see long runs, elevated duty
cycles, or frequent on/off cycling.

• Improved inlet and discharge routing for smoother hydraulic flow.
• Reduced turbulence to protect downstream valves, hoses, and accessories.
• More consistent pressure profile under varying load conditions.
• Enhanced energy efficiency at the pump head for demanding duty cycles.
• Better support for mission-critical systems requiring stable operating pressure.

Triplex Plunger Design & Hydraulic Performance

A triplex plunger configuration provides steady volumetric output with reduced pulsation,
protecting sensitive accessories and delivering predictable nozzle performance. Three ceramic
plungers cycle in sequence against stainless steel intake and discharge valves, resulting in a
smooth flow pattern that supports both single-gun cleaning and multi-outlet piping systems.

• Triplex design for low-pulsation, high-pressure water delivery.
• Precision ceramic plungers maintain consistent sealing surfaces over time.
• Stainless steel valve train for reliable opening and closing at rated pressure.
• Balanced hydraulic output for regulators, unloaders, and process controls.
• Suitable for high-duty washdown, degreasing, and industrial cleaning operations.

Maintenance, Monitoring & Service Access

The XWM2128N-SX-CR is designed so routine service can be completed quickly with standard tools.
Large valve caps provide direct access to valve assemblies, and a forward-facing oil sight glass
allows operators to confirm crankcase level and oil condition at a glance. A dedicated drain plug
supports clean, efficient oil changes, helping keep maintenance intervals consistent and downtime
controlled.

• Front-mounted oil sight glass for quick visual inspection.
• Vented fill/dipstick for proper crankcase ventilation and easy oil service.
• Large valve caps for straightforward access to valve kits.
• Convenient drain plug for controlled oil changes.
• Service-friendly layout to support in-house maintenance teams.

Integration, Mounting & SX Left-Hand Orientation

The SX designation identifies the XWM2128N-SX-CR as a left-hand shaft configuration, providing
flexibility when packaging multiple pumps, aligning with existing drive layouts, or designing
mirror-image systems. The compact footprint and standard mounting pattern make it suitable for
skids, bulkhead mounts, and enclosed pump rooms where space and alignment are critical.

• Left-hand shaft orientation (SX) for mirror-image and multi-pump layouts.
• Compact footprint for tight machinery spaces and enclosed cabinets.
• Standardized mounting pattern compatible with industrial baseplates and skids.
• Integrates with electric motors or engines via belt-drive or flexible coupling.
• Quiet, low-speed operation that helps reduce system noise and vibration levels.

Typical Marine & Industrial Applications

With its corrosion-resistant construction and high-pressure output, the XWM2128N-SX-CR is suited
for marine, process, and plant environments where equipment is frequently exposed to saltwater,
chemicals, or heavy contaminants. Its steady flow and low pulsation protect downstream equipment,
making it a solid choice for both cleaning and process-related duties.

• Marine vessel washdown, deck cleaning, and offshore maintenance.
• Chemical plant sanitation and equipment wash stations.
• Industrial degreasing and surface preparation operations.
• Wastewater treatment plant cleaning and process support.
• Food processing and packaging areas where corrosion resistance is required.
• Harsh-environment wash bays in coastal or high-humidity locations.
