SXW Series

When only the highest pressures will do, the SXW Series is the powerhouse in AR North America’s industrial pump lineup. These models are engineered for continuous-duty work at extreme PSI levels, offering up to 5100 PSI while maintaining solid water flow for heavy cleaning and surface prep.

Built with a 24 mm solid shaft and operating at 1450 RPM, the SXW pumps combine a brass manifold, oversized ceramic plungers, and aluminum connecting rods for unmatched reliability in industrial environments.

If your applications demand intense pressure for cutting through grease, paint, or industrial buildup, the SXW series provides the muscle to get it done.

Key Highlights

• Flow & Pressure Options:
  • SXW15.35 → 3.96 GPM @ 5100 PSI
  • SXW21.350 → 5.55 GPM @ 5100 PSI
• Operating Speed: 1450 RPM
• Shaft: 24 mm solid shaft
• Oil Capacity: 32 oz
• Construction: Brass head, ceramic plungers, aluminum rods
• Weight: ~35 lbs — heavy-duty build for industrial applications

Why Choose the SXW Series?

Most commercial plunger pumps max out in the 3500–4000 PSI range. But for contractors, municipalities, and industrial facilities that require extra pressure for the toughest cleaning jobs, the SXW series stands out.

• 5100 PSI rating provides the cutting force needed for coatings removal, graffiti blasting, and deep surface prep.
• Still maintains flow options between 4–5.5 GPM, making it practical for a wide variety of applications.
• Engineered for long service intervals, with easily available AR rebuild kits.

The SXW is a true industrial-class pump, designed for operators who need consistent, reliable power under the harshest workloads.

Technical Specs

• SXW15.35 → 3.96 GPM, 5100 PSI, 15 HP input
• SXW21.350 → 5.55 GPM, 5100 PSI, 20 HP input

Shared specs:

• Bore: 35 mm
• Stroke: 15 mm / 21 mm depending on model
• RPM: 1450
• Oil Capacity: 32 oz

Typical Applications

The SXW series is purpose-built for jobs where standard contractor pumps aren’t enough. These are not light-duty washers — they are for serious cleaning, blasting, and industrial work.

Applications include:

• Graffiti and paint removal on concrete, brick, and metal
• Heavy equipment degreasing in mining, trucking, and rail
• Surface prep before coatings or sealants
• Industrial wash bays with extreme PSI needs
• Marine and shipyard cleaning for hulls and steelwork
• Oilfield and chemical plant washdown
• Municipal services requiring high-pressure sanitation

Service & Maintenance

As with all AR pumps, the SXW line is fully rebuildable. Contractors benefit from lower lifetime costs because they can service and maintain the pump rather than replace it.
