How the SXW15.35HT Works

Triplex Plunger Output at Hot-Water Temperatures

• Three plungers pressurize water in sequence to deliver a steady, consistent high-pressure stream with reduced pulsation.
• Ceramic plungers reduce friction and help protect seals during hot-water operation and high-pressure duty cycles.
• Heat-rated seals and stainless valves are designed to maintain sealing performance during thermal cycling and chemical exposure.

Low-Speed Longevity

• Operating at 1,450 RPM helps reduce internal heat, friction, and vibration compared to high-RPM pump designs.
• Forged brass manifold construction supports long service life under repeated hot-water pressure cycles.
• Oil-bath lubrication with an easy-view sight glass simplifies daily checks and supports continuous-duty operation.

Benefits

Why Professionals Choose It

• Hot-water capable: Rated up to 185°F for faster degreasing, sanitation, and heavy soil removal.
• Extreme pressure: 5,000 PSI for restoration, stripping, and industrial surface preparation.
• Productive flow: 4.0 GPM supports strong rinsing and efficient coverage.
• Low-RPM durability: Reduced wear and longer component life at 1,450 RPM.
• Flexible integration: 24mm solid shaft works with many belt-drive and direct-couple configurations.
• Service-friendly: Sight glass and vented dipstick make maintenance faster and more consistent.

Typical Applications

Best-Fit Use Cases

• Industrial degreasing and heavy equipment cleaning.
• Food and dairy facility sanitation (hot-water washdown environments).
• Contractor trailer rigs and commercial hot-water skids.
• Agricultural washdown stations and barn cleaning.
• Surface preparation: paint prep, graffiti removal, restoration work.
• Municipal and public works hot-water cleaning systems.

Installation & Maintenance Notes

Best Practices

• Confirm belt alignment/coupling alignment to protect bearings and seals under high-pressure loads.
• Use filtered inlet water and adequate supply volume to reduce cavitation risk.
• Match nozzles/orifices to the pump’s flow and pressure capability and verify with a pressure gauge.
• Flush with clean water after detergents/chemicals, especially in hot-water systems.
• Check oil level through the sight glass before each use and follow recommended break-in and service intervals.

Summary

• The SXW15.35HT is a hot-water-rated triplex plunger pump delivering 4.0 GPM at up to 5,000 PSI at 1,450 RPM, rated to 185°F for professional hot-water cleaning systems.
• With a 24mm solid keyed shaft, ceramic plungers, stainless valves, and easy oil monitoring, it’s built for demanding commercial and industrial duty cycles where heat and uptime matter.
