What’s Included with RGX1550HN

Factory-assembled industrial pump package

• Nickel-plated manifold and body for superior resistance to corrosion in harsh,
  chemical-heavy, or marine environments.
• Heavy-duty triplex plunger system designed for consistent ultra high-pressure output.
• High-quality seals and valves engineered for leak-free operation at extreme pressures.
• 24 mm drive shaft for seamless integration with industrial belt-drive setups and
  other external drive systems.
• Optimized internal flow channels to maximize efficiency and maintain rated
  PSI/GPM performance.

How the Pump Works

Triplex ceramic plungers with corrosion-resistant body

• A triplex plunger design uses three ceramic plungers to pressurize water to
  7,250 PSI, delivering a concentrated, ultra high-pressure jet for demanding tasks.
• Operating at a steady 1,450 RPM, the pump balances extreme power with reduced
  wear, minimizing vibration and mechanical stress while maintaining consistent output.
• The nickel-plated exterior adds a robust protective layer, making the pump
  suitable for high-humidity, saltwater, and chemical-exposure environments.

Benefits of RGX1550HN

Extreme pressure, protection, and longevity

• Ultra high pressure: Generates up to 7,250 PSI, capable of handling the toughest
  industrial cleaning, cutting, and testing applications.
• Corrosion resistance: Nickel-plated body provides added protection in harsh,
  chemical-rich, or marine environments.
• Continuous-duty design: Built to withstand long operating hours under
  extreme conditions with minimal downtime.
• Durable construction: Premium materials resist wear, abrasion, and chemical attack
  for long service life.
• Efficient operation: Maintains steady performance at 1,450 RPM, helping reduce
  heat buildup and extend component life.
• Versatile implementation: Integrates easily into belt-driven and industrial
  drive systems for a wide range of applications.

Typical Applications

Industrial, marine, and testing environments

• Hydrostatic testing: Verifies the strength and safety of pipelines, tanks,
  and pressure vessels under high-pressure water.
• Water jetting and cutting: Removes coatings, heavy deposits, and industrial buildup,
  and supports specialized cutting processes.
• Marine and shipyard work: Handles saltwater exposure and aggressive marine
  washdown tasks.
• Industrial cleaning: Cleans machinery, oilfield equipment, process skids,
  and construction gear in harsh environments.
• Chemical processing plants: Nickel plating provides extra protection where
  harsh detergents and cleaning agents are used.
• Surface preparation: Prepares concrete, structural steel, and industrial surfaces
  prior to coating, lining, or refinishing.
