SHPA Series is a precision-engineered pump designed for industrial professionals who need consistent ultra-high pressure in their operations. Delivering up to 7,250 PSI at 4.0 GPM, this model is purpose-built for surface preparation, pipeline cleaning, cutting, and other extreme-duty applications.
Built with a nickel-plated brass manifold, stainless steel valves, and aluminum connecting rods, the SHPA is designed to withstand corrosion, heat, and the relentless stresses of continuous operation.

Performance at a Glance

The SHPA strikes a balance between manageable flow and extreme pressure, making it ideal for jobs where force—not volume—is the top priority.

• Flow Rate: 4.0 GPM (15.1 L/min)
• Pressure: 7,250 PSI continuous rating
• RPM: 1750 (smooth and controlled operation)
• Oil Capacity: 32 oz
• Construction: Nickel-plated brass head, ceramic plungers, stainless valves, and aluminum connecting rods
• List Price: $2,573.16

Key Features

• Nickel-Plated Brass Manifold → Superior resistance to oxidation and chemicals compared to standard brass.
• Solid Shaft (24mm) → Built for pulley-driven or direct-coupled electric motor setups.
• High PSI Output → Capable of reaching 7,250 PSI, one of the highest ratings in AR’s industrial pump line.
• Service-Friendly Design → Backed by comprehensive repair kits and easy field maintenance.
• Compact & Efficient → Moderate footprint allows integration into industrial skids, trailers, and fixed cleaning stations.

Applications

The SHPA Series is designed for specialized high-pressure uses where traditional pumps cannot compete:

• Pipeline Cleaning & Hydrostatic Testing → Critical for oil, gas, and municipal infrastructure.
• Steel & Concrete Surface Preparation → Removes coatings, paint, and rust without abrasive blasting.
• Shipyards & Marine Industry → Strips hull coatings, cleans heavy marine buildup, and supports vessel maintenance.
• Industrial Cutting & Precision Jetting → Assists in waterjet-style cutting for stone, composites, and metals.
• Municipal & Government Operations → Used in bridge cleaning, graffiti removal, and sewer jetting.
• Heavy Industry & Manufacturing → Keeps machinery, tanks, and production facilities free of residue and buildup.

Benefits to Operators

• Extreme Pressure Reliability → When you need consistent 7,250 PSI, SHPA delivers.
• Low Flow for High Impact → Perfect balance for cutting and surface prep tasks.
• Longevity & Serviceability → Rebuild kits make this pump an investment, not a consumable.
• Chemical & Corrosion Resistant → Nickel-plated manifold withstands industrial conditions.
• Trusted Global Brand → Backed by AR’s reputation for Italian engineering and decades of pump innovation.

Why Choose the SHPA?

The SHPA isn’t for light-duty or general-purpose jobs—it’s engineered for industries where only the toughest equipment survives. If your operation involves coatings removal, cutting, or extreme-duty washing, this pump provides the muscle and endurance to do it reliably.

• Focused Design → Built specifically for ultra-high pressure.
• Rebuildable → Keep it running for decades with available parts.
• Proven Performance → In use globally across energy, marine, and infrastructure sectors.
• Smart Investment → High upfront value, but lower long-term cost due to serviceability.

Conclusion

The AR SHPA Series is a workhorse for high-pressure, low-flow industrial cleaning and cutting tasks. Compact yet powerful, it represents the best of AR’s engineering for operators who need consistent pressure, reliability, and durability.
Whether you’re cleaning pipelines, prepping steel, stripping marine coatings, or supporting industrial cutting systems, the SHPA pump ensures that when extreme pressure is the mission, downtime is not an option.
