SHPA4G70HN | 4 GPM 7000 PSI Pump 1450 RPM SHPA Series Duty

SHPA4G70HN Super High-Pressure Industrial Pump

The SHPA4G70HN Super High-Pressure Industrial Pump is engineered for demanding applications that require consistent, reliable, and extremely high-pressure output. Built as part of the SHPA Series (194 SHP), this industrial-grade triplex plunger pump delivers exceptional performance in environments where durability and precision are critical. With a maximum output of 4 gallons per minute (GPM) and an impressive pressure rating of up to 7,250 PSI (500 bar), this unit is designed to handle the toughest cleaning, blasting, and testing tasks.

Operating at a low speed of 1,450 RPM, the SHPA4G70HN minimizes vibration, reduces heat buildup, and extends the lifespan of internal components. This makes it ideal for continuous-duty industrial use where uptime and reliability are essential. Its horizontal pump orientation and compact 29 lb design allow for easy integration into a wide range of systems, including skid-mounted units, trailers, and fixed installations.

Construction and Design

The SHPA4G70HN is built with high-quality materials to ensure long-term durability under extreme pressure conditions. The pump head is constructed from nickel-plated brass, providing excellent corrosion resistance and strength. Internally, aluminum connecting rods contribute to reduced weight while maintaining structural integrity and efficient motion transfer.

Its triplex plunger design is a key feature, utilizing three precision-engineered plungers that operate in sequence. This configuration reduces pulsation in the water flow, ensuring smoother pressure delivery and improved system performance. The hardened plungers are designed to withstand high stress and resist wear, even during prolonged use in harsh environments.

The solid 27 mm shaft enhances torque transmission and stability, while the neutral shaft configuration allows for flexible integration with various drive systems. Combined with heavy-duty internal components, the pump maintains consistent performance even under continuous high-load conditions.

Performance and Efficiency

One of the standout features of the SHPA4G70HN is its ability to deliver ultra-high pressure while operating at a relatively low RPM. Running at 1,450 RPM significantly reduces mechanical stress, vibration, and heat generation compared to high-speed pumps. This not only extends component life but also improves lubrication efficiency and overall system reliability.

With a flow rate of 4 GPM, the pump provides an optimal balance between water volume and pressure. This makes it highly effective for precision cleaning, surface preparation, and hydrostatic testing, where both force and control are required. The pump’s design ensures consistent pressure output, even during extended operation, making it suitable for demanding industrial workflows.

Applications

The SHPA4G70HN is specifically designed for heavy-duty industrial applications. Its high-pressure capability and durable construction make it suitable for a wide range of uses, including:

• Hydrostatic and pressure testing systems
• Industrial surface preparation and coating removal
• High-pressure cleaning and descaling
• Shipyard and offshore maintenance operations
• Construction and infrastructure cleaning
• Manufacturing equipment maintenance

These applications often require equipment that can perform reliably under extreme conditions, and the SHPA4G70HN is designed to meet those demands with ease.

Installation and Integration

The pump’s horizontal configuration and compact footprint make it easy to install in a variety of setups. It can be integrated into mobile systems such as trailers or skid units, as well as permanent industrial installations. The standard inlet and outlet port sizes (1/2″ and 3/8″ respectively) allow for straightforward connection to existing plumbing and high-pressure systems.

For optimal performance and longevity, it is recommended to pair the pump with proper filtration systems, pressure relief valves, and cooling or recirculation components. These additions help protect internal seals and maintain consistent operating conditions, especially during prolonged use at maximum pressure.

Maintenance and Serviceability

The SHPA4G70HN is designed with serviceability in mind. Its 32 oz oil capacity ensures adequate lubrication for internal components, while accessible design elements make routine maintenance straightforward. Regular oil checks and changes, along with proper system monitoring, will help maximize the pump’s lifespan and maintain peak performance.

The use of durable materials such as nickel-plated brass and hardened plungers reduces the frequency of repairs and replacements. This results in lower overall maintenance costs and increased uptime for industrial operations.
