The HF-151 pneumatic liquid booster pump provides air-driven liquid pressurization with a maximum rated output of 25,000 psi (1,724 bar). Its published displacement is 4.4 mL per cycle, and its discharge connection is designated 1/4-inch HP.

For specialist equipment builders and industrial buyers, the HF-151 offers a defined combination of pressure capacity, displacement, and connection sizes. Both continuous and intermittent operation carry the same listed maximum output pressure.

Specify this model for application review when your liquid pressure system requires performance within these published limits.

High-Pressure Capability for Specialist Equipment Projects

Selecting a pump for a high-pressure assembly starts with the required operating pressure and the liquid volume needed at that pressure. The HF-151’s 25,000 psi rating establishes its maximum rated output, while its displacement provides a separate reference for delivery planning.

Potential project evaluations include component pressure test benches, laboratory pressure equipment, and industrial liquid pressure packages. Suitability depends on the working fluid, temperature, required flow, and operating sequence.

For example, a test assembly may have distinct filling and pressurization stages. Therefore, include the volume and time requirements for each stage when submitting the application. This gives the technical review a clearer picture of the complete duty.

A Dedicated HP Outlet for the Discharge Circuit

The HF-151 uses a 1/4-inch HP outlet, while the air-drive and liquid inlet ports are both 1/2-inch FNPT. These designations should appear separately in the equipment connection schedule.

Before selecting discharge fittings, confirm the HP connection details against the product drawing. The listed size alone does not establish the complete mating geometry.

Also, review the pressure rating and fluid compatibility of the downstream tubing, valves, gauges, and other components. Each part must suit the intended system conditions.

On the supply side, confirm the liquid inlet arrangement and available compressed-air capacity. The maximum permitted air supply pressure is 150 psi.

Understanding the 4.4 mL Displacement

The HF-151 has a listed displacement of 4.4 mL per cycle. This describes liquid volume per cycle; it is not a flow rate per minute.

Actual flow depends on operating conditions, including cycle speed, outlet pressure, air supply, and inlet conditions. Consequently, buyers should specify the required delivery at the intended working pressure.

If cycle time matters to your process, provide the target time as well. Request operating data for that duty point so equipment planning is based on the application’s needs.

Define the Configuration Before Purchase

For OEM projects, include the HF-151 model reference in the equipment specification. Then confirm the wetted materials, seals, operating temperature range, dimensions, and mounting details.

Fluid compatibility requires a specific review. Provide the liquid name and concentration where relevant, together with the operating temperature.

In addition, define the supply scope during quotation. Identify any required accessories, connection components, drawings, manuals, or other documentation. For replacement orders, include the existing pump reference and installation details to support a complete comparison.
