HMS-7-2 Pneumatic Liquid Booster Pump for Industrial Equipment

Bring air-driven liquid pressurization into your equipment design with the HMS-7-2 pneumatic liquid booster pump. This model has a maximum rated output pressure of 1,800 psi (124 bar) and a displacement of 9.8 mL per cycle. Its maximum permitted air supply pressure is 150 psi.

For OEM buyers and system integrators, the HMS-7-2 offers defined performance limits and connection sizes for component selection. Whether you are planning a new assembly or reviewing a replacement pump, these details provide a clear starting point for your technical specification.

Plan Your Pressure Circuit Around Defined Ratings

A pump must match both the pressure target and the liquid delivery needs of the equipment. The HMS-7-2 is rated to a maximum of 1,800 psi for both continuous and intermittent duty. Therefore, buyers can use the same published pressure limit when reviewing either operating pattern.

However, pressure capacity alone does not establish flow performance. The listed 9.8 mL displacement describes the liquid volume moved per cycle. Actual flow also depends on cycle speed and working conditions.

For this reason, specify the flow needed at your intended outlet pressure when requesting a quotation. This helps connect pump selection with the cycle time or liquid supply rate your process requires.

HMS-7-2 Performance and Connection Data

The following data applies specifically to the HMS-7-2 model.

These values are taken from the HMS-7-2 row of the product parameter table. The maximum air supply pressure and maximum output pressure are separate limits; neither should be exceeded.

Match the Pump to Your Equipment Duty

The HMS-7-2 can be assessed for liquid pressure circuits in test equipment, machinery, and industrial assemblies. Final suitability depends on the fluid, temperature, pressure, flow, and operating schedule.

Potential project requirements include:

• Pressure test assemblies: Review the test pressure, fill volume, and required cycle time together.

• Machine-mounted liquid circuits: Check the pressure and delivery needed by the connected equipment.

• Equipment upgrades: Compare the existing pump’s working duty, ports, and installation dimensions before selecting a replacement.

In each case, confirm the wetted materials and seals against the working liquid. Fluid compatibility cannot be established from pressure ratings alone.

Check Air and Liquid Connections Separately

The HMS-7-2 uses a G 3/8" air-drive connection, while its liquid ports are 3/4" FNPT at the inlet and 1/2" FNPT at the outlet. Since these ports have different thread designations, each connection needs its own fitting check.

Start with the available air supply. Confirm both its pressure and its capacity to support the intended operating duty. Next, review the liquid inlet arrangement and outlet pipework.

Also, select hoses, valves, gauges, and fittings to suit the system’s pressure and fluid conditions. This supports a complete assembly specification before purchasing begins.

Questions Buyers Ask About the HMS-7-2

What is the maximum output pressure?

The published maximum rated output is 1,800 psi, or 124 bar, for both continuous and intermittent operation.

Does 9.8 mL per cycle mean 9.8 mL per minute?

No. It is a displacement value for each cycle. A flow rate requires cycle speed and operating conditions to be considered as well.

Can the pump handle any industrial liquid?

Compatibility needs confirmation for the specific fluid and temperature. Provide the liquid name, concentration where relevant, and operating temperature during the selection review.

What should an OEM buyer confirm before ordering?

Confirm operating performance, fluid compatibility, installation dimensions, connection details, and the items included in the supply scope.

Send Your HMS-7-2 Project Requirements

For a useful quotation, send us your target pressure, required flow, working liquid, available air supply, and operating schedule. In addition, include the order quantity, delivery destination, and required delivery date.

For equipment integration, a circuit diagram or installation drawing can help clarify the application. State HMS-7-2 as the requested model so the quotation and technical review refer to the correct configuration.
