The HMS-5 pneumatic liquid booster pump uses compressed air to increase liquid pressure in industrial systems. It features a single air head, an actual area ratio of 5.6, and a maximum rated output pressure of 625 psi (43 bar). Its displacement is 13.6 mL per cycle, while the maximum air supply pressure is 125 psi.
For equipment builders, system integrators, and industrial buyers, the HMS-5 provides clear specifications for pump selection. Its defined pressure rating, displacement, and threaded ports help engineers assess how it fits into a liquid pressure circuit.

Displacement per cycle describes the liquid volume moved during each cycle. It is not a flow-rate rating. Actual delivery depends on operating conditions, including cycle speed, air supply, inlet conditions, and outlet pressure.
Key Features for Industrial Buyers
625 psi rated output. The HMS-5 has the same listed maximum output pressure for continuous and intermittent duty. This gives buyers a clear pressure limit when reviewing the pump for a planned system.
13.6 mL displacement per cycle. The published displacement supports an initial assessment of liquid delivery needs. However, required flow should also be checked at the intended working pressure.
Defined FNPT connections. Separate air-drive, liquid inlet, and liquid outlet ports help engineers plan fittings and pipework. As a result, connection requirements can be reviewed early in the equipment design.
Single air-head configuration. The HMS-5 uses a pneumatic drive arrangement with a maximum air supply pressure of 125 psi. Therefore, the available plant air supply is a key part of model selection.
Applications and System Selection
The HMS-5 can be evaluated for industrial liquid pressurization tasks, such as pressure test equipment, hydraulic fixtures, and liquid supply circuits. Suitability depends on the working fluid, required pressure, target flow, and duty cycle.
For a test bench, first define the pressure needed at the test point. Then check the required fill volume and cycle time. For a liquid supply circuit, review inlet conditions and pressure losses through the pipework.
Fluid compatibility also needs confirmation before ordering. The parameter table does not list wetted materials, seal materials, or operating temperature limits. These details should be checked against the actual liquid and process conditions.
For broader model selection, review our air-driven liquid pumps.
Installation and Connection Planning
The HMS-5 has a 1/4" FNPT air-drive port, a 3/4" FNPT liquid inlet, and a 1/2" FNPT liquid outlet. Confirm the mating thread type before choosing adapters, hoses, or valves.
In addition, check the pressure rating and fluid compatibility of all connected parts. The pump’s 43 bar rating does not establish the rating of the complete assembly.
The maximum air supply pressure is 125 psi. This is an upper limit, rather than a required operating setting. Confirm the air pressure needed for the intended duty, and request operating data when flow at a specific outlet pressure is critical.
Information to Include in Your Purchase Inquiry
A detailed inquiry helps align the pump specification with your equipment. Please provide:
-
Working liquid and operating temperature.
-
Required outlet pressure and flow rate.
-
