Pneumatic Pressure Test Pump
YFQ140-J
An air-driven pressure-test pump package for applications requiring hydraulic pressure without an electric drive at the pump.
Share your application and required configuration for a project-specific quotation.
Product overview
The YFQ140-J uses compressed air to drive a reciprocating hydraulic pumping mechanism. The reference package combines low- and high-pressure pumping stages for pressure-testing applications.
The catalog describes automatic pressure holding and pressure restoration when circuit pressure drops. Available flow depends on the air supply, pressure ratio and hydraulic backpressure. Define the required duty point and test medium before selecting a package.

- Portability, recording and remote-control needs
Before you enquire
Does the pump require electricity?+
The pumping drive uses compressed air. Any optional recording, control or accessory equipment may have separate power requirements.
How should I specify the required flow?+
Provide the flow required at your target pressure, together with the available air supply. A no-load flow figure is not a substitute for the duty point.
Can this be supplied as part of a complete test package?+
List the required reservoir, valves, gauges, hoses, connections and recording functions so the quotation defines the full package.
