VEVOR Air Hydraulic Foot Pump, 10,000 PSI: features, specs and uses

The VEVOR air hydraulic pump is a foot-operated treadle pump that uses compressed air to drive hydraulic oil to a ram, press or puller. It is aimed at workshops that already run an air line and want to keep both hands free while a hydraulic tool works, for example on auto body frame machines and pulling posts.

How an air-over-hydraulic pump works

Instead of pumping a handle by hand, an air hydraulic pump uses compressed air to move a piston that pressurises the oil. VEVOR describes this one as foot-actuated: you press the treadle to apply pressure and let it rebound to release it. The advantage is that your hands stay on the work or the tool while the pump does the effort.

An air supply is therefore part of the setup. The pump has a 1/4 inch NPT inlet for the air line, and VEVOR includes an air inlet adapter and PTFE tape for sealing the threaded connections.

What 10,000 PSI means

The listing says the pump suits rams, presses and hydraulic pullers that operate at pressures of up to 10,000 PSI. That figure is the pump's working pressure limit. The force a connected ram delivers also depends on its piston area, so the same pressure produces more force on a large ram than a small one. Always check that every component in the circuit, including hose, coupler and ram, is built for that pressure.

VEVOR also lists an internal relief valve intended to protect hydraulic components.

Single-acting rams only

The listing specifically names single-acting ram applications. A single-acting ram is pushed out by oil pressure and returns by spring or load once pressure is released. A double-acting ram needs oil routed to both sides and a different pump and valve arrangement, so this pump is not described for that use.

Oil capacity and reach

The oil reservoir holds 98 cubic inches, which is about half a US gallon (roughly 1.6 litres). A larger reservoir helps when a ram has a long stroke or a circuit takes a lot of oil. VEVOR says the pump arrives with hydraulic oil already inside, so it can be used straight from the box.

The oil outlet is 3/8 inch NPT, and a 6.6 ft (2 m) oil pipe is included, letting the pump sit away from the ram. A hydraulic coupler is also supplied. Check that its fitting matches your ram's before you plan the circuit.

Build and mounting

VEVOR says the pump core is aviation-grade aluminum inside a metal shell. Two screw holes at the base allow it to be fixed to a bench or floor, which the company says reduces sliding and vibration in use. The pump measures about 10.3 x 5.4 x 7.3 inches and weighs 19.6 lb (about 8.9 kg).

Who it suits

It suits auto body shops using frame machines or pulling posts, as well as workshops and construction settings that run single-acting rams, presses or pullers from an air line. It is a component, not a complete tool, so it only makes sense alongside a ram or puller that matches its pressure limit and fittings.

What to check before you buy

• Air supply: confirm your compressor and air line can feed a 1/4 inch NPT inlet, and check the required air pressure in the manual.
• Ram type: it is described for single-acting rams.
• Pressure limits: make sure your ram, hose and fittings all match 10,000 PSI.
• Thread sizes: compare the 3/8 inch NPT outlet and the supplied coupler with your equipment.
• Mounting: plan where to bolt it down and where the hose will run.
• Upkeep: check the manual for oil type, topping up and checking for leaks.
