Single-acting hydraulic hand pumps
A single-acting hydraulic hand pump operates a cylinder that moves hydraulically in one direction. The return movement relies on load, gravity or spring force, through a suitable return or lowering arrangement. Choose the pump that suits your cylinder, connections and oil supply.
Which configuration suits your installation?
Hand pump without a tank
For installations with a separate oil reservoir. Compare mounting and oil connections: a tank-mounted pump and an inline pump are not connected in the same way.
Compare the pump models shown above for your selected delivery country and check the required reservoir arrangement for each model.
Hand pump with an oil tank
A model with a tank combines pump and reservoir. Choose suitable displacement and sufficient usable oil capacity for your cylinder. Check installation orientation and handle clearance too.
Tank capacity and pump displacement are separate choices; a larger tank does not automatically mean more oil per pump stroke.
BSP or NPTF connections
The range includes different connection types. Check not just the nominal inch size but also the thread type and sealing method on the product page.
A 3/8″ BSP connection and a 3/8″ NPTF connection are not interchangeable.
How to choose a suitable single-acting hand pump
- Cylinder and return function: check that your cylinder is single-acting and how retraction and oil return are arranged.
- Pump displacement: compare the stated oil volume per pump stroke. This affects the number of handle movements needed for the cylinder stroke.
- Working pressure: check the permitted pressure of the selected pump variant as well as the cylinder, hoses and couplings. Do not assume all variants have the same maximum pressure.
- Oil capacity: match usable tank capacity to the oil needed over the cylinder's full stroke, while maintaining the specified oil level.
- Connections and mounting: compare pressure and any suction connections, fixing dimensions, permitted orientation and handle clearance.
- Package contents: check whether the tank, handle, suction tube and filter are included with the chosen model.
Applications and cylinder selection
A hand pump is practical for occasional use, maintenance and suitable lifting or tipping functions without a fixed power supply. Suitability for your machine, trailer or workshop installation depends on pressure, oil requirements, mounting and controls.
Choosing a new cylinder too? Compare our single-acting hydraulic cylinders. If your cylinder needs hydraulic power in both directions, see the hand pumps for double-acting cylinders and check the associated valve function.
Choosing an oil tank or extending existing manual operation
A pump without an integral tank needs a suitable oil supply. View the oil reservoirs for hydraulic hand pumps and check mounting and connections against your pump. A separate tank cannot simply be connected to every hand pump.
This collection also includes a hydraulic pump kit for cordless drill drive. This is a conversion option for a compatible tipping trailer, not a conventional hand pump. Check the specifications and connection to your existing installation before choosing it.
Frequently asked questions about single-acting hand pumps
How does the cylinder return with a single-acting hand pump?
The cylinder returns under load, gravity or spring force, for example. Oil must be able to flow back through a suitable return or lowering arrangement. Check how this function is implemented in your pump and installation.
Can a double-stroke hand pump operate a single-acting cylinder?
Yes, if designed for that purpose. Double stroke means the pump delivers oil during both handle movements. It does not by itself mean the connected cylinder is double-acting.
How do I choose between different pump displacements?
Compare the specified oil volume per stroke with your cylinder's oil requirement. A larger displacement can reduce the number of pump strokes needed. Also check the maximum working pressure and operating specifications of that variant.
Are all 3/8-inch connections the same?
No. Nominal size alone is not enough. Compare BSP or NPTF, male or female threads and the specified sealing method. Use only fittings confirmed to suit the pump.
