Hydraulic hand pumps

Hydraulic hand pumps in this product group

Hydraulic hand pumps in this group cover lever operated units, a foot operated model and one electrically driven pump. Most models work at a maximum pressure of 700 bar. Oil capacity ranges from 300 cm3 up to 8 litres. Housings are made of steel or aluminium alloy, depending on the series. Buyers can take a bare pump or a set already fitted with accessories. The sections below sort the range by pressure, capacity and drive method.

Manual operation uses a lever or a pedal to build hydraulic pressure. That arrangement keeps the pump usable where mains power is not available. The HC- series runs a steel housing with two speed stages at 700 bar. Its single-acting layout places supply and return on the same line. The PB- series also works in two pressure stages up to 700 bar.

Pressure ratings across the range

Pressure rating is the first filter when comparing models. Most units in this group stop at 700 bar, which serves many industrial hydraulic mechanisms. Two high pressure options go further. The aluminium housing AHP line, in the 704 and 705 versions, reaches 1000 or 1500 bar. An automatic overload relief valve protects components inside the system during operation.

The steel housing P905 set works in two pressure stages and reaches 1000 bar. Its housing is powder coated steel, and an automatic overpressure relief valve is built in. For work that stays inside the 700 bar band, the AHP 700bar model offers the same aluminium construction with two speed stages. The light alloy body keeps the pump easy to move between job positions.

Oil capacity and housing material

Oil capacity decides how much cylinder stroke the pump can feed before refilling. The P 90- series covers usable volumes from 300 to 2200 cm3. It uses a steel body, a maximum pressure of 700 bar and a single-acting design. Supply and return share one line on that layout. Smaller reservoirs suit short jobs and frequent transport between machines.

Larger reservoirs suit longer cylinder work. The HP 35 model holds up to 3500 cm3 of usable oil. Its powder coated steel housing resists dirt build-up, and paint colour varies by production batch. The HP80- model carries a nominal 8 litre tank. It exists in two lines, one for single-acting cylinders and one for double-acting jacks. Double pump versions carry the letter D after the model code.

Housing material separates two clear groups. Steel bodies appear on the HC, PB, HP and P series, with powder coating applied over the metal. Aluminium alloy bodies appear on the AHP line. The BETEX P pump combines a light design with a triangular distributor section. Its aluminium alloy oil reservoir is sealed tight, which keeps the pump flexible in changing working positions.

Sets supplied with accessories

Complete sets suit buyers starting from nothing. Each set pairs a pump with the fittings needed to connect a cylinder. The HC Set works at 700 bar and carries a usable oil volume of 1200 ml. It arrives with a gauge, hose, connectors and a case. The pump is ready for operation once the hose reaches the cylinder port.

The HC2000 SET builds on the HC-2000 pump with a 2 litre oil volume. Its package adds a gauge, hydraulic hose fittings and a metal storage box, all rated to 700 bar. The PB Set also runs at 700 bar with a steel pump body and a rubber sleeved lever. Its powder coated steel case has a latch and a carrying handle.

For an aluminium option, the AHP Set works to a maximum of 700 bar. The package holds a gauge, several connector types, a quick coupling, a hydraulic hose and a dedicated case. Sets like these remove the guesswork of matching separate fittings. They suit teams equipping a new workshop or building a second mobile kit for field service.

Foot operated and electric alternatives

Not every job leaves both hands free for a lever. The FHB- pump works at a maximum of 700 bar through a pedal. Its valve and pedal layout matches foot operation, and the body and base are made of powder coated steel. Foot drive keeps the operator's hands on the workpiece while pressure builds, which helps during alignment and positioning tasks.

Where mains supply exists and cycle counts are high, an electric unit reduces operator effort. The EP320D runs on a three phase 400 V, 50 Hz supply. Its double-acting output feeds double-acting hydraulic mechanisms. The tank holds 20 litres, with 15 litres of usable volume, at a working pressure of 700 bar, equal to 10000 psi.

How to choose and what to check

Start with the cylinder or tool you plan to drive. Confirm the pressure it needs, then match a pump rated at or above that figure. Next, compare cylinder volume against the pump reservoir so the stroke completes without refilling. Check whether the actuator is single-acting or double-acting, since that decides port configuration. Finally, decide between a bare pump and a set based on the fittings already in stock.

Weight and housing material matter for mobile work. Aluminium bodies move more easily between positions, while steel bodies with powder coating handle workshop conditions. Two-stage pumps shorten approach time by moving the cylinder quickly at low load. Overload relief valves on the AHP and P905 lines protect system components during high pressure work.
