Description

This double-acting hydraulic hand pump operates a suitable hydraulic cylinder manually in both directions, without an electric or engine drive. Choose 12 cc, 25 cc or 45 cc. It is intended for intermittent or emergency operation.

DOUBLE-ACTING • 12 / 25 / 45 CC • G3/8 BSP

The two G3/8 BSP pressure ports supply the two sides of a double-acting cylinder according to the control position. Match the pump, working pressure and oil capacity to the complete installation.

Compare the three models

12 cc

SPH390155
Maximum working pressure: 380 bar

25 cc

SPH390157
Maximum working pressure: 350 bar

45 cc

SPH390159
Maximum working pressure: 280 bar

A larger cc value provides a greater stated oil displacement, but this series also has a lower maximum working pressure as displacement increases. Check the pressure ratings of the cylinder, hoses and other components before choosing.

Operation and applications

This pump is intended for manual operation of a double-acting hydraulic cylinder. The directional control determines which cylinder chamber receives oil and allows oil from the other chamber to return. Check the pressure protection required by your complete system.

See our double-acting hydraulic hand pumps for other models. If your cylinder only needs hydraulic power in one direction and returns under load or spring force, compare our single-acting hydraulic hand pumps.

Oil reservoir and installation

Separate oil reservoirs for hydraulic hand pumps in 3 and 5 litre sizes are available for this series. Reservoir capacity differs from pump displacement. Choose usable oil capacity to suit your cylinder and installation; check the flange, fixing dimensions and permitted mounting position.

The pump has a cast-iron body, a lapped and chrome-plated steel pump rod and a steel lever with a plastic grip. Allow sufficient clearance for lever movement and connections.

Frequently asked questions

Which model should I choose?

Compare both required oil displacement and working pressure. The maximum working pressures are 380 bar for 12 cc, 350 bar for 25 cc and 280 bar for 45 cc. Do not choose solely by the largest cc value.

What does double-acting mean here?

The pump is intended for a suitable system that hydraulically extends and retracts a double-acting cylinder. The two pressure ports are labelled Outlet 1 and Outlet 2 in the drawing. This differs from merely pumping oil during both lever movements.

Which connections does the pump have?

The two pressure ports are G3/8 BSP. The inlet is marked Ø9 mm in the drawing. Compare threads, sealing and connections with the other components.

Is an oil reservoir included?

This product group contains the 12 cc, 25 cc and 45 cc pump models. Select a separate reservoir independently. Tanks of 3 and 5 litres are available for this series; check mounting and required usable oil capacity.
