Enerpac P-Series hand pumps are manual hydraulic pumps for general workshop use, driving single- or double-acting cylinders, presses, and pullers where a power source is impractical or unavailable. These low-pressure hand pumps are defined by their oil capacity, displacement per stroke, and maximum rated pressure, with single- and two-speed models matched to the cylinder and stroke length you need to move. If you are matching a discontinued model number or replacing a pump on existing equipment, send your specs for a cross-reference.

How to Choose an Enerpac P-Series Hand Pump

Match the pump to the cylinder it drives and the working pressure of the job. Confirm these specs before ordering:

Usable oil capacity (cubic inches) versus the volume your cylinder needs to complete a full stroke
Displacement per stroke and number of speeds (single-speed versus two-speed for faster low-pressure advance)
Maximum rated pressure (PSI) and whether it covers your cylinder's requirement
Single-acting versus double-acting circuit and the matching valve configuration
Port size and thread type so couplers and hose match
Handle effort and mounting style for the way the pump will be used or fixed in place

Verify the listed ratings against your application; values vary by model and should be confirmed against the manufacturer datasheet.

Which Enerpac Pump Is Right for the Job?

P-Series hand pumps are the manual option: no power required, portable, and suited to occasional or remote work. When cycle speed, repeatability, or volume make hand pumping impractical, step up to a powered pump. The Enerpac ZE-Series, Electric Hydraulic Pumps and Enerpac ZU-Series, Electric Pumps add motor-driven flow for repeated cycles. For untethered jobsite work, the Enerpac XC-Series, Cordless Hydraulic Pumps run on battery power, and the Enerpac SFP-Series, Electric Split Flow Hydraulic Pumps drive multiple cylinders in sync.

Complete the System

Build out the circuit around the pump. Add Hydraulic Quick Couplers to connect cylinders and hose without tools, and protect the oil with Hydraulic Filters. For powered setups or larger reservoirs, see Hydraulic Reservoir Tanks and Hydraulic Motors.

Cross-Referencing an Obsolete Enerpac P-Series Hand Pump

If the model number on your pump is discontinued or you are unsure which current P-Series unit matches, we can help identify an equivalent by oil capacity, pressure rating, and circuit type. Northern Hydraulics has cross-referenced hydraulic pumps and components since 1963, so send the pump tag, the cylinder it serves, and the working pressure, and we will confirm fit before you buy. Request a cross-reference.

Enerpac P-Series, Low Pressure Hand Pumps – Frequently Asked Questions

How do I size an Enerpac P-Series hand pump to my cylinder?

Compare the pump's usable oil capacity to the volume your cylinder needs for a full stroke, then confirm the pump's maximum rated pressure covers the cylinder's working pressure. If oil capacity is short of the cylinder volume, the cylinder will not fully extend on the available oil.

What specs should I check before ordering?

Check usable oil capacity (cubic inches), displacement per stroke, number of speeds, maximum rated pressure (PSI), single- versus double-acting circuit, and port size and thread type. Confirm each value against the manufacturer datasheet, since ratings vary by model.

What is the difference between a single-speed and a two-speed P-Series hand pump?

A single-speed pump moves the same oil volume per stroke throughout the cycle. A two-speed pump delivers higher volume per stroke at low pressure for faster advance, then shifts to lower volume at high pressure, which reduces the number of strokes on long-travel jobs.

Should I use a hand pump or an electric Enerpac pump?

Use a P-Series hand pump for portable, occasional, or remote work with no power source. For repeated cycles, faster operation, or higher volume, an electric pump such as the Enerpac ZE-Series, Electric Hydraulic Pumps reduces operator effort and cycle time.

Can a P-Series pump run a double-acting cylinder?

Some P-Series models are built for single-acting cylinders and others for double-acting circuits with the matching valve. Confirm the circuit type listed for the specific model against the cylinder you intend to drive before ordering.

What couplers and accessories do I need with a hand pump?

You will need hydraulic hose and Hydraulic Quick Couplers matched to the pump's port and the cylinder. Coupler thread and pressure rating must match the system to seal and connect correctly.

Are these pumps in stock?

Stock and lead times vary by model. Check the product listing for current availability, or contact us to confirm before you order.

How do I find a replacement for a discontinued Enerpac hand pump?

Send us the model number from the pump tag along with the cylinder it serves and the working pressure. We will cross-reference an equivalent by oil capacity, pressure rating, and circuit type and confirm fit before you buy. Request a quote.
