The Enerpac P80 is a two-speed, all-steel ULTIMA hydraulic hand pump that builds 10,000 psi and holds 134 in³ of usable oil. It is Enerpac's hand pump for 25- to 100-ton single-acting cylinders, including the RC506, and it is the pump supplied in the SCR506H set and the IPH5031 50-ton press.

What it works with
- Cylinders: single-acting cylinders up to about 134 in³, including the RC506 (69.03 in³) and RC2514 (73.52 in³), and the RCH603 hollow cylinder.
- Sets built on the P80: SCR506H, SCR2514H, SCL1002H, SCH603H and SCH1003H.
- Presses: the IPH5031 50-ton and IPH2531 25-ton H-frame presses use the P80.
- Hose: HC7206 with CH604 coupler. Gauge: GA45GC.
- Oil: LX101 hand pump oil.
- Foot operation: the PC11 kit converts the P80 to foot power.
Features
- First stage moves 1.00 in³ per stroke to bring the plunger to the load quickly
- Lower handle effort (77 lb) than smaller single-speed pumps
- Vent-free reservoir, so no spills
- All-steel construction with chrome-plated plunger and wiper
- Built-in reservoir over-pressurization protection
How fast will it move my cylinder?
On an RC506, the first stage advances the plunger about 1 in every 11 strokes until the load is met. Under load, the second stage takes about 74 strokes per inch, so a full 6.25 in stroke under load is several hundred strokes. For repeated full-stroke work, an electric pump is the better choice; the IPE5005 press pairs the RC506 with a PUJ1200B electric pump.
P80 or another pump?
The P84 is the same pump with a 4-way valve for double-acting cylinders. The P801 holds 250 in³. The P462 holds 453 in³ for very large cylinders. For 10- to 25-ton cylinders, the lighter P392 is usually enough.
Questions about the P80
Will the P80 fully extend an RC506?
Yes. The RC506 needs 69.03 in³ for its full 6.25 in stroke, and the P80 has 134 in³. The P392 (55 in³) cannot.
Is the P80 single speed or two speed?
Two speed. It moves 1.00 in³ per stroke below 500 psi and 0.15 in³ per stroke from there to 10,000 psi.
Can the P80 run a double-acting cylinder?
No. Use the P84, which has a manual 4-way valve.
