Troubleshooting: match the symptom to the likely part

Enerpac's instruction sheets list these causes for the most common pump problems.

Symptom	Causes Enerpac lists	Parts that may be involved
Cylinder does not advance or advances slowly	Low oil level, release valve open, loose couplers, air in the system	Release or relief valve, couplers
Cylinder advances but will not hold pressure	Leaking connections or seals, internal pump leakage	Seals, O-rings, check valves, seal kit
Cylinder will not retract	Overfilled reservoir, loose couplers, air in the system, blocked flow	Couplers, valves
Electric pump stops or shows an alarm	Thermal overload or protection device tripped	Motor, power board, electrical components

Hydraulic equipment should be serviced by a qualified hydraulic technician, as Enerpac's instructions state.

Keep your pump running longer

Use Enerpac hydraulic oil. Enerpac's instruction sheets call for Enerpac oil to protect pump life and the warranty. See Enerpac Hydraulic Oil.
Change the oil on schedule. Enerpac's hand pump instructions say to drain and refill with clean oil every 12 months, and more often in dirty environments. Electric pump manuals set intervals in operating hours; the SFP split-flow pump, for example, calls for draining the reservoir and replacing the filter every 250 hours. Check your pump's instruction sheet for its interval.
Check the oil level before each use, and fill only to the level mark.
Keep dirt out. Screw dust caps onto couplers whenever they are disconnected. Enerpac warns that dirt in the system can cause pump, cylinder and valve failure.

Finding the right part number

Find the model number on your pump's nameplate.
Look up the repair parts sheet for that model; it lists every part by number and position.
Match that part number to our listing. Some parts changed between production versions, so if anything does not match, call (704) 463-1070 before ordering.
