Pump runs excessively.
Pump speeds up or runs erratically.
Pump runs, but output is low.
Lubricant leaking from safety unloader
valve.
Lubricant leaking from weep hole in vent
valve.
Possible cause
No hydraulic power to pump.
No pressure on gauge:
• Closed supply line shut off valve.
• No power to solenoid valve.
• Faulty solenoid.
• Pressure reducing valve is set too low.
• Insufficient hydraulic fluid supply.
Pressure is shown on gauge on pump
manifold:
• Closed fluid outlet line.
• Flow control valve is fully closed.
• Pump is stalled due to grease back
pressure.
Pump is seized or damaged.
Pump tube malfunction.
Outlet check damage or contamination.
Vent valve damage or contamination.
System component leaking.
Vent valve not receiving proper pressure to
keep it closed.
Injector bypassing.
Low level of grease or reservoir is empty.
Follower plate is stuck and separated
from grease.
Pump piston or checks are worn.
Insufficient hydraulic fluid supply.
Inlet pressure too low.
Faulty inlet or discharge check valve in
pump.
Pressure of system set too high.
Safety unloader damaged or contaminated.
Vent valve lubricant seal damaged.
