TROUBLE SHOOTING YOUR HYDRAULIC SYSTEM
PROBLEM POSSIBLE CAUSES REMEDY
Failure of pump to Low fluid level in reservoir Add recommended oil and
deliver fluid check level to be certain pump
suction line inlet is submerged
deeply enough to prevent air
entering directly or by the
formation of a vortex.
Oil intake pipe or strainer Clean or replace
plugged
Air leak in suction line, prevent Repair leaks
priming or causing noise and
irregular action of control circuit
Oil viscosity too heavy to pick Use lighter viscosity oil or
up prime (especially in cold install a low density immersion
weather) heater (with steel element only)
Wrong direction of rotation Must be reversed to prevent
damage to pump
Broken pump shaft or parts Replace
broken inside pump
Pump making a noise Intake line, suction filter of pipe Clean intake, filter or eliminate
restricted restriction. Be sure suction
line is completely open
Air leaks
1) At pump intake piping joints 1) Tighten as required
2) At pump shaft packing (if 2) Repair or replace
present) or seals
3) Air drawn in through inlet 3) Be sure suction and return
pipe opening lines are below oil level in
reservoir
Reservoir air vent plugged Air must be allowed to breathe
in the reservoir. Clean or
replace reservoir breather .
Too high oil viscosity Use lower viscosity oil. Check
recommendations in start-up
information
Coupling misalignment Re-align
Worn or broken parts Replace
