Troubleshooting Guide for Pumps

PROBLEM: SOLUTION:
WARNING:
THINK SAFETY FIRST!!!!
THINK SAFETY ALWAYS!!!
Your pump does not work? There
are Three Basic Problems!
Air Motor Operates but
nothing comes out.
This is the most
common problem.
Air Motor Operates;
Grease comes out but
there is no pressure.
2nd Common Prob.
Air Motor does not
operate. This is a less
common occurrence.
We will deal with all 3 of these problems and step you through a troubleshooting sequence so you can solve the problem
on your own without our intervention and be on your way. All of the pumps undergo 2 types of stringent tests at the
factory; The first is a cycle test in grease with the pump pumping a certain amount of grease per cycle over a stated time
period. The second test is a pressure test with a meter to hold grease pressure at 5000 psi at 100 psi of air pressure for a
stated period of time before they leave the factory. This ensures that your pump will work out of the box.
WARNING:
If the Air is connected to the pump, consider the pump to be live. Do not
attempt to work on the pump or the system without disconnecting the Air
Inlet and relieving pressure in the system, both air pressure and lube
pressure. Make sure there are no live air pockets in the air motor and all air
has been bled from the Air Motor before working on the pump.
WARNING: (Again!)
Ensure that all of the Air Pressure and Lubrication Pressure has been bled
out of the system and there is no Residual Lube Pressure or Air Pressure in
the System before you disassemble the pump!! (VERY IMPORTANT!!!!)
WARNING:
Do not stick your finger into the bottom of the Pump Downtube or 61275 Priming
Tube. This could result in amputation!!
WARNING:
Do not stick any type of blunt instrument into the bottom of the Pump Downtube or
61275 Priming Tube as this could ruin or bend the precision parts such as the
11723 Plunger Rod.
Question Yes No
Does the Air Motor Operate? Next Section Check In-Line Air Pressure to the pump.
Recommended Air Pressure is 80 PSI –
100 PSI.
Check Air Compressor and FRL for
obstructions or blockage
Is the Air Motor is Leaking Air? Check the Inlet Air Nipple. Use Teflon tape to seal the threads at the Air Inlet.
Silicon is not recommended since it can escape into the interior of the Air Motor
and cause damage to the valves. Check the Quick Disconnect Coupler connection
to the Air Hose. Use Teflon tape to seal the threads at the Connection
The Air Motor blows air through the
Muffler / Exhaust Port
Check to see that the Air Inlet Nipple is installed in the correct location. Check that
the Brass/Steel Plug is installed in the Air Motor head and is not leaking air. If
there are no air leaks and Air is fully engaged at least 80 psi, then sometimes in
RARE CASES the slide valve will stick in the neutral position: take the rubber part
of a mallet and lightly tap
the top of the Air Motor or the cover of the Air Motor
(41202) with the rubber part only. Did we say “LIGHTLY TAP” Yes, we did.
Don’t pound it and Don’t beat it!!! It is a casting and It will dent or Crack!
Sometimes and very rarely the slide Valve sticks in the neutral position and needs
to be prodded off of the neutral position. It also indicates that the Air Motor might
have water damage or the damage is starting or there is water present in the air
line.
Question:
Are you using a FRL
(Filter / Regulator/Lubricator)
on the pump?
Answer: We strongly suggest the use of a Filter / Regulator/Lubricator (FRL) on
the pump. The Filter should be a moisture evaporator with an automatic dump on
it so water is eliminated and purged from the air before entering the pump. If you
do not have a FRL on the pump, chances are the pump head could be
accumulating water and this will corrode the inside of the pump and moving parts,
thereby reducing the life of the pump.
Pump does not pump material Check to see if there are any blockages in the Lubricant lines. If all lines are
secure: disconnect the Grease Hose from the pump.
