Trouble Shooting Guide for Pumps ATD5217 – ATD5219 –ATD5289
PROBLEM: SOLUTION:
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.
Pump does not Operate Check In-Line Air Pressure to the pump. Recommended Air Pressure is 80 PSI
– 100 PSI.
Pump 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
Pump blows air through the
Muffler
Check to see that the Air Inlet Nipple is installed in the correct location. Check
that the Brass Plug is installed in the Air Motor head and is not leaking air.
Question:
Are you using a Filter / Regulator on the pump?
Answer:
We strongly suggest the use of a Filter / Regulator 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 Filter / Regulator on the pump, chances are the pump head could be full
of 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.
Pump operates, pumps
material but does not shut off.
Reason: Pump is not reaching stall pressure.
1: Check that all hoses, lubricant lines and controls valves are
connected and the connections are tight. There should be no leaks.
2: Check that the hoses are SAE approved Grease Hoses and made
for pumping High Pressure Grease.
DO NOT use Oil Hose or garden hose for pumping High Pressure Grease.
Air Motor on Pump operates
but no material comes out
1: Check the follower plate.
Make sure there are no air pockets in the grease underneath the follower plate.
Push down lightly on the follower plate to ensure a positive prime.
2: Check that all hoses and control valves are fully connected
3: Check to see that there are no blockages in the lines, hoses or control valves.
Pump, hoses and valves are
connected and pump does not
pump when I pull the trigger
on the control valve
