Pump is turning but no output. |
Air in pumping chamber. |
Connect grease gun to reservoir fill point and start filling pump.
If grease takes time to start filling reservoir, air was in pump cavity.
Check reservoir over-flow tube if pump has been overfilled. If
plugged, may cause a vacuum and hold grease in reservoir.
Pumping Unit cavitating. |
Fill pump reservoir
Remove reservoir lid and clean overflow tube.
Remove pumping unit and prime by hand or remove line from pumping unit and run pump until a bubble
free flow of grease appears.
|
Reservoir empty. |
Check reservoir level.
In cold temperatures check to see if grease is suspended in top of reservoir. |
Fill
pump reservoir.
Clean out reservoir and fill with cold temperature grease or grease of lower NLGI rating.
|
Pumping unit internal check valve not working. |
Check pumping unit internal check valve by Installing 0 – 10,000 psi gauge on output of pumping
unit. Turn on pump, pressure should reach approximately 4,000 psi at pressure relief if not. |
Replace pumping unit or add external check valve. |
Rotation of pump incorrect. |
Pump is rotating clockwise. |
Reverse wires at pump controller or power supply.
|
All lubrication points are dry.
See Note: |
Pump is not working. |
Check pump operation. |
See: Pump does not work.
|
Pump off-time interval is to long. |
Pump is operating fine but to little grease is present at lube points.
|
Shorten off-time interval. |
Pump on-time interval is to short. |
Shortening off-time interval would over lubricate system. |
Lengthen on-time interval.
|
Blockage in system. |
Check for grease at pressure relief. |
Refer to leakage at pressure relief. |
Pump operating, no grease at pressure relief, all points still dry. |
Remove line at primary block inlet and attach 0-10,000 psi pressure gauge. Operate pump, if pressure does not reach 4,000 psi or relief pressure.
If pumping unit check valve is good check for leak in primary line.
|
Check pumping unit internal check valve.
Check on-time interval.
Repair leak. |
|
Note:
If lubrication points have been dry for an extended period, purge system from the by-pass zerk fitting
located on top of primary block or from top of each secondary block until sufficient grease appears at points.
|
Points are dry in one area. |
Line from primary distribution block to secondary distribution block leaking or broken. |
Remove secondary feed line and cycle pump. If no grease
present. |
Repair or replace line. |
Fitting leaking at block inlet. |
Check fittings for leakage.
|
Repair or replace fitting.
|
Single point is dry. |
Broken line. |
Check for leakage along line. |
Repair or replace line. |
Leakage at fitting. |
Look at fitting. |
Tighten or replace fitting. |
Point not receiving enough grease. |
Check integrity of line, if point is still to dry. |
Contact Beka-Max representative for help.
|
Pump rotates slowly. |
High pressure in system. |
Check pressure relief valve for grease. If no grease present,
loosen each secondary block inlet fitting one at a time. If pressure relieves
at a fitting, check individual points for restriction. |
Free up restriction at point.
|
Extremely cold temperatures. |
Check grease to see if hard. |
Clean out reservoir and fill with low temperature grease or grease of lower NLGI rating.
|
Grease coming out of pressure relief. |
Excessive pressure in system. |
Place pressure gauge in-line with pump output line. Locate
area causing high pressure. |
Repair area causing high pressure. |
Progressive distribution system has a blockage. |
If there is grease coming out of the pressure relief. Start
at the distribution block farthest from the primary block. Loosen the inlet fitting
and see if there is pressure. If there is no pressure there is no problem in
that block assembly. Work your way back to the primary block until you locate
the block with pressure at the inlet fitting. If the block has pressure, re-tighten
the inlet fitting and re-pressurize the system. Loosen each line coming from
the block. If a line has pressure when loosened the blockage is at the end of
that line. If there is no pressure at any of the lines then the blockage is internal. |
If the blockage is at the end of a distribution line, free up inlet to bearing.
If blockage is internal in the distribution block, identify and replace block segment with seized piston.
See: Trouble shooting
A series progressive distribution block.
|
Contamination in system. |
If distribution blocks are sticking repeatedly contamination may be present in system. |
Clean distribution system or replace affected lines and block assemblies.
Contact your Beka-Max representative for more options. |
Bearing point is blocked. |
Check for high pressure in system using previous step. |
Clear blockage in point.
|
Weak pressure relief valve spring. |
Place 0-10,000 psi gauge at pumping unit outlet. If pressure
relief relieves at less then 4,000 psi.
|
Replace pressure relief valve. |
