Troubleshooting

Problem

Cause

Solution

Pump is not operating. No lubricant flow.

No air

1.

Adjust air pressure/supply.

2.

Open bleed-type master air valve (F) 
(page 5 and 6).

Pump is operating. No lubricant flow.

No lubricant in reservoir

Fill the reservoir.

Losing prime

1.

Remove trapped air (see Priming, 
page 10).

2.

Prime pump.

Injectors not cycling or only some of the 
injectors are operating

No lubricant flow

See Pump is not operating. No lubricant 
flow in Troubleshooting table.

Low pressure or no pressure

1.

Check piping for leaks. If a leak is 
detected, repair or replace piping.

2.

Check injectors for leaks. If a leak is 
detected, repair or replace injector.

3.

If the pressure relief valve is set 
below the injector firing pressure, the 
injector will not operate. See page 11 
for pressure relief setup instructions.

4.

Check vent and relief valve o-rings. 
Damaged/worn o-rings will not allow 
pump to reach full pressure.

Pump seals are bad

Replace seals. See Parts, page 18 
and 20. 

Divider valve not cycling

No lubricant flow

See Troubleshooting, Pump is not oper-
ating.

Low lube point pressure or no pressure

See Troubleshooting, Pump is not oper-
ating.

Check valve block for leaks.

Check valve block for stuck pistons.

Pump seals are damaged

Replace seals.
