Troubleshooting Pump will not run or runs slowly. 1. Remove plug from pilot spool exhaust. 2. Ensure that the air inlet pressure is at least 0.4 bar (5 psig) above startup pressure and that the differential pressure (the difference between air inlet and liquid discharge pressures) is not less than 0.7 bar (10 psig). 3. Check air inlet filter for debris (see “Suggested Installation, Operation, Maintenance and Troubleshooting”). 4. Check for extreme air leakage (blow by) that would indicate worn seals/bores in the air valve, pilot spool and m ...
