SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
A. PUMP WON’T PRIME 1. Dirty strainer screen Remove and clean strainer.
2. Suction line problem Check for leaks in suction line.
3. Pump outlet is blocked or valve is shutoff Check pump outlet system for blockage.
4. Fluid level below suction pipe Refill tank or add longer suction pipe.
5. Fluid viscosity exceeds pumps rated capability Refer to the Viscosity Charts for viscosity limits.
6. Gerotor is locked Inspect gerotor for smooth rotation. Remove any debris.
7. Excessive gerotor wear Inspect gerotor. Replace if worn.
8. Bypass valve not seating Remove / inspect bypass valve. Clean if necessary.
B. LOW FLOWRATE 1. Dirty strainer screen Remove and clean strainer.
2. Suction line problem Check for leaks in suction line.
3. Fluid viscosity exceeds pumps rated capability Refer to the Viscosity Charts for viscosity limits.
4. Nozzle or meter pressure exceeds product Replace meter or nozzle.
