IMPELLER CLEARANCE
WARNING!
Check impeller clearance prior to starting
pump. Setting may have changed during
transit.
WARNING!
Lock out power prior to working on pump.
Impeller clearance is the measurement between the impeller vanes and the surface of
the casing. This clearance is set at .015 inches during assembly, but may need to be
adjusted before initial startup. (See APPENDIX A for detailed procedures on setting
the impeller clearance.)
PRIMING
Prior to starting a centrifugal pump, it is imperative that you prime the pump by
flooding the suction piping and casing with fluid. Priming will occur when you open
the suction isolation valve and the packing sealing liquid valve.
CAUTION!
Do not operate the pump without liquid in
the casing.
