GeNerAL NOTeS:
1. Do not pump liquids containing metal fines.
2. Orient the discharge port to either 12 or 9 o’clock position.
3. if magnets decouple, stop the pump immediately. The rare
earth magnets used in this pump are more resistant to
demagnetization than ceramic magnets, but operating the
pump with the magnets decoupled will eventually weaken
the magnets.
4. Plastic pumps will expand and contract with temperature so
periodically check and hand-tighten screws. This pump is
designed to accept an o-ring on the discharge flange and inlet
chamfer as a backup to the NPT or BSP threads to ensure
leak-free operation after temperature cycling.
5. Fitting o-rings on discharge flange and inlet chamfer is possible.
NO DiSCHArGe
1. Air leaks in suction piping.
2. Pump not primed.
3. Discharge head too high.
4. Suction lift too high or insufficient NPSHA. Suction lift should
be 2 feet above NPSHr.
5. Closed valve.
6. Viscosity or specific gravity too high (magnets uncoupled).
iNSUFFiCieNT DiSCHArGe
1. Air leaks in suction piping.
2. Discharge head higher than anticipated.
3. Suction lift too high or insufficient NPSHA. Suction lift should
be 2 feet above NPSHr.
4. Clogged suction line, foot valve or crimp in hose.
5. Foot valve too small.
6. Foot valve or suction opening not submerged enough.
7. incorrect pump rotation.
iNSUFFiCieNT PreSSUre
1. Air or gasses in liquid.
2. impeller diameter too small.
3. Discharge head higher than anticipated.
4. incorrect pump rotation.
LOSS OF PriMe
1. Leaking suction or discharge line.
2. Suction lift too high or insufficient NPSHA. Should be 2 feet
above NPSHr.
3. Air or gasses in liquid.
4. Foreign matter in impeller.
5. Leaking valve.
exCeSSiVe POWer CONSUMPTiON
1. System head lower than rating. Pumps too much liquid.
2. Specific gravity or viscosity of liquid pumped is too high or
higher than that defined in application.
3. Binding pump parts.
