Figure 2If the water level is below “LEVEL 2”, the suctioned air rate will increase; causingpumping failure of the pump and finally the pump is put in no-load running condition.In case of this pump, however, unlike vertical submersible pumps the motor frame ofthis pump is submerged in the range from “LEVEL 1” to “LEVEL 2” so that the motor iseffectively cooled. When the water level is below “LEVEL 2”, the motor frame exposesto the atmosphere and consequently the cooling effect comes down, but it is safety withlow temperature because of its non-load run condition.2. Voltage check - during pump running; sometimes measure the power voltage tocheck that it is within the range of 95% - 105% of the specified voltage.3. Attention to pumping up of high density water where sand, slurry and other solidsare much contained in the pumping of water, the shaft power increases withincreasing mixture density of solids and the motor is eventually overloaded. (Specialtechnical instructions on this matter are available. It will be furnished upon request).In such case, read the ammeter to monitor the electric current of the motor and adjustthe pump location.MAINTENANCE AND INSPECTIONTo service or repair your pump, please contact your local BJM Pumps distributor.Service should only be performed by a qualified electrician.Insulation resistance of 1MΩ or greater, or unstable values with sudden drops indicatespotential malfunction and should be investigated.Never touch terminals when measuring insulation resistance. Failure to observe thiscaution may cause electric shock.• Pump should be disconnected from the electric power supply before proceedingto do any service or maintenance.12
• Pump should be inspected at regular intervals.• More frequent inspections are required if the pump is used in a harshenvironment.• Preventative maintenance should be performed to reduce the chance ofpremature failure.• Worn impellers and lip seals should be replaced.• Cut or cracked power cords must be replaced. (Never operate a pump with acut, cracked or damaged power cord.)• Seal oil should be checked once per year.• Maintenance should always be done when taking a pump out of service beforestorage.DISPOSAL OF PUMPWhen disposing a pump, treat it as a general industrial waste, abiding by federal, stateand local regulations.TROUBLE SHOOTINGDisconnect the power source to the pump BEFORE attemptingany type of trouble shooting, service or repair.Warning: Pump will restart automatically when motor over-heat protection switchcools.Repair and assembly should be performed by qualified personnel only. Failure toobserve this caution may cause electric shock, injury or fire.1) Pump fails to run (no running noise)No electric current in powerdistribution lineNo electric current in pumpcablePower switch in OFF.
