22. PREVENTIVE MaINTENaNcE INSPEcTIONS

To ensure regular pump operation and long life, the purchaser must ensure that regular inspections and periodic maintenance operations are carried
out, with replacement of any worn parts. It is advisable to carry out the below listed preventive inspections at least once a month, or after every 200-
300 hours service:
- check that the power supply voltage is within the established values;
GB
- check that the noise and vibration levels are unchanged, in relation to optimum first start-up conditions;
- using an amperometric clamp, check that the power drawn on the three phases are balanced and that they do not exceed the data plate values;
- check the motor insulation: detach the power cable from the panel and connect the joined cable terminals and the ground cable to the terminals of a
500 V.d.c. ohmmeter. The insulation resistance (motor-cable) must not be less than 5MΩ. Failing this, pull out the unit and overhaul (a cable will need
replacing or the motor must be repaired). Further inspections for electric pumps equipped with the following devices:
- check the oil conductivity which must be >30KΩ, if the electric panel is without the relative warning light;
- check the specific warning light to see whether the thermal probes of the motor have activated.
Ask Caprari SpA for their "Periodic inspections and preventive maintenance" publication, series "K" , for more detailed and scheduled maintenance work.

23. OIL aNd GREaSE INSPEcTION aNd chaNGE

In normal conditions of work, the oil must be changed every 7500 hours and every 2500 hours in heavy duty situations. Used the oils listed below or
similar ones .
Use the relative outlets with 1/2" Gas plugs for the emptying and filling operations.
The opening marked "OIL OUT" is used to empty the oil. Set the machine in a horizontal position or use an oil suction device to completely drain off the oil.
If the old oil is like an emulsion, pour in new oil and check the seal on the pump side.
If there is water in the drained oil, change the mechanical seal on the pump side. The mechanical seal on the motor side should only be replaced if
damaged or if there is fluid in the motor compartment.
The opening with the "OIL IN" indication is used for filling. To access this hole in pumps provided with a stage casing, this latter must first be removed.
When the electric pump is in a vertical position, the correct oil level is obtained when this reaches the base of the fill hole. Comply with the below listed
quantities when the electric pump is set in a horizontal position:
To correctly fill, it is very important to comply with the indicated oil quantity.
The oil reservoir has been designed to ensure an adequate air cushion.
Once the emptying/filling operations have completed, check that all plugs have been well tightened and are complete with their respective new copper
seals. If the oil has been changed, do not throw the old oil away.
Give it to those companies authorized for oil disposal (apply to the relative COBAT Authorized Consortia in Italy).
Bearings must be lubricated with lithium grease type ESSO - UNIREX - N3 or equivalent filled at 70% only in case of bearing replacement or electric
pump repair.
In case the lower mechanical seal undergoes a failure, an oil emission in the pumping fluid may happen.The safety card concerning
the oils used by Caprari can be required directly to Caprari S.p.A.The oil filling provided of F.D.A. certification can be even asked
to Caprari S.p.A.
