7 Servicing/inspection

7.1 Servicing/inspection

The submersible borehole pumps are generally maintenance-free. In order to detect
indications of potential damage at an early stage, regular checks are required.
Possible indications of potential damage:

▪

Temperature rise in the fluid handled

▪

Increased sand content of the fluid handled

▪

Change in current consumption

▪

Change in head / flow rate

▪

Change in frequency of starts

▪

Increase in noise and vibration levels

The submersible borehole pump need not be removed from the well/tank regularly
for inspection.

For any queries and repeat orders, particularly when ordering spare parts, specify the
following information given on the name plate:

▪

Pump and/or motor type series and size

▪

Operating data

▪

Order number and/or material number

For information concerning repair jobs and spare parts please contact your nearest
KSB service centre.
