7.1 Servicing/inspection
The submersible borehole pumps are generally maintenance-free. In order to pin-
point 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 discharge head / flow rate
▪ Change in switching frequency
▪ 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 (see 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.
