7 Servicing/Maintenance
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.
Such indications could be:
▪ Temperature rise in the fluid handled
▪ Increased sand content of the fluid handled
▪ Change in power consumption
▪ Change in discharge head/flow rate
▪ Change in frequency of starts
▪ Increase in noise and vibration levels
Regular inspection does not require the submersible borehole pump to be removed
from the well/tank.
For any queries and repeat orders, particularly when ordering spare parts, specify the
following information (see name plate(⇨ Section 4.3 Page 17)):
▪ Pump and/or motor type series and size
▪ Operating data
▪ Order number
For information concerning repair jobs and spare parts please contact your nearest
KSB service centre.
