Operating instructions
WTS 102/3-en 13
Regular monitoring and maintenance will extend the life of your pump or pump
system.
• You must observe the area of application given in the Confirmation of Order.
• Do not exceed the output given on the motor rating plate.
• Running dry, running against a closed pressure side valve or operating in the steam phase of the
pumping medium are to be avoided at all costs.
• Avoid sudden changes in temperature (temperature shocks).
• The pump and the drive machine should run evenly and with no vibrations, check at least once a
week.
• Check functioning of the lubricant supply.
• When operating on automatic control:
Check that switching functions are working properly.
if using pure water or grease lubrication leave the lubricant supply switched on during standstill
times unless the supply is automatically switched on or off with the pump (see Point 4.5
„Starting up“).
• Pumps which are exposed to corrosive chemicals or to wear through abrasion must be inspected
periodically for corrosion or wear and tear. The first inspection should be carried out after six
months. All further inspection intervals should be determined on the basis of the state of the
pump.
Permissible Number of Operations
At a motor output up to and including 7,5 kW a maximum of 40, at higher output a maximum of
20 starts per hour are permitted.
4.7 Shutting down
• Close slide valve in discharge pipe. This is not necessary if there is a spring-loaded non-return
valve.
• Switch of motor (make sure it runs down quietly).
• Switch off the pure water or grease lubricant unless a continuous supply of lubricant is necessary
due to the nature of the pumping medium (e.g. sticky) or the pump is being operated on
automatic control.
• If there is any danger of freezing, empty pump and pipes completely.
4.8 Dismantling
The operator's or manufacturer's fitters should be informed as to the nature of the
liquid handled. In the case of pumps handling dangerous liquids, the liquid
handled should be disposed of by environmentally acceptable means before the
pump is dismantled.
• Before starting to disassemble the pump unit make sure that it cannot be switched on again.
• Pressure line shut-off must be closed.
• All components must have cooled down to ambient temperature.
• Before dismantling the pressure line make sure that it is empty and depressurised.
• When the pump has been dismantled: Secure the opening of the shaft.
