Operating instructions
4.6 Operation and Monitoring
Be particularly careful not to touch hot machine parts and when working in the
unprotected shaft seal area. Remember that automatically controlled systems may
switch themselves on suddenly at any time.
Suitable warning signs should be affixed.
Regular monitoring and maintenance will extend the life of your pump or pump
system.
•
You must observe the area of application given on the Data Sheet.
•
Do not exceed the output given on the motor rating plate.
•
Avoid dry running, running against closed discharge valves or operation whilst the liquid
handled is in the vapour phase.
•
Avoid sudden changes in temperature (temperature shocks).
•
The pump and motor should run evenly and without vibrations; check at least once a week.
•
The bearing temperature (measured on the bearing frame) should be max. 50 °C above ambient
temperature and should not exceed 90 °C; check at least once a week.
•
Check oil level at least once a week and top up if necessary.
•
Check leakage rate from packings at least once a week (see Point 4.5 „Packings“).
•
Check the regulating and monitoring facilities of any sealing, flushing or cooling systems once a
week to ensure that they function properly. Outgoing cool water should be body temperature.
•
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.
Permitted number of starts
Do not exceed the pump's permitted number of starts - see diagram.
With electric motors, the permitted number of starts is given in the attached motor operating
instructions.
If two different figures are given, the lower figure is valid.
