MAINTENANCE
3.1.
When the pump is new or reassembled
If the pump is new or reassembled after maintenance it is important to retighten the
pump housing nuts (pos. 37) after a few days of operation.
Make sure to use the right torque – see chapter 5.5 “Tightening torques”.
3.1.1.
Performance test
When installation is new, a test run of the pump should be conducted. Gauge the capacity
at specific air pressure/flow. This information is useful for checking performance in the
future as wear takes place. You will be able to set schedules for maintenance of the pump
and to select spare parts to be kept on stock.
3.2.
Routine inspection
Frequent observation of the pump operation is recommended to detect problems. A change
in sound of the running pump can be an indication of wearing parts (see chapter 3.4
"Location of faults" below).
Leaking liquid from the pump and changes of performance may also be detected. Routine
inspections should be conducted frequently.
3.3.
Complete inspection
The intervals for a complete inspection depend upon the operation conditions of the pump.
The characteristics of the liquid, temperature, materials used in the pump and running time
decide how often a complete inspection is necessary.
If a problem has occurred, or if the pump is in need of a complete inspection, refer to
chapters 3.4 "Location of faults" and 3.5, 3.7 "Dismantling of the pump". You are of course
warmly welcome to consult us for further help.
Parts that are subject to wear should be kept in stock, see our recommendations in chapter
4.7 “Stocking recommendation”.
