3. MAINTENANCE
Maintenance work on electrical installations must be performed by qualified
personnel and only when the power supply has been shut off. Wait five minutes
for capacitor to discharge before opening the pump.
Follow the local and
national safety regulations.
Due to size of some of the pumps at least two persons should perform maintenance
activities and if needed use appropriate lifting devices according to local rules and
regulations.
3.1. Inspections
➢
Periodically check suction and discharge pressures.
➢
Inspect the gear-motor according to the instructions from the motor manufacturer.
➢
Gearb
ox
oil must be exchanged in accordance with the gearb
ox
manufacturer instruction
manual.
3.2. When the pump is new or reassembled
If the pump is new or reassembled after maintenance it is important to retighten the
screwed connections after one week of operation.
Make sure to use the right torque – see chapter 5.4. Tightening torques.
3.2.1. Performance test
When installation is new, a test run of the pump should be conducted. Gauge the capacity
at specific pump speed. 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.
3.3. 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
3.5
"Location of faults" below). Hose damage can be the main reason of liquid leakage therefore
it is advisable to install a hose rupture monitoring system that can detect the hose damage
and stop the pump when liquid enters the pump chamber.
Leaking liquid from the pump and changes of performance may also be detected. Routine
inspections should be conducted frequently. We recommend to conduct a daily check and
keep records of the following:
➢
Leakage of fluid form any connection of the pump
➢
Tightness of all connection parts of the pump and any peripheral equipment
➢
Complete inspection in regular intervals has been done
In case any of the above is not fulfilled, do not start the pump and implement corrective
actions.
Establish a preventive maintenance schedule based on the pump’s service history. Scheduled
maintenance is especially important to prevent spills or leakage due to hose failure.
