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.
➢
Gear oil must be exchanged in accordance with the gear 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 5.5 “ 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.
3.4. 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.
Nevertheless, Tapflo recommends to inspect the pump at least once a year.
