3.0 MAINTENANCE
3.1 General maintenance comments
Regular maintenance is essential if the pump has to give good service over a long period.
The following advice should be strictly followed:
It is difficult to estimate the periods between maintenance operations, because of the pumps operating
conditions and the chemicals employed. It is therefore the basic responsibility of the operator to check
regularly the appearance and condition of the pump and to clean and service it according to his findings
3.2 Periodic maintenance
Liquid's level in the tank should be monitored regularly and the tank refilled a
necessary to avoid the running dry of the pump. Wet parts of the pump, foot valve,
suction/delivery valves and the head and diaphragm should be inspected and cleaned
at least every 3 months. Where very aggressive chemicals are being dosed, (Sodium
Hypo chlorite is particularly difficult) this period may need to be reduced and cleaning
be carried out more frequently. If pumps are not used for long periods, scale, sediment
and encrustation deposits can build up causing the pump to malfunction. We highly
recommend careful maintenance of the valves by running them under clean water
after long periods of non use. Alternatively, if the pump has not been used for long
periods, before re-setting up the operations, we strongly recommend operating it for at
least 30 minutes with the foot filter immersed in clean water to flush the pump.
3.3 Basic maintenance procedures
Before doing any maintenance read with attention the technical and safety characteristic of the dosing
chemicals and follow the next procedures:
1 Turn off the pump and immerse the foot filter and the injection tube in clean water. Turn on the pump to
let the water go through the pump head. If there are some crystals to be cleaned follow the next
procedures:
2 Immerse the foot filter and the injection tube into an adequate solution to remove the crystals (ex.
Chloridric Acid for Sodium Hipochlorite crystals); let the pump work for some minute. Then repeat the
action with water and connect the pump to the plant.
