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.
