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.
▲ ATTENTION!!!!!
It's necessary to effectuate all the operations with gloves and glasses suitable for the product used then
consult the supplier of the chemical product.
