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

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.
