7.- MAINTENANCE
Periodically check the chemical tank level to avoid the pump
operates without liquid. This would not damage the pump, but
may damage the process plant due to lack of chemical.
DOSITEC series dosing pumps are all supplied with level control
setting. The level switch is not included therefore to be ordered
separately.
Level control stops pump operation once the level into the
chemical is lower then the level switch,activating a L.E.D. on the
pump .
Check the pump operating condition at least every 6 months,
pump head position,screws, bolts and seals; check more
frequently when aggressive chemicals are used.
Is recomended to clean periodically the hydraulic part(valves and
filter). Cleaning frecuency will depend on the aplication.
Before any maintenance operation check:
The pump is stopped and disconnected from the electric supply.
There is no pressure neither inside the head nor in the impulsion
pipe. It is advisable to empty the head before opening it.
The staff in charge of the maintenance will use the adequate
protection means in order to manipulate the dosed liquid.
