With a pneumatically activated control valve
The filter must be installed as close as possible to the pump, should allow easy inspection and have the following
characteristics:
1. Minimum capacity 3 times greater than the pump’s rated flow value.
2. Filter port diameters must not be smaller than the pump inlet ports.
3. Filtration degree ranging between 200 and 360 µm.
In order to guarantee correct pump operation, it is important to plan periodical cleaning of the filter
depending on actual pump usage, water quality and actual clogging conditions.
