Floating extraction with suction filtration ensures that the pump always draws the cleanest water from the storage. If however, coarse particles entered the tank, then the floating extraction retains them and protects the pump. The suction filter should not be too fine-meshed to prevent blocking by biofouling. This blocking can rapidly develop to defects in the pump. The ideal mesh size of the suction filter is around 1 mm.
