CL drum filter
Preliminary information: Please bear in mind that the gravity version and the pump version of the drum filter are based on different performance data. With the gravity version, the drum is almost always submerged up to the flushing channel. This means that the fabric is almost completely utilised there. With the pump version, the water level is always lower in the drum and then builds up according to the degree of contamination until the control initiates flushing. This means that with the pump version you have much less fabric surface available and therefore the flow rate is also reduced. Rule of thumb is approx. 35% less flow rate with a pump version, e.g. PP35 - flow rate with gravity 35m³ / hour and with pumped version 22.75m³ / hour
