SuperSieve XL

SuperSieve Medium and Large both have a 3 x 110 mm inlet thus providing the option of connecting 2 bottom drains combined with a skimmer, for example. Model XL even has a 4 x 110 mm inlet. In addition, the SuperSieve offers the possibility to easily mount 1 (model M and L) or 3 UV lamps (model XL) at the bottom.
The swing-flap completely opens and closes when there is a fairly small change in the water level below the screen. As a result the SuperSieve maintains a very stable and high water level below the screen. This is important for preventing air bubbles in the pump. The screen is carefully sealed to the housing itself with specially manufactured rubbers, so that it is impossible for water (and therefore dirt) to pass by the screen without being filtered.

The water is channelled onto the screen via baffles. A guide baffle has also bee installed below the screen designed to calmly channel the water as far as possible away from the 90 mm pump connectors.
The SuperSieve has multiple 90 mm pump connectors, making it possible to connect an additional skimmer pump as well. A 700 microns sieve element and a lid are available as an option for each model.

Internal overflow
The sieve’s internal overflow is the distance from the top of the housing to the point where the water internally overflows onto the screen. The larger this distance, the greater and more flexible its deployment. Because the water flows to the SuperSieve via communicating vessels, the maximum available water pressure available for this purpose is determined by this height. For the XL the height differential is 22 cm, this corresponds to a water pressure of 0.022 bar. This water pressure is required to displace the water from the pond to the sieve. Prior to installation, the SuperSieve must be located 3 cm above the maximum water level and the installation must take the fluctuating water level of the pond into account. Suppose the pond’s water level drops by 5 cm (for example, when the filter is rinsed). In that case only 0.022 of the 0.014 bar remains. If a sieve only has a 17 cm height differential, this means that in this scenario only 9 cm or 0.009 bar remains to get the water through a pipe from the pond to the sieve. This often gives rise to critical situations because too little water then reaches the screen. The pump then often takes in air, which causes noise disturbances and cavitation (accelerated wear) of the pump.
