Ultra-Sieve 3 (Max Flow 4000GPH)

  How it works: Pond water will flow over the top of theauto-adjustable dam (A). This dam is connected tothe floater so its height is automatically adjusted.This system will provide that the exact amount ofwater that is pumped out the filter will enter the filteron the inlet. This has a number of big advantages incomparison with other sieve filters:Multiple, or bigger, inlets are possible (standard 2 x110mm!). The upper edge of the UltraSieve must onlybe 1 cm above the water level.Very competitivepricing thanks to the simple floating system.Pump speed up to 20m3/hr.
