Description
UltraSieve filters are the most reliable prefilters on the market. This is due in part to the simple design with just one moving part. The prefilter is not self-cleaning, but is very easy to maintain. Open the knife gate valve and the dirt is discharged. UltraSieve prefilters feature a stainless-steel filter element that never needs to be replaced. Thanks to the triangular stainless-steel rods angled at 7°, water passes directly through the sieve while dirt is trapped. A major advantage of this principle is that dirt is genuinely removed from the water flow. This has a major effect on water quality because waste is no longer released into it.
Operation
Pond water flows over the removable wall, which is connected to a float so that its height is adjusted automatically. This level adjustment therefore ensures that exactly the amount of water pumped also flows back into the unit. In a sieve filter, pond water is directed onto a curved sieve downstream of the removable wall. The sieve consists of hundreds of triangular rods spaced 0.2 or 0.3 mm apart (i.e. 200 or 300 microns). The rods are slightly angled so that coarse waste is trapped while the "sieved" water continues on its way. The sieved water is then directed to the main filter.
Why UltraSieve prefilters?
