Evolution Aqua Cetus Sieve Gravity Fed Pond Pre-Filter

The gravity fed model is installed so that the maximum water level in the Cetus Sieve is the same height as the maximum water level in the pond. The Cetus has a variable inlet height using the unique Pondflow regulation system which is utilized in gravity systems.This allows for variations in the ponds water level without starving the circulating pump for water. Water is then passed through a 300 micron screen which removes a vast amount of solid wastes.Water must then be pumped from the Cetus Sieve to a filter that is situated above pond level which can be pressurized or gravity fed back into the pond.
