Ultra Sieve 3 Pond Sieve

New and improved sieve.

Based on the very successful UltraSieve II but now with a fully patented automatic adjustment!

How it works:

Pond water will flow over the top of the auto-adjustable dam (A). This dam is connected to the floater so its height is automatically adjusted. This system will provide that the exact amount of water that is pumped out the filter will enter the filter on the inlet.

This has a number of big advantages in comparison with other sieve filters:

Multiple, or bigger, inlets are possible (standard 2 x 110mm!).

The upper edge of the UltraSieve must only be 1 cm above the water level.

Very competitive pricing thanks to the simple floating system.

Size: 78.5cm x 37cm x 100cm


Max Pump speed: up to 4400gph

Would be advisable to use a rubber boot on the input as this unit is made from Polypropylene and is not ideal for glueing to.
