AquaForte Ultra sieve III Mechanical Filter (7900 GPH Max Flow)

$2,649.98 $1,900.00

This filter catches very small particles that accumulate in your pond, and on top of that it gets them completely out of the water column! It also has two inlets for piping from skimmers and/or bottom drains.

Shipping costs will be additional and billed separately from this order due to the fact that these usually ship by freight. Therefore there is no standard or typical charge, and each order will be individually calculated based on distance.

SKU: UltraSieveIII Category:


The most compact, gravity fed, sieve filter with the highest pump capacity. For years this has been the leading and most reliable pre-filter for professional koi ponds. Now supplied with an extra large waste outlet,
including a slide valve 90/110

How it works:
Pond water will flow over the top of the self-adjusting weir. This weir is connected to the float so its height is automatically adjusted. This system will ensure that the exact amount of water that is pumped out the filter will enter the filter on the inlet. Underneath the screen the unit has stabilizers to prevent expansion when the unit, accidentally, totally fills with water. The UltraSieve III comes with a pump connection of a 2" male threaded adaptor. The waste outlet is fitted with a 90/110mm slide valve. The pump connection comes with a long suction pipe which draws the water from under the float to prevent air suction. This filter must be installed so that the top of this unit is about 1" above the water level of the pond.
