Here it is the Ultrasieve Midi, a smaller version of the successful Ultrasieve III

The UltraSieve Midi is a Gravity Fed pre-filter to filter waste solids from the water via a bottom drain or through a skimmer. This technique is based upon the very successful Ultrasieve III, which incorporates a sieve-bend. A sieve-bend consists of hundreds of sharp stainless steel profile wires with very small slot openings where the water can go through but the solids stay on the sieve bend. In practice it works as follows: The water enters the Ultrasieve Midi via the Ultraskim or bottom drain and passes through the “auto-adjustable” dam and will go upwards and fall over the weir on to the Stainless Steel sieve-bend.

The water goes through the sieve bend and the waste solids will slowly go down to the waste area. At the waste outlet of the filter is a 2 inch male thread connection with end cap for attching a 2 inch slide/Ball valve to easily wash away the waste with water. When the water in the tank underneath the sieve-bend is not pumped away fast enough the water will raise which makes the floating system (auto-adjustable dam) go up to reduce the incoming water flow.

UltraSieve Midi Technical Specifications:

• The maximum flow of the UltraSieve Midi is 12000 lph.
• 74 cm deep x 27 cm wide x 56 cm long
• Inlet 110 mm spigot Polypropylene
• Outlet 2 inch
• Sieve Bend Stainless Steel 316
• Capacity Max. 12000 l/hour
• Comes with a 300 micron Stainless Steel screen.

The perfect solution for pump capacities up to ±12m³/h. (12000 lph) The most ideal pre-filter! Create a compact filter system by combining the UltraSieve MIDI with a beadfilter or other pump fed filters.

The pump connection comes with a long suction pipe which draws the water from under the float to prevent air suction.
