The professional surface suction system for any garden, koi, and swimming pond combines with biological water treatment. It effectively draws only surface water through a precisely functioning skimmer weir, removing dirt and dust from the pond. An important component is the gap screen attached to the large inner basket, which has a self-cleaning effect. The accumulated dirt can be easily disposed of by lifting and emptying the inner basket. Ideal installation at the pond's edge by embedding it in the ground. Installation directly into masonry (wall thickness up to 260 mm) is also possible. Recommended pump capacity is 4,500 - 20,000 l/h. Connections DN 150 (gravity) or 44.9 mm/1½" IG (pump version). Material: stainless steel.
