Introduced in 2012 this unique filter pump offers incredible value for money and a very special feature. The pump comes with two strainer cages, with the outer cage allowing solids (5mm particles) to pass through the pump to the filter. This is the first \'proper\' filter pump to come up with a solution to solid matter blocking the fountain heads. The second strainer blocks solids being circulated allowing a fountain to be run. There are other hybrid pumps on the market but there is nothing that we have seen which is as good as this one. Other pumps have synchronous impellers designed for very light fountain use.
