Introduced in 2012 this unique filter pump offers incredible value for money and a very special feature. The pump ships with two strainer cages the outer cage allows solids 5mm particles to be passed through the pump to the filter. This is the first 'proper' filter pump to come up with a solution to solid matter blocking the fountainheads. The second strainer blocks solids being circulated allowing a fountain to be run.There are other hybrid pumps on the market but none we have seen are as good as this one. Other pumps have synchronous impellors designed for very light fountain use
