Swell Foam Pre-Filters

Cost effective and efficient, Swell Foam Pre-Filters will fit most of the popular brands of submersible pumps, keeping them operating for longer intervals between maintenance and increasing your pump's overall lifespan

These 8 inch square cubes have a large surface area making them ideal for straining water entering a pump and therefore protecting your pump from larger particles, stones and sludge.

The pump fits into either an off-centre hole or central hole, allowing pump and foam to sit level with the pond bottom - where it needs to be. Both cubes have inserts to fit most pumps, making these pre-filters extremely adaptable.
