The Rotorflush Filterpump is a submersible pump with an integral self-cleaning intake filter. This unique self-cleaning intake filter enables the pump to operate in water contaminated with a high degree of suspended solids without blocking or affecting the performance of the pump.
How it works:
A rotating impeller with two angled jets sits inside the intake filter screen, the blue arrows show the main flow of water being sucked into the pump through the screen. The red arrows show filtered water inside the filter being diverted into the impeller and ejected out through the rotating jets.
