The Gulper Grouper Mk 3 builds on the decades of proven pump technology and now features 90┬░ inlet and outlet ports with integrated non-choke valves. The improved design allows the pump to be used as a direct replacement for macerator impeller pumps.

Compared to typical macerators, the Gulper Grouper Mk 3 is quieter and lightweight. With diaphragm technology, the pump does not clog or suffer from motor burn out meaning a longer system life and less unwanted maintenance jobs! With a low power consumption and run dry capability the Gulper Grouper Mk 3 really is the pump of choice for fishbox evacuation.
