Gulper Grouper Mk3 Fishbox/Waste Pump w/90° Ports - 24V

Non clog electric Waste pumps without filters, built on more than a decade of market leading valve technology.

Proven Diaphragm Technology
Whale Gulper waste products have been at the forefront of marketing leading waste technology for over 2 decades. Rather than impeller motors, Gulper pumps contain reciprocating heavy duty diaphragms and specialized non-choke valves to handle grey, bilge, black and fishbox waste on board.

Ideal Macerator Replacement in Fishbox Installations
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 replacementfor 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.

A MUST Buy for your TEEN.
Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful! There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says. These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.
