Gulper Grouper Mk3 Fishbox/Waste Pump w/90° Ports - 12V

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.

Good for medium and large dogs not good for small dogs
Too big for dogs under 15 pounds. Treats are hard to get out of the four corners. My dog can barely pick this up. She weighs 12 pounds. She still found it interesting though trying to dig the treats out that she was unsuccessful. Even after I cut all the little triangle prongs off the four corners the treats are still stuck in there. There is a slot on the side that I can put half of a dental refill in the side and she can eventually get it out so there’s still somewhat of play and challenge received, but not that satisfied to me.

Great for aggressive chewers!
Size: Jumbo, Style: Peanut Butter
I have a very very aggressive chewer. She is a Rottweiler/Pitbull mix. Most toys she completely destroys within 2 days, sometimes 2 hours. I must praise this toy as she has had it for over 5 months and has not destroyed it! She loves chewing the ends and carries in her mouth squeaking it as she goes. I have 4 pups and they all take turns chewing when they can. I will be buying more Playology dog toys in the future. Thank you for making such a great toy!!

They are her favorites
Size: Medium (VALUE 2-Pack), Style: Beef, Size: Medium (VALUE 2-Pack), Style: Beef
We’ve had many dogs, many very destructive ones and wish I had these years ago. The hard toys get sharp edges, this toy is the best and yes is far better than the other red ones. My bulldog wants tug of war for 30 min to an hour every night. We’ve gotten tennis elbow, tendinitis, and pulled muscles holding onto this thing. She has tons of toys but 9pm and this is only option for her. We don’t get a choice. Easy to hold, well for a few min until your hand gets tired. First you one was about 3 years ago and she’s only on her third one. They last forever, easy to clean, and aren’t sharp edges. Seriously, better than any toy sold anywhere. My phone has hundred of pictures of Pickle holding this. She’s doing it right now. If you have a strong destructive dog that takes pride in destroying toys, ruin their confidence and get them this one.

Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!
