The hard working folks in Uganda have come up with a new plan for the Gulper 2.0, formally known as the Rammer, which includes a better design of handle. In addition they have also created technical drawings for the Gulper 1.0. Feel free to copy, amend, adopt and innovate.

Hi,

I saw some earlier post inquiring about technical drawings of the Gulper, i have tried to upload them to the post so i hope they will work. I have also added the technical drawings of the Rammer which we have tested in Uganda and has proven to be much better in the field than the Gulper

Hi All,

George here - An engineer based in Uganda responsible for overseeing the development of the Gulper II (Rammer)

Its advantages over the Gulper 1:

- The donkey tail makes emptying quicker and cleaner
- The hose outlet makes the operation cleaner as the sludge can be deposited directly into the bottom of a barrel
- The rammer is extendable and can therefore go deeper into the pit - tested up to 2.5m
- The outer cylinder and valve moves up and down rather than an internal plunger (Gulper I). This rising cylinder 'pushes' into the sludge, meaning there is less reliance on overcoming the shear strength (or thickness) of the sludge. This is what allows it to pump thicker shit.

We are currently testing different valve designs and cage spacing sizes on a synthetic sludge that contains solid waste - condoms, tampons, sanitary pads, hair, etc. This will give us a better understanding how the design can prevent the device from becoming blocked.

Technical drawings of the Gulper II can be found here: sanihub.blogspot.com/

We have built up a stock here in Uganda, and we can ship them across Africa if anyone would like a prototype

Thanks,
George
