The Logos through the history of Pumping Station: One
The exact font is unknown and you can blame James T. Burke for that.
It appears that it is a hybrid font made by mixing a bunch of fonts and rounding over select corners - Jim you monster.
Characters of note
M - Delvon Family Alt - most notable element, just a weird shaped stroke stem combo and I've only found it here
S,G,A - Netraly - of note the terminals are far from the median and the s has an almost horizontal spine, the A has a tall crossbar
P,U,T,I,O,N,E - Framer Sans 700 - these letters are pretty standard in many fonts, but I believe this one font covers them all the closest
P - Edmund Regular - the closed counter is squared off here and can also be an influence of small rounded corners
