A friend of mine had a diff pump I am selling for him. It is a water cooled Daivac DPF-4Z, throat measures 4.5". 100v heater at 700watts. It wants .2 torr fore line pressure and will do x10^-7 ultimate pressure. 570 l/s pumping rate and holds 150cc of oil.
Seems to be something like a ASA flange fitting. I have not measured it to be sure. It comes with a water cooled spiral baffle as well. No o-rings on either the pump or the baffle. The baffle is just clamped between the pump and whatever it is being mounted to.
Seems pretty clean, I cant tell what kind of oil it was used with but it is not burnt.
$150 plus shipping.
There are a few more of those water cooled baffles available if anyone needs one.
