Grimm 2X6 raised flue/preheater/SS hood
300 taps on vac/Gast vac pump/Bernard mechanical releaser.
I have until I fried it due to operator error What type of info are you looking for. Why the change from the Gast if your getting 22HGs?
I have until I fried it due to operator error Im pulling 24 when everything is working good in the woods I do have flood oil so it does run cooler and I dont use a regulator so it at full vac and HGs.What type of info are you looking for. Why the change from the Gast if your getting 22HGs?
A friend of mine was given the 74 and we're looking for information for him, recommended rpm's, vac and cfm numbers. I'll stay with the Gast, its a great pump and oilless.

delaval rpms on these pumps should be around 1500-1600 which means a slightly larger pulley on pump and smaller on motor, cfm will depend on motor size probably around 50-60cfm @ 15 in with 5hp motor with good oil flow, short exhaust and open air flow around unit should be around 20" continous but cfm will drop some
Dang that sounds high on the RPMs My Delaval had 540 RPM recommendation. Dont remember what unit was.
