surge vacuum pump

[flooder]

has anyone ever used a surge alamo 40 plus vacuum pump?any ideas on keeping it cool?

I have 4 alamos, all with oil reclaimers. the more oil coming into the pump the cooler it will stay. a good vacuum regulator helps also. I run mine up to 25" of vacuum for 5 days straight, no problem.

is there any such thing as having too much oil going into the pump?

Yes A vacuum pump is also a compressor so you dont want so much oil that you try comressing it or blowing the seals out. There is a happy mediam so over doing the oil will displace the voluum of air entering the pump. Less air in less CFMs the pump will pull.

If the oil is for cooling you dont need to flood the system you only need enough oil to obsord the heat and carry it away......BUT CHUCK you use the word flood all the time! Thats true But its a discription of the type of system. You are adding alot more oil to the pump to both lube it and cool it. These pumps dont need alot of oil to lube them. But when it comes to cooling you only need enough oil to gat as hot as possible in the VERY short time its in contact with the pump and hot air/gas that enters the pump and then exits.

Another thing to remember is older pumps turned at lower RPMs and now that we are speeding them up a bit its helps to have more oil in them to fill the vanes and keep a nice layer of oil to keep ware down and Vacuum up.
