    I have a lot of oil lubricated vane pumps running, and they are about all trouble free. Just replace the oil yearly. Mostly available in the higher capacity range. (15-100 m3/h)

    The roc-r pumps generate just a little less vacuum, but are also cheap to run (maintenance) but in general are a lot smaller. (2-10 m3/h).

    Oil free pumps are nice to have in the car. If they fall over, they do not leak oil...

    most people use rotary vane pumps for infusion work over here...

    You can get a really great one on ebay if you look for the items sold by bluelooneym I bought a 5 cfm pump for $79 plus shipping and it works great, also it's a continuous operation pump.

    Great price on a good pump.
