RC keep that pump -a real bargin and runs cheap IMO. It should last 20-30 yrs if you 'rebuild' the vanes a few times. It operates at close to 4-5 hrs per kilowatt of electricity. Check your power company rates for each KW of electricity and it will give you a good idea of power cost.
Hey Bill thanks for the info. I thought the price was decent! I am picking up the pump from a buddy of mine in the next day or 2. I will go through it all for sure as this is my first Gast I would like to kind of use it as a ginnie pig. Do you have any links to some good videos for rebuilding and maintaining them?
Thanks,
RC
