Recent shipment of salvage pumps: I have tested all the used pumps that I recently acquired.
Primer; the pumps that I use are dry cup piston style, The piston cup is a synthetic material and wears through many years of use. A brand new or remanufactured pump will pull 27” i.e: 90% of atmospheric pressure, @ sea level. A pump that has seen service for 24 hours a day for five+ years will pull 12-14” vacuum, any pump that tests less than 22" vacuum gets rebuilt.
So why do I find like new units in salvage? The only solution I can equate is a distributor gets a new batch of pumps and clears the shelves. FYI; the bottom end of these pumps are basically industrial bullet proof. Oversize sealed bearings, isolated windings, thermal protection, etc., I never have problem with the guts of the pump.
I have a few pumps that pull 25-26” vacuum (compare to a 70,000 mile tire that has less than 5,000 miles, good for many, many years of use). I will sell them for $79 + $16 shipping. They also include a line cord with switch, capacitor, rubber mounts, muffler canister and 1/4" mesh to be formed as a fan guard. The pump will carry my satisfaction warrantee.
2 polyethylene rods, fitted to motor grade sealed bearings, & detailed instructions. This will enable you to make additional sized cups. Limited time offer; 3" PVC cup included no charge if ordered with above kits. $20.00
Note: Pumps are from former operating systems and may exhibit scuffing, minor dents, dirt, dust, and discoloration of aluminum surfaces. this does not impede functionality or operations of the pump.
