Vacuum pumps
These are 2 styles of vacuum pumps that I have.
The one to the left is a piston style and the right one is a dual diaphragm pump that has 2 functions:
  You can use it as a vacuum or by changing the hose position over to the exhaust ports; it can be a pressure pump.
Both pumps are rated at about 28mm Hg and are attached to a 1/16 hp 120V AC  motor @ 1700 rpm.
They also come with a start capacitor and directions on how to hook it up.
The motors are twin shaft ball bearing and built to last.
They can be used for a heavy duty fish tank air pump or to vacuum set laminations on wood or to pump gases from one tank to another (diaphragm pump only).

Price is $45.00
