Vacuum Pumps
| Blowers | Blower Vacuum Pumps: These are positive displacement pumps that operate by pulling air through a pair of meshing lobes not unlike a set of stretched gears. Air is trapped in pockets surrounding the lo.... |  |
| Dry Mechanical | Dry Mechanical Vacuum Pump: Dry screw vacuum pumps operate without oil or water in the pumping chamber, and with their straight-through design, they can handle both condensable vapors and some solids .... |  |
| Jet | Jet Vacuum Pump: Also known as an ejector pump, works by converting pressure energy of a moving fluid into velocity energy as it flows through a relatively small nozzle. The lowered pressure of the mo.... |  |
| Liquid Ring | Liquid Ring Vacuum Pump: A rotating positive displacement pump. Its function is similar to a rotary vane pump except that the vanes are part of the rotor and churn a rotating ring of liquid to form th.... |  |
| Once thru oil | Once-Through Oil Vacuum Pumps. These pumps, also called OTO pumps, are the sliding-vane type that uses once-through oil to seal clearances and lubricate moving parts. Vanes are in slots in a rotor, mo.... |  |
