DV Series Rotary Vane Dry Vacuum Pumps The DV series of pumps are 100% oil-less rotary vane vacuum pumps. They are designed to operate on a continuous basis at any point from atmospheric pressure to a vacuum level of 22.5—27" Hg depending on the pump model. The oil-less pumps are ideal for applications where oil or water sealed pumps are objectionable. The pumps are direct drive units and are supplied with TEFC electric
motors, inlet filter, vacuum relief valve, vibration isolators and discharge silencers (as required). Applications include graphic arts, vacuum packaging, forming, hold-down, robotics, material handling, air sampling, central vacuum systems and others. |
