SED-ZKB1-J (DRV series) two-stage oil-sealed rotary-vane vacuum pump family, 5 sizes (24–90 m³/h @ 50 Hz), with springless vanes, forced lubrication, and hydraulic oil anti-suck-back system. Ultimate pressure ≤0.5 Pa (ga
Como funciona
A four-pole motor drives the rotor through a flexible coupling. Rotor vanes (springless) are pressed against the cylinder wall by centrifugal force and an air-spring effect, dividing the cavity into intake and exhaust zones whose volumes change periodically. Gas entering through the KF inlet is compressed and discharged through the exhaust valve via oil pressure. A gas-ballast valve introduces air into the exhaust cavity to reduce vapor partial pressure and prevent condensation in the oil, extending oil service life.
