Rotary Vane Vacuum Pump (Vacuum Pump/Pressure Pump) R-8SN Wiggens Germany
Oil-sealed Rotary Vane vacuum pumps are widely
used traditional vacuum pumps in research and production, which can be used
independently, or serve as backing pumps for molecular pumps or diffusion
pumps. Wiggens' direct driven rotary vane pumps are available as one and
two-stage versions, covering the range from desktop lab pumps to production
line pumps, with low noise and stable working temperature for common voltages
and frequencies, long lifespan, and outstanding reliability for chemical
applications. Various application areas may include vacuum distillation, vacuum
filtration, vacuum inspection, vacuum freeze drying, vacuum coating, vacuum
leak detection, vacuum packaging, vacuum adsorption, etc.
