Product Overview
The SOGEVAC SV25 B is a direct-drive rotary vane vacuum pump engineered for continuous industrial duty in the low to medium vacuum range. Manufactured to the SOGEVAC single-stage rotary vane platform, the SV25 B operates on a proven eccentric rotor and sliding vane working principle: centrifugal force and oil film pressure hold the vanes against the stator ring as the rotor turns, creating expanding and contracting sealed chambers that draw gas from the inlet and discharge it through an integrated exhaust valve. The pump is driven by a flange-mounted motor through a rigid coupling, eliminating belt wear and ensuring stable pumping speed across the operating range. With a nominal displacement of approximately 25 m³/h, the SV25 B serves as a compact, reliable vacuum source for backing turbomolecular pumps, roughing vacuum chambers, and general industrial vacuum services where oil-sealed rotary vane technology is preferred for its low noise, low vibration, and tolerance of condensable vapors when fitted with a gas ballast facility.
