Leybold Sogevac Pumps: Models SV16 - SV65,

& UV 25

Model SV 16 Model UV 25
Compact and extremely easy to operate, Leybold's Sogevac rotary vane pumps are designed for continuous operation over the working pressure range from atmosphere to less than 1 Torr (29.9 in. Hg). These single-stage oil-sealed vacuum pumps have a gas ballast valve to prevent condensable vapors from mixing with the pump oil, an anti-suckback valve actuated whenever the motor stops or slows to keep backstreaming oil from diffusing into the chamber, and an internally mounted fan which eliminates the need for water or coolant piping. All models except SV 16, SV 25, and UV25 also feature an external spin-on filter designed to remove particulates from the oil. Applications for Sogevac SV include:
  • the production of vacuum for circuit board hold-down in A.T.E applications

  • vacuum processing and packaging in the food preparation industry.

  • vacuum degassing

  • thermal forming of plastics

  • vacuum drying and impregnation

  • leak testing

  • vacuum stirring and mixing.
