Leybold SOGEVAC SV25 B Overview
The SOGEVAC range is widely used on packaging, process machinery and general industrial vacuum installations. Oil lubricates the working components, contributes to sealing inside the pumping chamber and assists thermal control during operation.
For this model the stated motor rating is 0.9 / 1.1 kW. Exact voltage, motor build, gas ballast arrangement and connection details should be confirmed from the installed pump before replacement.
Vacuum Pumps UK can advise on replacement options, while VacAir Superstore supports Leybold SOGEVAC pumps with oil separators, spare parts, oil, servicing and workshop repairs.

Application suitability depends on the operating pressure, gas load, contamination level, vapour handling and duty cycle. The nameplate and process conditions should be reviewed before changing pump model.
DVP LC25
Oil lubricated rotary vane vacuum pump
Comparable DVP Alternative
Consider the DVP LC25
Where an exact Leybold replacement is not essential, Vacuum Pumps UK can assess the DVP LC25 as a replacement option for the Leybold SOGEVAC SV25 B.
The DVP LC25 provides 25 / 29 m³/h and uses less energy than the Leybold pump.
Both pumps have a stated ultimate pressure of 0.5 mbar absolute.
Final suitability should be checked against the actual working pressure, process conditions, mounting dimensions, inlet position, connection size and motor supply.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
