Leybold SOGEVAC SV120 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 2.4 / 3.2 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.

Typical Leybold SOGEVAC SV120 B Applications
› vacuum packaging and chamber machines
› thermoforming equipment
› vacuum handling and lifting
› printing and paper machinery
› general OEM machinery
› small central vacuum systems
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 LC151
Oil lubricated rotary vane vacuum pump
Comparable DVP Alternative
Consider the DVP LC151
Where an exact Leybold replacement is not essential, Vacuum Pumps UK can assess the DVP LC151 as a replacement option for the Leybold SOGEVAC SV120 B.
The DVP LC151 provides 151 / 181 m³/h, compared with 120 / 147 m³/h for the Leybold pump.
The DVP model also has a deeper stated ultimate vacuum of 0.1 mbar absolute, compared with 0.5 mbar absolute for the Leybold pump.
Because the LC151 provides more volume, the DVP LC106 could also be considered where the nominal capacity is not as crucial for the application. It provides 106 / 127 m³/h and a stated ultimate pressure of 0.1 mbar absolute with a reduction in energy used..
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.
