Leybold SOGEVAC SV630 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 15 / 18.5 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.

Comparable DVP Alternative
Consider the DVP LX650
Where an exact Leybold replacement is not essential, Vacuum Pumps UK can assess the DVP LX650 as a replacement option for the Leybold SOGEVAC SV630 B.
The DVP LX650 provides 650 / 780 m³/h, compared with 640 / 755 m³/h for the Leybold pump.
The Leybold pump has the deeper stated ultimate vacuum. The DVP model is rated to 0.5 mbar absolute, compared with 0.08 mbar absolute, so the required operating pressure must be checked before changing pump model.
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.
