Becker U 4.630 F/K Overview
The Becker U 4.630 F/K is a high-capacity oil lubricated rotary vane vacuum pump designed for continuous industrial service where strong pumping speed, dependable vacuum performance and production reliability are required.
With a nominal pumping speed of 624 m³/h at 50Hz and 732 m³/h at 60Hz, it is suitable for larger packaging machinery, process equipment, central vacuum installations and other demanding industrial vacuum applications.
Oil within the pump lubricates the working components, assists sealing and helps control operating temperature. Integrated exhaust separation helps recover oil and reduce oil mist from the exhaust.
Vacuum Pumps UK can assist with the supply of a new Becker U 4.630 F/K where the original pump specification needs to be retained.

DVP LX650
Closely matched 650 m³/h oil lubricated vacuum pump
DVP Alternative
Consider the DVP LX650
Where an exact Becker replacement is not essential, the DVP LX650 may provide a suitable closely matched alternative to the Becker U 4.630 F/K.
With a nominal capacity of 650 m³/h at 50Hz and 720 m³/h at 60Hz, the LX650 provides slightly more capacity at 50Hz and slightly less capacity at 60Hz than the Becker pump’s stated 624 / 732 m³/h performance.
Both pumps have a stated final pressure of 0.5 mbar absolute, making the LX650 a technically relevant option where its closely aligned capacity and higher motor rating are suitable for the application.
The LX650 is designed for high-capacity continuous service and is equipped with automatic lubrication, air cooling, an oil check valve, continuous gas ballast and shock mounts.
The LX650 has a higher motor rating than the Becker pump, so the electrical supply, starting arrangements, installation dimensions, connections and process requirements must be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Becker U 4.630 F/K and DVP LX650 Comparison
The comparison below shows the principal technical figures for each model. Final suitability should be checked against the machine, application and installation requirements.
| Specification | Becker U 4.630 F/K | DVP LX650 |
| Pump Technology | Oil lubricated rotary vane | Oil lubricated rotary vane |
| Nominal Capacity 50Hz | 624 m³/h | 650 m³/h |
| Nominal Capacity 60Hz | 732 m³/h | 720 m³/h |
| Ultimate / Final Pressure | 0.5 mbar absolute | 0.5 mbar absolute |
| Motor Power 50Hz | 15.0 kW | 18.5 kW |
| Motor Power 60Hz | 18.0 kW | 22.0 kW |
| Exhaust Oil Separation | Integrated oil separation | Integrated oil separation system |
Important: The LX650 has closely aligned capacity and a higher motor rating. Mounting dimensions, inlet position, connection size, motor voltage, electrical starting arrangements, operating pressure and process conditions should always be checked.
