Becker U 4.400 SA/K Overview
The Becker U 4.400 SA/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 435 m³/h at 50Hz and 508 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 4.400 SA/K where the original pump specification needs to be retained.

DVP LX550
Higher-capacity 550 m³/h oil lubricated vacuum pump
DVP Alternative
Consider the DVP LX550
Where an exact Becker replacement is not essential, the DVP LX550 may provide a suitable high-capacity alternative to the Becker U 4.400 SA/K.
With a nominal capacity of 550 m³/h at 50Hz and 600 m³/h at 60Hz, the LX550 provides additional pumping capacity compared with the Becker pump’s stated 435 / 508 m³/h performance.
The DVP LX550 has a stated final pressure of 0.5 mbar absolute, compared with 3.0 mbar absolute for the Becker pump. It therefore provides a deeper vacuum level as well as increased pumping capacity, where the larger motor and installation requirements are suitable for the application.
The LX550 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 LX550 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 4.400 SA/K and DVP LX550 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 4.400 SA/K | DVP LX550 |
| Pump Technology | Oil lubricated rotary vane | Oil lubricated rotary vane |
| Nominal Capacity 50Hz | 435 m³/h | 550 m³/h |
| Nominal Capacity 60Hz | 508 m³/h | 600 m³/h |
| Ultimate / Final Pressure | 3.0 mbar absolute | 0.5 mbar absolute |
| Motor Power 50Hz | 11.0 kW | 15.0 kW |
| Motor Power 60Hz | 13.2 kW | 18.0 kW |
| Exhaust Oil Separation | Integrated oil separation | Integrated oil separation system |
Important: The LX550 provides more capacity and has a higher motor rating. Mounting dimensions, inlet position, connection size, motor voltage, electrical starting arrangements, operating pressure and process conditions should always be checked.
