Becker U 5.71 Overview
The Becker U 5.71 is an oil lubricated rotary vane vacuum pump designed for continuous industrial service where a fine vacuum level and dependable performance are required.
With a nominal pumping speed of 70 m³/h at 50Hz and 84 m³/h at 60Hz, it is suitable for packaging machinery, process equipment, vacuum handling systems and other 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 5.71 where the original pump specification needs to be retained.

DVP LC60
Comparable 60 m³/h oil lubricated vacuum pump
Comparable DVP Alternatives
Consider the DVP LC60 or LC106
Where an exact Becker replacement is not essential, the DVP LC60 may provide a suitable and cost-effective alternative to the Becker U 5.71, while the DVP LC106 may be considered where a higher-capacity replacement option is preferred.
The DVP LC60 offers a nominal capacity of 60 m³/h at 50Hz and 72 m³/h at 60Hz, making it a closely aligned option for many applications. Its stated final pressure is 0.1 mbar absolute, which is comparable with the Becker U 5.71.
The DVP LC106 provides a larger nominal capacity of 100 m³/h at 50Hz and 120 m³/h at 60Hz. This can be useful where additional pumping speed is acceptable or beneficial, while still providing a stated final pressure of 0.1 mbar absolute.
Both DVP pumps are designed for continuous industrial operation and include an integrated oil damping and recovery system, incorporating a by-pass and automatic float-operated oil recovery valve, to help minimise oil vapour emissions from the exhaust.
An anti-suck-back device also helps prevent oil from being drawn back into the connected system if the pump stops while operating under vacuum. Mounting dimensions, inlet position, motor voltage, connections and installation arrangements must still be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Becker U 5.71, DVP LC60 and DVP LC106 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 5.71 | DVP LC60 | DVP LC106 |
| Pump Technology | Oil lubricated rotary vane | Oil lubricated rotary vane | Oil lubricated rotary vane |
| Nominal Capacity 50Hz | 70 m³/h | 60 m³/h | 100 m³/h |
| Nominal Capacity 60Hz | 84 m³/h | 72 m³/h | 120 m³/h |
| Maximum Vacuum | ≤0.1 mbar absolute | 0.1 mbar absolute | 0.1 mbar absolute |
| Motor Power 50Hz | 1.5 kW | 1.5 kW | 2.2 kW |
| Motor Power 60Hz | 1.8 kW | 1.8 kW | 2.6 kW |
| Oil Recovery System | Integrated oil separation | Integrated oil damping and recovery system | Integrated oil damping and recovery system |
Important: Mounting dimensions, inlet position, connection size, motor voltage, operating pressure and process conditions should always be checked.
Why Consider DVP Alternatives?
Many customers searching for a Becker U 5.71 require a reliable oil lubricated vacuum pump rather than a specific manufacturer.
LC60 Close Match
The LC60 provides 60 / 72 m³/h with the same 1.5 / 1.8 kW motor ratings, making it a closely aligned option.
LC106 Higher Capacity
The LC106 provides 100 / 120 m³/h where a larger-capacity replacement or upgrade option is preferred.
Fine Vacuum Capability
Both DVP models provide a stated final pressure of 0.1 mbar absolute, suitable for fine-vacuum applications.

Older Becker U 2.70, U 3.70, U 4.70 and U 5.70 Vacuum Pumps
The Becker U 5.71 follows several earlier Becker oil lubricated rotary vane vacuum pumps within the same general capacity range. Older models still found on packaging machinery, printing equipment and other industrial installations include the Becker U 2.70, Becker U 3.70, Becker U 4.70 and Becker U 5.70.
Vacuum Pumps UK can assist customers searching for information, servicing, spare parts or a suitable replacement for any of these older Becker vacuum pump models.
Becker U 2.70 Vacuum Pump
The Becker U 2.70 is an earlier oil lubricated rotary vane vacuum pump which may still be operating on older production machinery and industrial vacuum installations.
Becker U 3.70 Vacuum Pump
The Becker U 3.70 may still be found on packaging machinery, printing equipment and other applications requiring a dependable oil lubricated vacuum pump.
Becker U 4.70 Vacuum Pump
The Becker U 4.70 is an older-series Becker pump for which customers may require servicing, replacement components or advice on a suitable current pump.
Becker U 5.70 Vacuum Pump
The Becker U 5.70 directly preceded later models within this range and may still be installed on industrial machinery requiring reliable continuous vacuum performance.
Replacing an older Becker vacuum pump: A replacement should not be selected from the model number or pumping capacity alone. Mounting dimensions, inlet and exhaust positions, motor voltage, electrical arrangements, operating pressure and the requirements of the connected machinery must also be checked.
Depending on the application, we can assess a current Becker pump, the DVP LC60, the higher-capacity DVP LC106 or another suitable replacement pump.
Send us a photograph of the existing pump, its nameplate and the surrounding installation and we can advise on the most suitable option.
