Becker SV500/2 3kW Side Channel Vacuum Pump
The Becker SV500/2 3kW is a two-stage side channel vacuum pump delivering 260 m³/h nominal capacity at 50 Hz with maximum relative vacuum of -280 mbar.
This version of the SV500/2 combines relatively high airflow with moderate vacuum differential. Rather than being configured for the deepest possible vacuum from the SV500/2 platform, the 3kW model is particularly relevant to applications requiring a substantial and continuous volume of oil-free suction air.
At 60 Hz, the corresponding 3.6kW specification provides 305 m³/h with maximum relative vacuum of -250 mbar. The complete unit weighs approximately 58 kg with motor.

High Airflow Two-Stage Vacuum Performance
The 3kW Becker SV500/2 has a performance profile centred on moving a relatively large volume of air while maintaining useful vacuum differential. At 50 Hz it provides 260 m³/h nominal capacity and reaches a maximum relative vacuum of -280 mbar.
This makes the specification distinctly different from the higher-powered SV500/2 variants. For many industrial processes, the requirement is not necessarily the deepest vacuum available; maintaining sufficient airflow at the required working vacuum can be considerably more important.
The SV500/2 uses regenerative side channel technology. Air entering the pump is accelerated by the rotating impeller and repeatedly circulated through the side channel, progressively increasing the pressure differential.
Its two-stage arrangement allows the air to pass through successive regenerative compression sections before discharge. The result is continuous vacuum generation without sliding vanes making contact with the compression chamber.
The compression principle is completely oil-free within the process-air path. This avoids the need for lubricating oil to create the vacuum and makes the SV500/2 suitable for applications where clean, continuous suction airflow is required.
Becker SV500/2 3kW Technical Specification
At 50 Hz, the 3kW SV500/2 provides 260 m³/h nominal volume flow and maximum relative vacuum of -280 mbar. At 60 Hz, motor power increases to 3.6kW, nominal capacity to 305 m³/h and maximum relative vacuum is -250 mbar.
| Frequency | Model | Stage | Nominal Capacity | Maximum Vacuum | Motor Power |
| 50 Hz | SV500/2 | Two Stage | 260 m³/h | -280 mbar | 3kW |
| 60 Hz | SV500/2 | Two Stage | 305 m³/h | -250 mbar | 3.6kW |
The complete pump weighs approximately 58 kg with motor. Nominal volume flow and maximum vacuum represent different operating points; actual airflow depends upon the vacuum level and resistance created by the application.
When selecting a replacement pump, the required airflow at the normal operating vacuum should therefore be considered alongside the maximum figures.
SV500/2 Design and Operating Features
Two-Stage Design
Successive regenerative stages provide the vacuum differential while maintaining continuous airflow through the pump.
260 m³/h Capacity
The 50 Hz configuration provides substantial nominal airflow for industrial machinery and process applications.
Oil-Free Compression
No lubricating oil is required within the process-air chamber to generate vacuum.
Non-Contact Operation
Regenerative compression avoids rubbing carbon vanes and other contacting compression components.
Integrated Silencers
Becker incorporates inlet and discharge silencers into the SV500/2 design to help control operating noise.
Sealed Bearings
Sealed bearing construction eliminates the requirement for routine bearing greasing.
Applications for the Becker SV500/2 3kW
With 260 m³/h nominal airflow and -280 mbar maximum relative vacuum at 50 Hz, this version of the SV500/2 is particularly suited to applications requiring continuous suction airflow at moderate vacuum levels.
› Printing and paper machinery
› Packaging equipment
› Industrial extraction
› Process vacuum applications
› Production machinery
› General mechanical engineering
For new installations, the required operating airflow and vacuum should be established before selecting the pump. Pipework diameter, filtration, process restriction and duty conditions can all influence actual system performance.
Replacing an Existing SV500/2
The SV500/2 is available in different motor and performance configurations, so identifying an existing pump simply as an “SV500/2” is not always sufficient when selecting a replacement.
The 3kW version covered on this page provides 260 m³/h and -280 mbar maximum relative vacuum at 50 Hz. Other SV500/2 configurations can have substantially different vacuum performance despite sharing the same basic model designation.
For an existing installation, send us photographs of the complete pump together with clear images of the Becker identification plate and motor nameplate. If possible, also provide details of the application and normal operating vacuum.
Checking these details helps avoid selecting a replacement based only on the SV500/2 model family when the actual motor and performance specification may differ.
SV500/2 Accessories and System Protection
Correct filtration and unrestricted airflow are important to side channel vacuum pump operation. Excessive inlet restriction can alter performance and increase operating temperature.
Vacuum Filters
Suitable inlet filtration protects the pump from process contamination while maintaining the required airflow.
Vacuum Relief
Appropriate relief protection can prevent the pump from operating at excessive vacuum if system conditions change.
Silencing
The SV500/2 incorporates inlet and discharge silencers, with additional system noise control available where required.
Pipework
Correctly sized pipework, valves and flexible connections help minimise unnecessary restriction and vacuum losses.
Becker SV500/2 Service and Repair
The SV500/2 uses non-contact regenerative compression and therefore does not have the carbon vane wear associated with dry-running rotary vane vacuum pumps. Bearings, motors and other mechanical components can nevertheless require attention during a long operating life.
Changes in noise, vibration, temperature or vacuum performance should be investigated. Reduced suction can also result from blocked filters, pipework restrictions, leaks or changes elsewhere in the vacuum system rather than an internal pump fault.
Vacuum Pumps UK can inspect Becker side channel vacuum pumps in our workshop, diagnose reported problems and provide service and repair support.
Workshop Inspection
Assessment of the existing Becker pump and investigation of mechanical or performance issues.
Service & Repair
Repair options can be considered following inspection of the pump and its mechanical condition.
Becker Spares
Becker filters and replacement components can also be supplied through VacAir Superstore.
