Becker SV 500/2 5.5 kW Side Channel Blower
The Becker SV 500/2 5.5 kW is a double-stage side channel blower providing 260 m³/h nominal volume flow with strong vacuum performance and high differential capability.
At 50 Hz it provides maximum relative vacuum of -410 mbar and Becker’s detailed pressure-series data lists +370 mbar maximum positive pressure. At 60 Hz the corresponding 6.6 kW motor provides 305 m³/h, -400 mbar maximum vacuum and up to +530 mbar positive pressure.
This configuration is particularly notable at 60 Hz, where the larger motor allows substantially greater positive-pressure differential while maintaining the 305 m³/h nominal flow of the SV 500/2 platform.

High-Differential SV 500/2 Performance
The Becker SV 500/2 5.5 kW combines the 260 m³/h nominal 50 Hz capacity of the SV 500/2 platform with a larger motor configuration intended for demanding operating conditions.
On vacuum duty, maximum relative vacuum is -410 mbar at 50 Hz and -400 mbar at 60 Hz. At 60 Hz the positive-pressure capability reaches +530 mbar, giving this configuration particularly strong performance where substantial discharge differential is required.
The double-stage arrangement transfers energy into the process air through two successive side channels. This enables greater differential than a single-stage design while retaining the non-contact operating principle associated with side channel blowers.
No lubricating oil is required in the compression chamber and there are no rubbing vanes within the process-air path. This makes the blower suitable for industrial applications where clean process air and relatively low routine maintenance are important.
Actual airflow depends on the system operating point. Pipework, filters, valves, process equipment and other restrictions create differential, so the blower should always be considered against the required flow at the working vacuum or pressure.
Becker SV 500/2 5.5 kW Technical Specifications
The 5.5 kW motor is used at 50 Hz, while the corresponding 60 Hz motor rating is 6.6 kW. Nominal capacity increases from 260 m³/h to 305 m³/h at 60 Hz.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 260 m³/h | -410 mbar | +370 mbar | 5.5 kW | 67.5 kg |
| 60 Hz | 305 m³/h | -400 mbar | +530 mbar | 6.6 kW | 67.5 kg |
Vacuum and pressure figures are relative. Weight is 67.5 kg including motor.
Key Features of the SV 500/2 5.5 kW
Double-Stage Design
Two successive side channel stages provide the higher differential required by demanding industrial systems.
-410 mbar Vacuum
Strong 50 Hz suction performance suits vacuum applications with significant inlet and process resistance.
+530 mbar at 60 Hz
The 6.6 kW 60 Hz configuration provides particularly high positive-pressure differential for restrictive systems.
305 m³/h at 60 Hz
Higher frequency increases nominal airflow while the larger motor retains substantial differential capability.
Oil-Free Air Path
The process-air chamber operates without lubricating oil, helping provide clean airflow to the application.
Non-Contact Compression
No rubbing compression elements are used within the process-air path, contributing to low routine maintenance.
Industrial Applications for the SV 500/2 5.5 kW
The combination of double-stage compression, 260 m³/h nominal 50 Hz airflow and strong differential performance makes this SV 500/2 configuration suitable for demanding vacuum and pressure duties.
› Pneumatic conveying
› Blast-air systems
› Aeration equipment
› Industrial drying
› Restrictive process-air systems
› Vacuum lifting and handling
› Vacuum fixing and clamping
› Printing and paper machinery
› Packaging machinery
› General industrial machinery
SV 500/2 5.5 kW Supply and Duty Selection
Vacuum Pumps UK can assist with Becker SV 500/2 5.5 kW supply for replacement machinery and new industrial vacuum or pressure installations.
For an existing blower, send us clear photographs of both the Becker blower nameplate and motor plate. This helps identify the exact motor configuration before quotation.
For a new installation, provide the airflow required at the normal operating vacuum or positive pressure. Pipe diameter, pipe length, filters, valves and other significant restrictions can then be considered as part of the selection.
The larger motor should not be selected simply because it is the highest-power SV 500/2 configuration. The correct version depends on the actual airflow and differential required by the application.
Accessories for High-Differential SV 500/2 Systems
Correct system design becomes increasingly important as blower differential rises. Filtration, pipework and protection devices should be selected to support the required duty without introducing unnecessary restriction.
Inlet Filters
Suitable filtration protects the blower from contamination while minimising avoidable suction-side pressure loss.
Vacuum Relief Valves
Vacuum relief can limit excessive differential if the inlet or process becomes more restrictive than intended.
Pressure Relief Valves
Pressure relief is particularly relevant on high-differential duties where a blocked discharge can rapidly increase blower load.
Installation Accessories
Flexible connectors, non-return valves and correctly sized pipework can form part of a properly designed blower installation.
Becker SV 500/2 5.5 kW Service, Repair and Spare Parts
The SV 500/2 uses non-contact compression, but reliable operation still depends on the motor, bearings, impeller and the conditions created by the connected system.
On high-differential applications, dirty filtration, closed valves, restricted pipework or changes to the process can increase blower load and operating temperature. The complete installation should therefore be considered during fault diagnosis.
Vacuum Pumps UK can assist with Becker SV servicing, performance investigation and workshop repair.
Blower Service
Technical support for Becker blower maintenance, operating conditions and performance problems.
Blower Repair
Workshop investigation of noisy, damaged, overheating or under-performing Becker side channel blowers.
Spare Parts

Becker SV 500/2 5.5 kW Frequently Asked Questions
What airflow does the Becker SV 500/2 5.5 kW provide?
Nominal volume flow is 260 m³/h at 50 Hz and 305 m³/h at 60 Hz.
What maximum vacuum can it produce?
Maximum relative vacuum is -410 mbar at 50 Hz and -400 mbar at 60 Hz.
What is the positive-pressure performance?
Becker’s detailed pressure-series data lists +370 mbar maximum relative pressure at 50 Hz and +530 mbar at 60 Hz for the 5.5/6.6 kW configuration.
Why is the 60 Hz pressure considerably higher?
The 60 Hz configuration uses the corresponding 6.6 kW motor and Becker specifies substantially greater maximum positive-pressure differential for this operating condition.
Is the SV 500/2 oil-free?
Yes. The process-air compression chamber operates without lubricating oil.
Should I choose between the 4 kW and 5.5 kW versions from motor size alone?
No. Selection should be based on the airflow required at the actual operating vacuum or pressure and the electrical frequency of the installation.
Can Vacuum Pumps UK help identify an existing SV 500/2?
Yes. Send us the blower and motor nameplate details and we can assist with identification, supply, servicing or repair.
