Becker SV 1100/2 11 kW Side Channel Blower
The Becker SV 1100/2 11 kW is a high-differential double-stage side channel blower combining 520 m³/h nominal airflow with strong vacuum and positive-pressure performance.
At 50 Hz it provides maximum relative vacuum of -390 mbar and maximum positive pressure of +500 mbar. At 60 Hz the corresponding 13.2 kW motor increases nominal flow to 610 m³/h while retaining -390 mbar maximum vacuum and providing up to +410 mbar positive pressure.
The larger motor gives this SV 1100/2 configuration substantially greater differential capability than the 7.5 kW version while retaining the same nominal airflow, making it particularly useful for restrictive industrial systems.

High Airflow with up to +500 mbar Pressure
The Becker SV 1100/2 11 kW is designed for industrial systems requiring both substantial airflow and high differential capability. At 50 Hz it combines a nominal capacity of 520 m³/h with -390 mbar maximum relative vacuum and +500 mbar maximum positive pressure.
Although its nominal capacity is identical to the 7.5 kW SV 1100/2, the larger motor allows considerably greater system resistance to be overcome. This is particularly significant on positive-pressure duty, where the maximum 50 Hz differential increases from +260 mbar on the 7.5 kW version to +500 mbar on the 11 kW configuration.
The double-stage design redirects process air through the second side channel stage, transferring additional energy into the gas and allowing greater differential to be developed. This takes place without rubbing compression elements within the air path.
The compression chamber operates without lubricating oil, providing clean process air for industrial applications. The non-contact principle also means routine servicing requirements differ from positive-displacement pumps using rubbing vanes or lubricated compression chambers.
At these airflow and differential levels, correct system design is important. Pipework diameter, filtration, valves and process restriction should be considered alongside the blower performance curve to establish the correct operating point.
Becker SV 1100/2 11 kW Technical Specifications
The 11 kW 50 Hz configuration provides 520 m³/h nominal airflow. At 60 Hz the corresponding motor rating is 13.2 kW and nominal volume flow increases to 610 m³/h.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 520 m³/h | -390 mbar | +500 mbar | 11 kW | 125 kg |
| 60 Hz | 610 m³/h | -390 mbar | +410 mbar | 13.2 kW | 125 kg |
Vacuum and pressure figures are relative. Weight is 125 kg including motor.
Key Features of the SV 1100/2 11 kW
+500 mbar Pressure
High positive-pressure capability suits demanding conveying, blowing and restrictive process-air systems.
-390 mbar Vacuum
Strong vacuum performance combines with substantial airflow for demanding suction applications.
520 m³/h Airflow
Provides high process-air volume for larger industrial machinery and centralised systems.
Double-Stage Compression
Two successive side channel stages enable high differential without rubbing compression elements.
Oil-Free Process Air
No lubricating oil is required in the compression chamber, helping provide clean process airflow.
Sealed Bearings
Becker specifies sealed bearings, eliminating the requirement for bearing greasing during normal service.
Demanding Industrial Vacuum and Pressure Applications
The combination of 520 m³/h nominal airflow and high differential capability makes the 11 kW SV 1100/2 particularly suitable for larger or more restrictive industrial systems.
› Pneumatic conveying
› High-pressure process air
› Water aeration systems
› Industrial drying
› Restrictive process-air systems
› Vacuum lifting and handling

SV 1100/2 11 kW Supply and Duty Selection
Vacuum Pumps UK can assist with Becker SV 1100/2 11 kW supply for replacement machinery and new industrial vacuum or pressure systems.
For replacement requirements, send us clear photographs of both the blower and motor nameplates. This allows the exact SV 1100/2 motor configuration to be established before quotation.
For new installations, provide the required volume flow at the normal working vacuum or positive pressure. Pipework, filtration, valves and process restrictions can then be considered alongside the blower performance.
The 11 kW configuration should not be selected purely because it has the larger motor. Its principal advantage is the ability to operate against substantially greater differential, while nominal airflow remains the same as the 7.5 kW version.
Accessories for High-Differential SV 1100/2 Systems
At higher differential, correct system design and protection become particularly important. Filtration and pipework should be sized to support the required flow without creating unnecessary additional resistance.
Inlet Filters
Suitable filtration protects the blower from contamination while minimising avoidable inlet restriction.
Vacuum Relief Valves
Vacuum relief can limit excessive differential if suction-side restriction rises unexpectedly.
Pressure Relief Valves
Pressure relief is particularly important where discharge blockage could push a high-differential system beyond its intended duty.
Installation Accessories
Flexible connectors, non-return valves and correctly sized pipework can form part of a properly designed installation.
Becker SV 1100/2 11 kW Service, Repair and Spare Parts
The non-contact side channel principle reduces routine compression-element maintenance, but the condition of the motor, bearings and impeller remains important to reliable blower operation.
On high-differential installations, system restriction should also form part of any fault investigation. Dirty filtration, restricted pipework, closed valves or process changes can increase blower load and operating temperature.
Vacuum Pumps UK can assist with Becker SV servicing, performance investigation and workshop repair.
Blower Service
Technical support for Becker blower maintenance, performance checks and operating problems.
Blower Repair
Workshop investigation and repair assessment for noisy, damaged or under-performing Becker SV blowers.
Spare Parts
Becker replacement filters and spare parts are available through our sister company VacAir Superstore.
Becker SV 1100/2 11 kW Frequently Asked Questions
What airflow does the Becker SV 1100/2 11 kW provide?
Nominal volume flow is 520 m³/h at 50 Hz and 610 m³/h at 60 Hz.
What is the maximum vacuum?
Maximum relative vacuum is -390 mbar at both 50 Hz and 60 Hz.
What maximum positive pressure can it produce?
Maximum relative pressure is +500 mbar at 50 Hz and +410 mbar at 60 Hz.
How does the 11 kW version differ from the 7.5 kW SV 1100/2?
Both provide 520 m³/h nominal airflow at 50 Hz. The 11 kW version increases maximum vacuum from -350 to -390 mbar and maximum positive pressure from +260 to +500 mbar.
Why does the larger motor not increase the 50 Hz nominal airflow?
The additional motor power primarily allows the blower to operate against greater vacuum or pressure differential rather than increasing its nominal free-air capacity.
Is the SV 1100/2 oil-free?
Yes. No lubricating oil is required within the process-air compression chamber.
Can Vacuum Pumps UK help select the correct SV 1100/2 configuration?
Yes. Send us the required airflow and working vacuum or pressure, or provide the blower and motor nameplate details from an existing installation.
