DVP CBL Vacuum Booster Systems
DVP CBL systems combine oil lubricated rotary vane primary pumps with BCA lobe vacuum boosters to deliver rapid evacuation, high pumping capacity and lower final pressure for demanding industrial processes.
Available in configurations using one, two or three primary pumps, the CBL range provides stated capacities from 246 to 3,125 m³/h at 5 mbar and final pressures as low as 0.006 mbar absolute.

DVP CBL System Overview
In a CBL system, the BCA lobe pump operates in series with one or more DVP oil lubricated rotary vane primary pumps. The primary pump initially evacuates the process and establishes the operating conditions required for the lobe booster to contribute effectively.
Once operating together, the booster increases the available pumping speed within its working pressure range. This can reduce evacuation time and allow the system to reach a substantially lower final pressure than the primary pump could normally achieve alone.
DVP states that a correctly selected CBL system can normally achieve a final pressure approximately ten times lower than the primary pump by itself, while also accelerating the evacuation of a closed vessel or process chamber.

The figures below are the stated DVP performance data supplied for the current standard CBL configurations. Final system selection should be confirmed against the complete process duty.

How a CBL Booster System Works
A lobe booster is not normally used as a standalone vacuum pump in this type of installation. It is supported by the primary rotary vane pump, which handles the gas discharged by the booster and maintains the pressure differential required for reliable operation.
1. Initial Evacuation
The oil lubricated primary pump begins evacuating the chamber, pipework or process equipment from atmospheric pressure.
2. Booster Operation
As the pressure falls into the correct operating range, the BCA lobe booster increases the effective pumping speed of the system.
3. Faster Pump-Down
The increased pumping capacity can shorten the time required to evacuate a closed volume and help improve production cycle times.
4. Lower Final Pressure
The combined system can achieve a lower ultimate pressure than the primary rotary vane pump would normally reach on its own.
DVP AdaptShield Technology
AdaptShield is DVP’s self-adaptive control and protection system for the CBL range. It manages the relationship between the primary pump and lobe booster while responding automatically to changing process conditions.
The system is designed to protect the installation during critical events such as plant leakage, reduced performance and excessive operating temperature. Instead of relying solely on a conventional mechanical bypass, AdaptShield adjusts operation electronically according to system demand.
DVP states that this approach can reduce absorbed energy by up to 13% compared with systems without AdaptShield and by up to 20% compared with systems using a mechanical bypass. Actual consumption will depend on the selected system, process conditions, operating pressure and duty cycle.
AdaptShield System Benefits
Automatic Protection
The system responds to conditions including leakage, loss of performance and excessive temperature to help protect the booster installation.
Adaptive Energy Use
Operating parameters are adjusted according to actual system conditions rather than depending entirely on a fixed mechanical bypass arrangement.
Rapid Pressure Response
AdaptShield is designed to react quickly to pressure variation and help the CBL system adapt to changing process demand.
Remote Monitoring
Operating parameters, fault identification and remote support functions can be accessed through DVP’s compatible smartphone monitoring system.
Typical CBL Applications
DVP CBL systems are intended for industrial processes requiring high pumping speed at low pressure, rapid evacuation of a closed volume or a lower final pressure than a conventional primary pump can provide alone.
› Pharmaceutical production and processing
› Vacuum metal treatment
› Heat treatment and vacuum furnaces
› Electrical transformer oil degassing
› Industrial chamber evacuation
› Drying and process evacuation
› OEM vacuum equipment
› General high-capacity industrial vacuum
Why Choose a DVP CBL System?
A CBL system may be appropriate where a single oil lubricated rotary vane pump cannot achieve the required evacuation time, operating capacity or final pressure economically.
The modular range allows DVP to combine a suitable BCA lobe booster with one or more LC primary pumps. This provides a selection of standard systems covering different capacities, motor powers and process requirements.
Vacuum Pumps UK can support the project from initial pump sizing through to installation planning, accessories, commissioning requirements, servicing and long-term spare-parts support.
Information Required to Select a CBL System
Booster systems should be selected against the complete application rather than nominal capacity alone. To help us assess the duty, please provide as much of the following information as possible.
› Chamber or vessel volume
› Required pump-down time
› Required operating pressure
› Required final pressure
› Expected gas or vapour load
› Process temperature
› Operating cycle and daily running hours
› Available electrical supply
› Pipework size and installation layout
› Details of any existing vacuum equipment
New System or Replacement Installation?
Designing a New Process?
We can review the chamber volume, target pressure, evacuation time, process gas load and operating cycle before recommending a suitable system.
Replacing an Existing Booster?
Send us the existing primary and booster pump details, together with photographs of the nameplates and installation, so that we can compare the duty.
Improving Pump-Down Time?
Where production is limited by slow chamber evacuation, a correctly sized booster system may reduce pump-down time without relying on a very large primary pump alone.
Need a Lower Pressure?
A CBL system may provide the additional low-pressure performance required where the existing primary pump cannot reach the process target by itself.
Not Sure Which CBL Configuration You Need?
CBL systems should be selected from the actual application data rather than simply matching an existing motor size or nominal pumping speed.
Send us the required pressure, chamber volume, pump-down time, process details and any existing pump information. We will assess the duty and advise which DVP configuration should be considered.

DVP CBL Frequently Asked Questions
What is a DVP CBL vacuum system?
A CBL system combines one or more DVP oil lubricated rotary vane primary pumps with a BCA lobe vacuum booster to provide higher pumping speed at low pressure and a lower final pressure.
Can a BCA lobe booster operate by itself?
Not in this CBL arrangement. The BCA booster is installed in series with a suitable primary vacuum pump, which supports its operation and handles the discharged gas.
What capacity does the CBL range provide?
The stated range extends from 246 m³/h to 3,125 m³/h at 5 mbar, depending on model, frequency and operating conditions.
What final pressure can a CBL system achieve?
The stated final pressure is 0.006 mbar absolute for the CBL 106/300 and 0.009 mbar absolute for the other listed configurations.
Does a CBL system evacuate a chamber faster?
Potentially, yes. The lobe booster increases effective pumping speed within its operating range and can therefore shorten the evacuation time of a closed volume when correctly selected.
What is AdaptShield?
AdaptShield is DVP’s self-adaptive control and protection technology for CBL systems. It responds to changing system conditions and helps protect against events including leakage, reduced performance and excessive temperature.
How much energy can AdaptShield save?
DVP states savings of up to 13% compared with systems without AdaptShield and up to 20% compared with systems using a mechanical bypass. Actual savings depend on the installation and operating duty.
What information is needed to select a CBL system?
Important information includes vessel volume, required pump-down time, operating pressure, final pressure, process gas or vapour load, operating cycle, electrical supply and installation details.
What industries use CBL booster systems?
Typical applications include pharmaceutical production, vacuum metal treatment, transformer oil degassing, food processing, food packaging and other industrial processes requiring high pumping capacity at low pressure.
