Liquid Ring Vacuum in a Compact Package

The Elmo Rietschle L-BL2 is more than a standalone vacuum pump. It is a self-contained vacuum package incorporating the essential components required to operate the liquid ring pump efficiently.

This integrated design simplifies installation and reduces the amount of additional equipment normally associated with liquid ring vacuum systems.

The "Pump in a Box" concept
Pump, motor, liquid separation and cooling components are integrated into one compact system, providing a convenient ready-to-operate industrial vacuum solution.
Key Advantages

Designed for Challenging Vacuum Applications

The L-BL2 is particularly well suited to applications where moisture, vapours, condensate or continuous operating conditions can create problems for conventional vacuum pump technologies.

01

No External Water Supply

The integrated operating-fluid circuit eliminates the need for a continuous external water supply during normal operation.

02

Oil-Free Vacuum

Liquid ring operation provides completely oil-free compression for applications where process cleanliness is important.

03

Handles Vapours

Liquid ring technology is naturally suited to process gases containing moisture, vapour and condensation.

04

Low Mechanical Wear

Contact-free compression reduces internal mechanical wear and helps support long operating life.

05

Low Noise

The enclosed system is engineered for quiet operation in industrial production environments.

06

Cool, Clean Exhaust

Integrated separation and cooling help provide clean exhaust air while controlling operating temperature.

Integrated Cooling

Air-Cooled Liquid Ring Technology

Traditional liquid ring vacuum installations often require plant water, external cooling equipment and additional piping. The L-BL2 uses an integrated air-cooling system to simplify installation.

The discharge-air cooling arrangement limits the increase in surrounding room temperature to approximately 15K, even during extended operation.

This makes the L-BL2 an attractive option for facilities that want the operating advantages of liquid ring vacuum technology without installing a conventional water-cooled vacuum system.

Elmo Rietschle L-BL2 Frequently Asked Questions

Common questions about the L-BL2 compact liquid ring vacuum pump.

What is the Elmo Rietschle L-BL2?
The L-BL2 is a compact, self-contained liquid ring vacuum pump system. It combines an Elmo Rietschle L-BV liquid ring pump with the motor, separator, seal-water cooler and discharge-air cooler required for operation. This integrated configuration is often described as a "Pump in a Box."
Does the L-BL2 require a continuous water supply?
No. The L-BL2 uses an integrated operating-fluid and cooling system, allowing it to operate without the continuous external water consumption normally associated with many liquid ring vacuum pump installations.
Is the L-BL2 an oil-free vacuum pump?
Yes. The L-BL2 provides oil-free vacuum operation, making it attractive for applications where process cleanliness and contamination control are important.
How much vacuum can the L-BL2 produce?
Depending on the specific model and operating conditions, the L-BL2 series can achieve vacuum levels of up to approximately 95%. CompreVac can help determine the appropriate model for your required operating pressure and pumping capacity.
Can the L-BL2 handle moisture and vapours?
Yes. One of the major advantages of liquid ring vacuum technology is its ability to tolerate moist gases, vapours and condensation. This makes the L-BL2 suitable for process applications that can be challenging for other vacuum pump technologies.
Why is the L-BL2 called a "Pump in a Box"?
The term refers to its integrated design. Rather than installing a vacuum pump, separator, cooling system and associated components separately, the L-BL2 combines the essential components into a compact, ready-to-operate package.
Does the L-BL2 require much maintenance?
The liquid ring pump uses contact-free compression, which helps reduce internal mechanical wear. Routine inspection and preventive maintenance are still recommended to maintain cooling efficiency, operating-fluid condition and overall vacuum performance.
Can the L-BL2 operate continuously?
Yes. The L-BL2 is designed for demanding industrial applications and extended operating periods. Its integrated cooling system helps control operating temperatures during continuous-duty use.
What industries use liquid ring vacuum pumps?
Liquid ring vacuum pumps are commonly used in food processing, packaging, pharmaceutical production, chemical processing, vacuum drying and other industrial processes involving humid gases, vapours or condensable media.
How do I select the correct L-BL2 model?
Model selection depends on required vacuum level, pumping capacity, process gas, vapour load, inlet temperature, operating environment and duty cycle. CompreVac can review your application and help determine the appropriate Elmo Rietschle vacuum pump configuration.
Can CompreVac service Elmo Rietschle vacuum pumps?
CompreVac provides industrial vacuum pump service, repairs, rebuilds, preventive maintenance and application support. Contact CompreVac to discuss service requirements for your Elmo Rietschle vacuum equipment.
