Combined Pressure + Vacuum

One Dry-Running Claw Machine for Two Process Functions

Elmo Rietschle C-KLR pressure vacuum pumps generate vacuum at the inlet while simultaneously producing low-pressure compressed air at the discharge.

This allows one machine to perform two useful process functions. Vacuum can be used to grip, lift, hold or transport material while discharge air can be used for separation, release, blowing or other low-pressure duties.

The dry-running claw compression chamber uses synchronized, non-contacting rotors. No lubricating oil is required in the compression chamber, helping provide clean process air with comparatively low routine maintenance.

C-KLR Pressure Vacuum Advantages

Why Use a Combined Pressure Vacuum Claw Pump?

The Elmo Rietschle C-KLR combines the advantages of dry-running rotary claw technology with the ability to create vacuum and positive pressure simultaneously.

Vacuum + Pressure

One machine provides suction at the inlet and usable low-pressure air at the discharge.

Dry-Running Compression

No lubricating oil is required inside the compression chamber or process gas path.

Non-Contacting Rotors

Precisely synchronized claw rotors operate without touching one another during compression.

Low Routine Maintenance

Contact-free dry operation reduces wear inside the compression chamber for suitable industrial applications.

Pressure Vacuum Operation

How Does an Elmo Rietschle C-KLR Work?

Two claw-shaped rotors rotate in opposite directions inside the compression chamber. Their synchronized motion draws air through the inlet, traps it, compresses it and moves it toward the discharge without the rotors touching one another.

Vacuum Is Generated Air is drawn through the inlet to create the required process vacuum.
Air Is Trapped The synchronized claw rotors isolate a defined volume of process air.
Compression Occurs Rotor geometry reduces the trapped volume and increases pressure.
Pressure Air Is Discharged Low-pressure compressed air exits the pump for use elsewhere in the machine.
Industrial Applications

Where Are C-KLR Pressure Vacuum Pumps Used?

Combined pressure and vacuum technology is particularly useful on machines requiring suction and blowing or separation from the same air system.

Printing Machinery

Vacuum sheet pickup combined with pressure-air sheet separation and feeding.

Paper Handling

Vacuum gripping, transport and positioning with low-pressure air separation.

Packaging Equipment

Vacuum handling with pressure air for separation, release and machine functions.

Material Handling

Vacuum gripping combined with positive-pressure air for product release.

Machine Automation

One pump can provide two air functions within automated industrial machinery.

OEM Equipment

Compact pressure vacuum technology for integration into purpose-built machines.

Elmo Rietschle + CompreVac

Pressure Vacuum Technology From CompreVac

Elmo Rietschle manufactures industrial claw, rotary vane, screw, side-channel and liquid-ring vacuum and pressure technologies.

CompreVac supplies Elmo Rietschle C-KLR pressure vacuum pumps with local application support, system engineering, parts and service support.

For a new installation, CompreVac can evaluate required airflow, vacuum, positive pressure, operating cycle, inlet conditions, controls and piping as part of the complete application rather than simply selecting a pump from nominal capacity.

Frequently Asked Questions

Elmo Rietschle C-KLR Pressure Vacuum Pump FAQs

What is a pressure vacuum pump?

A pressure vacuum pump creates vacuum at its inlet while simultaneously providing positive pressure at its discharge. This allows one machine to perform both suction and blowing functions.

What is the Elmo Rietschle C-KLR?

The C-KLR is a dry-running rotary claw pressure vacuum pump designed for industrial applications requiring vacuum and low-pressure compressed air at the same time.

Are C-KLR pumps oil-free?

The compression chamber operates without lubricating oil in the process gas path. The claw rotors operate dry and without contacting one another.

What is the difference between a C-KLR and a standard claw vacuum pump?

A standard claw vacuum pump is primarily selected for suction duty. The C-KLR is designed so that both the vacuum inlet and the positive-pressure discharge can be used as part of the process.

What C-KLR models are available?

This page covers the Elmo Rietschle C-KLR 80 and C-KLR 140 pressure vacuum claw pumps.

Where are C-KLR pressure vacuum pumps commonly used?

Typical applications include printing machinery, paper handling, packaging, material handling, automated machinery and OEM equipment requiring both vacuum and low-pressure air.

Why are pressure vacuum pumps useful in printing and paper handling?

Vacuum can be used to pick up and transport sheets while low-pressure air from the discharge can help separate the next sheet, allowing two related functions to be supplied from one machine.

How do I select between the C-KLR 80 and C-KLR 140?

Selection depends on required airflow, operating vacuum, discharge pressure, duty cycle, inlet conditions and pressure losses throughout the complete system.

Can CompreVac help size a C-KLR pressure vacuum pump?

Yes. CompreVac can review the required vacuum, pressure, airflow and operating conditions and help select the appropriate Elmo Rietschle C-KLR model.

Does CompreVac service Elmo Rietschle equipment?

Yes. CompreVac provides industrial vacuum and pressure equipment troubleshooting, parts, field service and workshop repair support.
