Oil-free rotary vane vacuum technology supplied and supported by CompreVac.
Elmo Rietschle V-Series dry-running rotary vane pumps combine compact construction with oil-free operation. CompreVac provides equipment selection, replacement pumps, parts, application engineering and service support.
Elmo Rietschle dry-running rotary vane pumps use an eccentrically mounted rotor inside a cylindrical housing. Sliding vanes are located in slots within the rotor and move outward toward the housing as the rotor turns.
The spaces between adjacent vanes form variable-volume cells. Air enters as a cell expands, is trapped, and is then compressed as the available volume decreases before being discharged from the pump.
Because these V-Series models operate without lubricating oil in the compression chamber, they provide clean vacuum generation with compact construction and straightforward maintenance.
The V-Series provides proven vacuum technology for applications where compact size, simple operation and an oil-free compression chamber are priorities.
No lubricating oil is required inside the compression chamber or vacuum gas path.
Small physical size provides installation flexibility inside industrial machinery.
The V-Series is designed for smooth, comparatively quiet industrial vacuum operation.
Dry rotary vane construction provides straightforward routine service and vane replacement.
The V-Series progresses from compact low-flow machine vacuum pumps through larger dry rotary vane models delivering more than 90 CFM.
The V-VTE is the compact end of the Elmo Rietschle dry-running vane vacuum range. Its small footprint makes it particularly suitable for OEM machinery and applications requiring relatively low airflow.
The V-VTN range increases available pumping capacity while retaining the compact, dry-running rotary vane design. It is suitable for a wide range of industrial machinery and general vacuum applications.
The V-VTA range provides mid-capacity dry vacuum for packaging, printing, plastics, woodworking and other industrial machinery requiring a reliable continuous vacuum source.
The V-VTR provides the highest airflow range on this page, extending dry-running rotary vane technology into larger industrial machinery and centralized vacuum duties.
The rotor sits eccentrically inside the pump housing. As it rotates, centrifugal force pushes the sliding vanes outward against the cylinder wall, creating chambers whose volume changes continuously during rotation.
The compact design and clean dry gas path make V-Series pumps useful across a broad range of industrial machinery and automation applications.
Vacuum generation for handling, sealing, forming and automated packaging equipment.
Sheet transport, feeding, folding and post-press vacuum applications.
Vacuum holding, clamping and general woodworking machine applications.
Vacuum for forming, handling and industrial plastics machinery.
Compact vacuum generation integrated directly into automated production equipment.
Reliable dry vacuum for fixtures, handling systems and process equipment.
Elmo Rietschle manufactures industrial vacuum and pressure equipment using rotary vane, claw, screw, liquid ring and side-channel technologies.
CompreVac supplies Elmo Rietschle V-Series dry rotary vane vacuum pumps with application engineering, replacement equipment, parts and service support.
For a new application, CompreVac can evaluate required airflow, operating vacuum, duty cycle, inlet filtration, ambient conditions and system losses to help select the appropriate V-VTE, V-VTN, V-VTA or V-VTR model.
A dry rotary vane vacuum pump uses an eccentrically mounted rotor with sliding vanes to create changing-volume chambers that draw in and compress air without lubricating oil inside the compression chamber.
The V-VTE, V-VTN, V-VTA and V-VTR ranges shown here operate without lubricating oil in the compression chamber, providing a dry process gas path.
The current V-VTE, V-VTN, V-VTA and V-VTR product ranges shown on this page are published with an ultimate vacuum of approximately 150 mbar absolute, equivalent to about 25.5 inHg vacuum.
The primary difference is pumping capacity and physical size. V-VTE covers the smallest airflow range, followed by V-VTN and V-VTA, while V-VTR provides the largest airflow range shown on this page.
Yes. The vanes are wear components and should be inspected and replaced according to operating hours, application conditions and the manufacturer's maintenance recommendations.
These pumps are primarily intended for dry gases. Applications involving significant moisture, water vapour or liquid carryover may be better suited to another vacuum technology such as a liquid ring pump.
Typical applications include packaging, printing, plastics, woodworking and other industrial machinery requiring reliable dry vacuum.
Selection should consider required airflow at the actual operating vacuum, duty cycle, inlet conditions, filtration and pressure losses throughout the complete vacuum system.
Yes. CompreVac can review required airflow, vacuum level, duty cycle and system conditions to help select the appropriate Elmo Rietschle V-Series pump.
Yes. CompreVac provides troubleshooting, replacement parts, vane service, field support and workshop repair for industrial vacuum equipment.

Operating Principle V-Series
Pressure increase by volume reduction is the principle behind rotary vane operation. In a cylindrical housing a rotor is positioned eccentrically so that it is on the top almost touching the cylinder. Rotor blades or vanes as they are called, are positioned inside rotor slots.
When the rotor starts turning, due to centrifugal force the blades are thrown out and slide against the internal surface of the cylinder. In this way a cell is formed between two blades with a volume that changes constantly during rotation. Air enters from the inlet port into a cell until the rear blade reaches the far end of the inlet port. At this point the cell has achieved its maximum air volume. As the cell then moves away from the port its volume becomes smaller and smaller, the air is thus compressed and the pressure rises. This continues until the pressure in the cell exceeds that in the pressure chamber and the compressed air then exits through the outlet port.
Some models are fitted with exhaust valves which stop the backflow of this discharged air if the maximum pressure has been reached. In a vacuum pump the process is similar, but the cell gives decreasing pressure, and the chamber is at atmospheric pressure. With pressure-vacuum pumps the lower end of the inlet port(s) for the vacuum is moved forward. The cell can now be filled through second inlet. To avoid impairing the vacuum, this second inlet port is located about one cell segment away from the main suction port. The ratio between vacuum and pressure capacities can be influenced by the choice of inlet port.
