Deep-vacuum rotary vane pumps for industrial processes requiring high vacuum, dependable continuous operation and robust oil-sealed compression. CompreVac supplies and supports the Elmo Rietschle V-VCS, V-VGD, V-VCB, V-VCA, V-VCE and V-VC ranges throughout Canada.
Deep-vacuum rotary vane technology supplied and supported by CompreVac.
Elmo Rietschle oil-lubricated rotary vane pumps are designed for applications requiring deeper vacuum than typical dry-running vane pumps. CompreVac provides pump selection, replacement equipment, parts and service.
Oil-lubricated rotary vane pumps use an eccentrically mounted rotor with sliding vanes to create changing-volume compression chambers. Oil provides sealing, lubrication and cooling within the pump.
As the rotor turns, gas enters the expanding chamber, becomes trapped, is compressed as chamber volume decreases and is then discharged through the exhaust system.
The oil seal allows many V-Series pumps to achieve substantially deeper vacuum levels than dry-running vane designs, making them suitable for vacuum packaging, process vacuum, degassing and other demanding applications.
Oil-lubricated vane technology remains one of the most widely used industrial vacuum principles where deep vacuum and dependable operation are required.
Oil sealing allows substantially lower absolute pressure than typical dry vane pumps.
Proven rotary vane construction is suited to continuous industrial vacuum service.
Integrated oil separation and compact construction support smooth, quiet operation.
The V-Series extends from compact packaging pumps to large industrial vacuum machines.
From compact vacuum packaging pumps to high-capacity V-VC systems, CompreVac can match pump size and vacuum capability to the process.
The V-VCS range is the modern heavy-duty oil-lubricated rotary vane platform, developed for industrial applications requiring high vacuum, robust construction and lower installed size, noise and weight.
The V-VGD range provides compact oil-flooded rotary vane vacuum with operator-selectable fine or coarse vacuum settings and very quiet operation.
The compact V-VCB range is designed particularly for smaller vacuum packaging machines and similar equipment requiring deep vacuum from a compact oil-lubricated pump.
The V-VCA and V-VCE provide mid-capacity oil-flooded vacuum in a compact flange-motor configuration with standard filtration, non-return protection, gas ballast and oil separation.
The V-VC is one of the established Elmo Rietschle oil-lubricated rotary vane families, covering applications from medium industrial vacuum through large centralized and process vacuum systems.
An eccentrically mounted rotor turns inside a cylindrical housing. Sliding vanes form changing-volume chambers while oil seals clearances, lubricates internal components and assists with heat removal.
Deep vacuum capability makes oil-sealed rotary vane technology suitable for many industrial processes where dry vane technology cannot reach the required operating pressure.
Deep evacuation for chamber packaging machines and food packaging systems.
Vacuum packaging, deaeration and selected production processes.
Vacuum forming, extrusion, degassing and industrial plastics machinery.
Vacuum generation for presses, converting equipment and process machinery.
Industrial evacuation and degassing requiring deeper absolute pressure.
Larger V-VC pumps can support engineered centralized industrial vacuum systems.
Elmo Rietschle manufactures both dry-running and oil-lubricated rotary vane vacuum pumps, allowing technology to be matched to the required vacuum level and process conditions.
CompreVac supplies Elmo Rietschle oil-lubricated vane pumps with application engineering, replacement equipment, parts and service support.
For a new installation, CompreVac can evaluate required pumping speed, operating vacuum, duty cycle, inlet contamination, gas ballast requirements, filtration and oil separation as part of the complete vacuum system.
It is a rotary vane vacuum pump that uses oil to lubricate, cool and seal the internal compression chambers, allowing the pump to achieve deep vacuum levels.
Oil-lubricated vane pumps generally achieve substantially deeper vacuum than dry-running vane pumps, making them more suitable for high-vacuum industrial processes and vacuum packaging.
The exact ultimate vacuum depends on the model. Smaller V-VGD models can reach approximately 29.86 inHg in fine-vacuum mode, while selected larger oil-flooded ranges can operate at very low absolute pressures.
V-VGD is a compact low-capacity oil-flooded range, while the V-VC family extends into much larger industrial pumping capacities and centralized vacuum applications.
The V-VCB range is specifically designed for compact vacuum packaging equipment and similar low-capacity deep-vacuum applications.
A gas ballast allows a controlled amount of air into the compression stage to help reduce condensation of water vapour or other condensable vapours inside the pump.
Yes. Oil is a working component of the pump and must be checked and changed according to operating hours, process conditions and the manufacturer's maintenance recommendations.

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.
With available volume flows ranging from 40 to 1500 m³/h, the VCS models are tailored to boost the established performance parameters of this reliable technology. This series is characterized by low ownership costs and a design that emphasizes reduced weight, noise, and size, making the pumps highly adaptable for various industrial applications. The V-VCS series offers a seamless and efficient solution for those seeking robust vacuum performance.
