This article aims to describe the main features of the vane pump technology, how it works, its advantages and disadvantages, and where it is most commonly used. Finally, we will briefly mention the Fluid-o-Tech vane pumps.

Rotary vane pumps are a type of positive displacement pump. Like all positive displacement pumps, the flow rate is always directly proportional to the speed.

Vane pumps are available with different types of vane: sliding, flexible, oscillating, rotating, and external vanes. The vane pumps are known for their dry-priming, easy maintenance, and good suction characteristics throughout the life of the pump.

A splined rotor is supported eccentrically in a cycloidal cam. The rotor sits close to the cam wall to form a crescent-shaped cavity. The rotor is sealed in the cam by two side plates. The vanes or blades fit into the rotor cavities. When the rotor rotates and fluid enters the pump, the centrifugal force, the hydraulic pressure, and/or the pushrods push the vanes towards the housing walls. The tight seal between the vanes, the rotor, the cam, and the side plate makes this technology powerful for good suction, which is common to the vane pumping principle.

The housing and cam force the fluid into the pumping chamber through holes in the cam (small red arrow on the bottom of the pump). The fluid enters the pockets created by the vanes, the rotor, the cam, and the side plate.

As the rotor continues to spin, the vanes sweep the fluid to the opposite side of the crescent where it is squeezed through the cam discharge holes as the vane approaches the point of the crescent. The fluid then exits through the discharge port.

The rotary vane pump is very versatile and can be used in a variety of sectors and applications, from dosing to transferring and repressurizing fluids. Depending on the choice of materials, rotary vane pumps can handle a wide range of clean fluids.

Fluid-o-Tech is able to supply a wide range of rotary vane pumps covering a variety of applications in different sectors. In stainless steel, low-lead brass, technopolymer, direct coupled, magnetic or electromagnetic drive at variable speed, our pumps cover a flow rate range from 30 to 2200 l/h at pressures up to 18 bar. The built-in safety valve, available on request, limits the pressure to protect the pump and the hydraulic circuit.

The Fluid-o-Tech rotary vane pumps, WRAS or NSF certified for use with potable water, are the reference choice in the market of espresso machines and beverage dispensers for professional use.

Oil sealed or as popularly referred to as Rotary vane pumps are the main pumps in most heat treatment vacuum systems. They can also be called ‘backing’ pumps when incorporated with a booster pump, or with both a secondary (‘high vacuum’) pump and booster, turbo, cryo, and diffusion are all popular styles. In cases where a high vacuum is not needed, and a slower pump-down is sustainable, a rotary vane pump can be used independently.

They come in two-stage designs, which use two rotors sequentially to the pump. Single-stage designs offer a vacuum of 3 x 10-2 Torr (4 x 10-2 mbar), whereas two-stage designs can reach up to 3 x 10-3 Torr (4 x 10-3 mbar).

As a result of how rotary vane pumps have become prevalent, users and industrial vacuum equipment designers need to understand how these pumps work. This article series will encompass principles of operation, pump oils, pump designs, two-stage versus single-stage pump designs, common accessories, contamination and gas ballast (automatic and manual), applications, troubleshooting, and pump maintenance.

Out of all the vacuum pump innovations, rotary vane pumps are hugely deemed to be wet and positive displacement pumps. They are usually called ‘wet’ pumps because the gas that’s being pumped is brought into contact with oil used as a lubricant to provide the seal.

Because of this, oil is selected carefully and specially made for the application. Positive displacement means that the pump functions by trapping a volume of gas mechanically and moving it across the pump, which creates a low-pressure zone on the input side.

Rotary vane pumps are built in such a way that the pump’s stator is doused in oil and has a rotor that is mounted eccentrically. The rotor comes with two vanes that slide in diametrically opposing slots. The vanes sometimes can be spring-loaded, but in most cases, they will depend on centrifugal force to assist in pushing outward against the stator wall. With the rotor continually turning, the blade tips will be exposed to the stator wall.

The whole assembly is assembled and machined with tight tolerances, such that the space between the stator wall and rotor’s top (commonly known as ‘Dou seal’) is roughly 0.025 mm (1.0 mils). Oil is filled in this seal to provide a seal between the outlet and inlet sides. Oil from the reservoir is circulated into the pump interior and is depleted through the exhaust valve alongside the pumped gas.

The optimal pressure that can be attained by the pump is restricted by back-leakage through the Duo seal and lubricating oil outgassing. The outlet pressure can reach up to 1000 mbar (750 Torr) while the inlet can be as low as .01 mbar (0.0075 Torr), meaning the pressure differentials across the oil-filled is approximately 100,000:1 (1000:0.01). When there are pressure differentials larger than this, back-leakage across the seal will happen, representing one of the restricting factors in the maximum vacuum attainable by rotary vane pumps.

The exhaust valve is among the most fundamental components in a rotary vane pump, given how several ports feed it. One frequently used valve design utilizes a fluoro-elastomer or elastomer (artificial rubber), coupled with a metal backing plate. The role of the metal backing plate is limiting the motion of the elastomer valve part. There are all metal valves and don’t have an elastomer, but this design is prone to experience a phenomenon referred to as ‘suck-back’ when the pump halts under vacuum. Given how the valve doesn’t have an elastomer, oil leaks past it and gets ‘sucked’ back through the pump and into the furnace or vacuum chamber. Considering that with every rotation, the valve opens up and closes, it offers a source of noise and is more prone to wear, regardless if an elastomer is used or not. Given a rotational speed of 1750 RPM, for instance, the valve will close and open 2.5 million times after every 24 hours and at a frequency of 29 Hz. The valve functions mechanically and is forced to open by the in-built pressure created inside the pump and closed with atmospheric pressure.

Rotary pumps are lubricated using oil, which offers a seal between the low and high-pressure pump sides and lubricates the pump"s bearings and other rotating parts. Traditional pump designs that use the circulation of lubricating oil depended on a vacuum feed distribution system where the vacuum created by the pump was also used to draw lubricating oil via rotor bearings. Some pumps utilize spring-loaded lip shaft seals on every side of the rotor shaft. This is a more dynamic seal style which will need lubrication.

Even though the feed oil system is still being utilized, more contemporary pumps utilize an independent oil pump to circulate the oil through passages machined in the stator to the seals and rotor bearings. When the vacuum pump is working, its rotation in the process rotates the oil pump that is mounted to the shaft and creates a positive oil feed pressure of 300 Torr (0.4 bar) above atmospheric pressure. This pressure, in turn, lists the spring-loaded elastomer disc, which enables oil to flow into a trough feeding the rotor bearings and pump interior as well as the vacuum pump vanes. As the vacuum pump comes to a stop, the oil pump pressure isn’t available to force open the elastomer disc and thus closes, avoiding oil suck back through the pump and directly in the vacuum chamber. Whether the oil pump has been used or not, the excess oil is depleted from the exhaust valve"s pumping mechanism.

Vacuum pumps that utilize a separate pump can be integrated with an inlet isolation valve that is hydraulically operated. Here, the circulated oil is directed to a piston that is connected to an inlet valve and situated where the gas gains entry into the pump when coming from the vacuum chamber. The piston utilizes the hydraulic pressure created by the oil pump to open the inlet valve and allow gas to gain entry into the pump from the chamber. The valve spring loads and uses an elastomer seal to hinder the passage of gas within 0.5 seconds. This offers extra protection against suck back in the vacuum chamber.

When it comes to matters concerning oil-sealed rotary vane pumps, a lot more can be said, but the important thing is recognizing the vacuum furnace’s overall performance.  It"s integral that you are aware of how they function and how to use them correctly. Make sure you"ve changed the oil after every month and employ proper measures to maintain and take care of them, and you will be assured of numerous other years of trouble-free pump functioning.

Rotary-vane pumps are positive displacement machines capable of handling lubricating and other low-viscosity fluids in low to medium volumes at low pressures and, in some applications, relatively viscous fluids. Sometimes called carbonator pumps for their use in making carbonated soft drinks, the design has traditionally been used as well in automotive applications. They have an ability to develop a good vacuum and are often used to transfer LNG as well as some solvents. Their various permutations are described here along with a discussion of their operation and common applications. For information on other pumps, please see our Pumps Buyers Guide.

These pumps combine an eccentric ring and a rotor fitted with slots. The slots hold the vanes which are capable of moving radially as the rotor turns in the ring. As the vanes revolve past the suction port, they move outward, creating a volume defined by consecutive vanes, the rotor, and the ring wall. This volume draws fluid in and is then sealed off as it moves past the suction port. On the discharge side, the combined eccentricity of ring and rotor pushes the vanes into the slots, decreasing the volume and forcing the fluid out through a discharge port. Both suction and discharge ports, or galleys, are often kidney-shaped and fill from the sides.

Vanes are often constructed from carbon graphite to minimize wear where low-lubricity fluids are handled. Centrifugal force and fluid pressure are the common means of extending the vanes out to the ring walls but positive methods of extending them such as rods are used in certain designs. The vanes themselves are able to compensate for wear and most designs allow for easy vane replacement, making sliding-vane pumps low maintenance.

Another design employs pivoting vanes which swing outward through centrifugal force to form volumes which decrease as they move past the discharge openings. External-vane pumps are also produced.

Sliding-vane pumps can be fixed-output designs or they can be manufactured with an ability to vary the eccentricity between rotor and ring. This gives variable-rate control from a constant input rpm. Pressure-compensated pumps are used in many fluid-power applications.

Like the sliding-vane pump, the flexible-vane pump relies on eccentric motion developed between a revolving rotor and a fixed ring to move fluid between suction and discharge ports. Instead of slots and rigid vanes, though, the flexible vane pump employs vanes that are molded from a flexible material which deforms as the rotor makes its circuit. This produces cavities which expand on the suction side and collapse on the discharge side. The design is useful for moving fluids that contain particles or solids as there are no critical internal clearances where such particles might lodge. Impellers are manufactured from various rubber compounds including EPDM and silicone for compatibility with a variety of products. Flexible-vane pumps are considered to be low shear.

As mentioned, soda dispensers use sliding-vane pumps to move water into pressurized CO2 tanks. Commercial espresso machines use them as well to force heated water through densely packed espresso grinds. Vane pumps are considered to be differential-pressure pumps, meaning they can pressurize a fluid entering the pump suction at higher than atmospheric pressure, as might be the case for an espresso machine that is hard-piped to the water supply. Home espresso machines typically use cheaper piston pumps designed to draw water up from built-in tanks.

Automakers use vane pumps to pressurize the low-viscosity hydraulic fluid found in power-steering systems, for which the original Vickers pump was developed. They are used both as fixed- and variable-output units in automatic transmissions. Sliding-vane pumps are best suited to low-viscosity fluids that are free of particulates. External-vane pumps are sometimes deployed to handle fluids containing solids.

Sliding-vane pumps are regularly used in refineries, terminals, etc. for pumping oils, solvents, paints, and coatings, etc. Rotary-vane technology is applied to hand-cranked pumps for manual transfer and similar operations. In recent years, micro-hydraulic systems for use in personal-assist devices have brought about the need for miniature rotary-vane pumps.

Flexible-vane pumps are heavily employed for food, beverage, and pharmaceutical services as their low-shear designs allow them to move cosmetics and similar creams without affecting their qualities or pump fluids with solids (such as yogurt) without damage. The low-shear design is also applied for marine bilge pumping and water-based glue making, for example. Flexible-vane pumps produce only low to moderate pressures, and material viscosity has a role in just how high of a pressure can be attained.

Flexible-vane pumps have very good self-priming characteristics and can be used for tank stripping and similar operations without requiring valves or hand priming. They are reversible as well, making them handy for clearing intake lines of high-viscosity products. Flexible-vane pumps offer a relatively low-cost solution for pumping solids and shear-sensitive products over other low-shear designs such as rotary-lobe pumps.

Housings can be made in stainless steel for sanitary service or bronze for marine service but ductile iron is used where possible because of its self-lubricating characteristics. The pumps are available both as close-coupled and as sealless, magnetically-coupled units. Vane pumps fall about midway between economical gear pumps and expensive piston pumps.

Finally, while rotary, positive-displacement pumps are capable of pumping water, their primary application is for oils and viscous liquids because of the need to keep rubbing surfaces lubricated and the difficulty in sealing very thin fluids. For most applications where water is the media, the centrifugal, or dynamic-displacement, pump has been the clearer choice. Vane pumps work well with low-viscosity fluids and are used to pump water to moderate pressures in several specific applications as noted here.
