Leading Rotary Vane Vacuum Pump Manufacturers

In its most basic form, a rotary vane vacuum pump is a pump technology that allows air to be compressed inside the pump chamber to create suction. This suction removes air molecules from a vessel or area. Rotary vane vacuum pumps operate based on the positive displacement pumping theory. They are designed with a rotor positioned inside a cylindrical housing or stator. Due to centrifugal force, blades positioned inside the rotor rotate in and out while adhering to the interior surface of the housing. Read More…

Rotary Vane Vacuum Pumps In many settings, rotary vane vacuum pumps may be used for vacuum generation. Rotary vane vacuum pumps feature a round enclosure, a rotary with vanes set within the enclosure and tubes for inlet and exhaust purposes. The inlet is connected to the area from which the pump removes atmosphere, and the outlet can lead to additional pumps or to an exhaust port.

Rotary Vane Vacuum Pump Interior

Design of Rotary Vane Vacuum Pump

Rotary vane vacuum pumps function using positive displacement. This means they create a vacuum and continuously evacuate chambers without needing to expand indefinitely by cutting off, exhausting, and re-expanding one of their sections. Positive displacement rotary vane pumps can also be built as dry or oil-sealed pumps. Dry pumps don't use any liquid to function.

Dry pumps rely on internal dimensional accuracy to create a vacuum, while wet pumps use fluid to form a seal. Oil-sealed pumps are wet pumps that specifically use oil to form a seal. Furthermore, a direct drive is used to construct many rotary vane vacuum pumps. Each rotary vane vacuum pump is constructed utilizing the same fundamental parts.

Depending on the design, size, or model, there will be modifications to the components. However, the below parts are typical of oil-lubricated and dry-running pumps.

Rotor: The pump’s rotor is usually wound with copper. The rotor rotates in this electrical engine and needs energy. The spiral layout's stationary element is called the stator. It encircles the internal surfaces of the motor housing and carries electrical current.

Oil Lubrication Rotary Vane Vacuum Pump

Vanes and Blades: The vanes are large blades affixed to a revolving axis or wheel. The vanes form a seal with the wall of the pumping chamber to stop fluid from flowing back across the pump.

Oil Sump: The oil sump stores the engine oil needed for sealing. An oil pump will send oil out of the sump, through the oil filter, and into the engine block's oil channels. The sealing points are then used to restore the oil to the oil sump.

Suction Flange: A suction tube is attached to a hydraulic tank using suction flanges. They create a seal to stop fluid leaks and pollution from getting into the tank. The suction element is also made possible via flanges without draining the tank.

Cylindrical Housing: The housing covering the pump’s exterior is usually made of aluminum die-casting. The compressor is housed inside.

Motor: A device that transforms electrical energy (AC or DC) into mechanical energy is an electric motor. The motor's magnetic field and the electric current flowing through a wire winding interact to produce the torque applied to the motor shaft.

Float Valve: A float detects changes in elevation on an oil-free surface and reacts by opening or closing a valve.

Applications of Rotary Vane Vacuum Pumps

Oil-Lubricated Rotary Vane Vacuum Pump Applications

  • These pumps are used in chemical and pharmaceutical processes, including degassing, crystallization, drying, distillation, evaporation, supercooling, fractionation, impregnation, vacuum coating (sublimation), and vacuum filtering.
  • Centralized vacuum systems are used in the food & beverage packaging sector in bottling and filling machinery.
  • Examples of industrial applications include vacuum hold-down, dust extraction systems, drying systems, and industrial furnaces.
  • Oil-lubricated vane pumps are used in pneumatic transport

Dry Running Rotary Vane Vacuum Pump Applications

  • Aeration in environmental engineering.
  • Industrial applications include picking and placing and lifting and holding.
  • Machines used in the packaging sector.
  • Dry-running rotary vane vacuum pumps may be used in post-press and printing presses in the printing business.
  • Industry of woodworking - vacuum hold down.

Advantages of Rotary Vacuum Pumps

One of the most common vacuum pump is the rotary vane vacuum pump. In actuality, most vacuum pumps use rotating vanes, paddles, blades, or impellers to move shuttle gas into and out of an enclosure. Therefore, any vacuum pump using any of these parts is a rotary vacuum pump.

Choosing the Right Rotary Vane Vacuum Pump Supplier

To make sure you have the most productive outcome when purchasing a rotary vane vacuum pump from a rotary vane vacuum pump supplier, it is important to compare at least 4 suppliers using our rotary vane vacuum pump directory. Each rotary vane vacuum pump supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the supplier for more information or request a quote. Review each rotary vane vacuum pump company website using our patented website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple rotary vane vacuum pump companies with the same form.
