How a Vain Pump Works | Becker Vane Pump

A vain pump like Becker’s Vane pumps, are often called positive displacement pumps because they work using positive displacement. This means it is made up of a series of vanes mounted within a rotor to provide circulation within the main cavity. Making it possible to force air through a pipe, duct or process at varying rates based on the application. Or even, to pull the air into or through a process when a vacuum is required.

When a vein pump or Becker rotary van pump, is in operation, the vanes slide in and out. Creating a seal around the cavity or chamber which allows a series of smaller chambers to form within the larger chamber. Inside each chamber, air is captured and compressed, forcing it through the system, which is caused by the increasing or decreasing sizes of the chambers between the vanes, while rotating.

The rotor supports the continuous flow of air in a uniform manner during the process and does this without any of the “Pulsations” that most other technologies of pump create.

A vain pump, vein pump, or vane pump can be used for either vacuum or pressure, and sometimes both!

What Kinds of Applications are vain pumps Used In?

  • Pick and place
  • Vacuum infusion of composites
  • Paper and Plastic Packaging
  • Food Packaging and Processing
  • Printing and Paper Converting
  • Medical/Surgical Vacuum
  • Vacuum Hold Down for CNC routers
  • Environmental Applications
  • Lots more!!!

Rotary Vain Pumps often power laboratory vacuum systems and aircraft vacuum systems. They can also be used in medical applications and to evacuate and recover refrigerants from air conditioning systems.

Small rotary vein pumps, vain pumps, or vane pumps, can be used for drink dispensers, medical dispensing pumps, and water pumps on marine engines.

The Different Types of Rotary Vane Vacuum Pumps

  • Oil-Less Vacuum Pumps
  • Dry Vacuum Pumps

What’s the difference between dry vacuum pumps and oil-less vacuum pumps?

Rotary vane pump technology is an older technology that has been used in commercial and laboratory-grade vacuum pumps for over 50 years. The oil inside the pump seals, cools, and lubricates the pump simultaneously which makes these pumps a very efficient solution for those on a budget.

Oil-free vacuum pumps are increasingly becoming more sought out in the industry as the focus on cleaner, pharmaceutical-grade extracts grows. Since there is no oil used in the pump, you don’t have to worry about product contamination or even premature wear and tear of your equipment.

Becker Rotary Vane Pumps, Your #1 Vain Pump

Becker Pumps offers vane pumps that suit a variety of needs. Our rotary vane pumps feature a variable speed controller that is intelligent. These pumps are suited for vacuum or pressure vein pump applications.

Additionally, our famous vane pumps offer:

  • Extended vain life
  • 100% oil-less operation
  • 2:1 flow ratio
  • Integrated or external inlet filters

The maintenance of our rotary vane pumps are relatively simple. Many of these pumps are direct-drive pumps with no gears or transmissions to reduce operating speeds. Periodic inspection of the vanes for wear and vane damage is needed for optimum performance. A shaft seal between the pump and motor might need periodic maintenance but can be eliminated in some cases by the use of a magnetic coupling that uses a sealed magnet inside the pump case driven by a matched magnet on the motor shaft.

The advantages of a rotary vane pump include good wear characteristics of the vanes if the pumped material is not abrasive and a low parts count because a transmission or gear reduction might not be required. This type of pump also has good performance with gases and low vibration because of its low operating speed.

All of our pumps are quiet and compact, making them the preferred option for many users. They also require minimal maintenance.
