A rotary vane pump is used to clean and transfer materials for industrial vacuum systems.

A rotary vane pump is a positive displacement pump that transports fluids and gasses with the help of vanes mounted to a rotor inside of a cylindrical housing. The pump consists of two chambers: one that expands and sucks in contents and another that collapses and releases them.
Benefits of Rotary Vane Pumps
- • Virtually pulsation-free
- • Compact
- • Strong vacuum
Parts of a Rotary Vane Pump
The stator is the cylindrical housing that encases the rotor The rotor moves with the help of a motor and rotates vanes that push outward against the stator due to centrifugal force. The vanes divide the working chamber into the suction chamber and discharge chamber. The inlet valve takes in gases and fluids, which are released through the outlet valve.
How a rotary vane pump works
The rotary vane pump rotates and compresses gases and fluids, which creates a vacuum that traps and transports the contents.
- When the rotor starts spinning, the vanes slide in and out to extend and turn against the inner wall of the stator.
- As the vanes rotate, the working chamber forms, sealed by the outlet valve to separate the chamber into suction and discharge sides.
- The gas and fluids enter with the first 180-degree rotation.
- The vanes compress with each rotation until the suction chamber reaches maximum capacity. The pressure on the outlet valve increases until it opens and releases the contents through the outlet port.
- The exhaust valves keep the dispelled contents from flowing back into the pump.
Activated carbon filters can help control corrosion on the pump.
Carbonator pump motors are electric motors that attach to the pump head of rotary vane and other hub-mounted pumps for smooth fluid transportation.
A carbonator motor works like any other electric motor. Electromagnets supply the power to the motor. The motor is made up of the following parts:
- • Battery or other power supply
- • Armature
- • Axel
- • Commutator
- • Brushes
- • Magnetic field
How a carbonator pump motor works:
- The pump is turned on, creating a closed circuit that provides the current of electricity.
- Electrical current flows from the battery to the armature connected to an axel. The wires wrapped around the metal armature create a magnetic field with north and south poles.
- The opposite charges attract, and the like charges repel, causing the magnetic field to rotate halfway.
- The axel on the armature is connected to the commutator. As the magnetic commutator rotates with the armature, it encounters the metal brushes. This changes the direction of the electrons and causes the magnetic field to complete the rotation.
- This electricity produces motion that powers the motor.
