What is a magnetic drive?
“Magnetic Drive” refers to the coupling between the wet end of the pump and the motor. At the end of the motor shaft, a drive magnet is attached, and as the drive magnet rotates around the rear housing, the impeller, which is fixed upon another magnet, spins in synchronization.
What are magnetic drive pumps used for?
Magnetic drive pumps are typically used where leakage of the pumped liquid poses a great risk such as with aggressive or risky liquids, exotic materials, acids, alkalis, corrosives, pollutants and toxics. They are also used for ultra-pure liquids and hard-to-seal liquids.
How does a magnetic sealless pump work?
The principle of operation is very simple. The magnets in the outer and inner magnet rings are attracted to each other, so as the electric motor rotates, the outer ring and the inner ring rotate at the same speed, thus rotating the impeller and causing liquid to be pumped.
What is magnetic coupling pump?
A magnetic coupling can be used to transfer power to centrifugal pumps. It consists of a primary part which is rigidly connected to the motor shaft, and a secondary part which is arranged on a shaft (see Pump shaft) together with the impeller. They attract each other due to the magnetic flux. …
How does a magnetic drive work?
In a magnetic drive pump, the impeller and motor have magnets attached to them. Permanent magnets are attached to the pump’s drive assembly. The drive magnet, the magnet responsible for driving the inner rotor, is attached on a second shaft operated by the motor. When the motor turns on, it spins its magnet.
How do you prime a magnetic drive pump?
To prime, pour liquid into the outlet tubing or piping and allow it to fill the pumping chamber. The pump will normally prime with less effort when a foot valve is installed at the end of the suction line; this will also eliminate the need to reprime each time the pump is turned off.
How do electromagnetic pumps work?
An electromagnetic pump is a pump that moves liquid metal, molten salt, brine, or other electrically conductive liquid using electromagnetism. A magnetic field is set at right angles to the direction the liquid moves in, and a current is passed through it. This causes an electromagnetic force that moves the liquid.
What is sealless magnetic drive pumps?
A sealless mag drive pump is a conventional centrifugal pump without the dynamic seal that would normally be used to seal the pump shaft. This dynamic seal is replaced by a static containment shell to form a completely sealed liquid end or pressure boundary.
What is 2 coil magnetic coupling?
The fraction of magnetic flux produced by the current in one coil that links with the other coil is called the coefficient of coupling between the two coils. It is denoted by (k). k=1, when the flux produced by one coil, completely links with the other coil and is called magnetically tightly coupled.
How does a magnetic coupling work?
In the simplest terms, magnetic couplings work using the fundamental concept that opposite magnetic poles attract. The attraction of the magnets transmits torque from one magnetized hub to another (from the driving member of the coupling to the driven member). Torque describes the force that rotates an object.
Are magnetic drive pumps self priming?
Klaus Union’s sealless self-priming magnetic drive pumps eliminate the mechanical shaft seal of a conventional pump and provide a more reliable, safer and more cost effective solution – self-priming and 100 % emission free. …
