How does a magnetic impeller work?

In a magnetic drive pump, the wet end and motor are two separate contained parts, connected by only a motor bracket. 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.

What is a magnetic water pump?

A magnetic drive pump uses a balanced magnetic field to create the rotation of the fluid impeller. Unlike a traditional centrifugal pump which has a direct drive connection between impeller and motor, a mag-drive pump eliminates the direct drive mechanism and replaces it with a magnetic field.

What is sealless magnetic drive pumps?

What is a sealless magnetic drive pump? 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.

Do mag drive pumps have seals?

But since magnetic drive pumps contain no seals, and therefore no need for replacements, much less maintenance is required for seal-less magnetic drive pumps.

What does an impeller do?

An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid.

Are mag drive pumps self priming?

Sethco® magnetic drive self-priming pumps are precision designed to meet the demands of a wide range of OEM, chemical and industrial applications. These pumps can be used for highly corrosive or mild chemicals, acids or solvents.

Are magnetic drive pumps self priming?

Do mag-drive pumps have seals?

What do you mean by magnetic coupling?

A magnetic coupling is a coupling that transfers torque from one shaft to another, but using a magnetic field rather than a physical mechanical connection. Magnetic shaft couplings preclude the use of shaft seals, which eventually wear out and fail from the sliding of two surfaces against each another.

What would cause a pump to Cavitate?

Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). As the liquid passes from the suction side of the impeller to the delivery side, the bubbles implode.

How does a magnetic drive pump work in a pump?

Magnetic Drive Pump? “ Magnetic Drive ” refers to the coupling between the wet end of the pump and the motor. In direct drive pumps, the impeller of the pump is attached to the shaft of the motor, and this design depends on the shaft seal to contain the chemical. In a magnetic drive pump, the wet end and motor are two separate contained parts,

What kind of pump is a centrifugal pump?

Centrifugal Pump is a stand-alone pump with two different types of a unit a bare pump and an Electric Motor to run, mounted with a Coupling on a Base Frame.

What can a pneumatic barrel pump be used for?

Pneumatic Barrel Pumps are operated by a mean of Compressed air which is passed through the air Motor to rotate the Shaft and Impeller in the Pump Tube. These Pumps are widely used in Industries for transfer of any Liquids which are Highly Flammable Liquids and Chemicals like Vaseline, Paints, and Grease.

Which is the best brand of sealless pump?

Numatic Pumps is the brand with the greatest technical expertise in Manufacturing Industrial Pumps Mainly Magnetic Coupled Centrifugal Pump which is Sealless Pump. The other Range of Pumps is PP Pumps, PVDF Pumps, PTFE Pumps and PFA Pumps. Which are also called Plastic Pumps or Chemical Pumps or Acid Pumps.
