March May magnetics

hy would you want to choose a magnetic drive pump? Magnetic drive pumps are suitable if the
application in question requires the complete containment of the process fluid being pumped. Instead of having a shaft that passes through the body of the pump, which requires a dynamic seal, the pump has one assembly of magnets attached to the shaft of the motor and a second assembly of magnets attached to the impeller inside the pump body. When the motor rotates, the magnetic field generated between the two magnets means that the impeller turns in the pump body. The liquid to be pumped is therefore contained within the hermetically sealed pump housing without the risk of any leaks from the shaft seal.
Advantages of magnet drive pumps:
Very low risk of fluid emissions from the pump Low maintenance seal less design No pump to motor alignment problems Quick wet end and pump head service replacement

The UK manufacturing facility includes
a range of the newest injection moulding machines and manufacturing of all plastic parts for its pumps is carried out in-house to ensure the highest standards of quality are achieved and maintained. March May recently invested in a Hurco 3D
machining centre to further support growth in new product design whilst also being an additional asset to the already well-equipped factory. There is also an in-house well- equipped research and pump test laboratory that allows the development, prototyping and test of bespoke products.
