PUMPS & FILTRATION
Why choose a magnetic drive pump?
So why would you want to
choose a magnetic drive
pump? They are a suitable
pump if the application
in question requires the
complete containment of the
process fluid being pumped.
For a magnetic drive pump,
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
