Magnetic Driven Pumps
Centrifugal pumps that use a sealed barrier (usually
plastic) to isolate the pumps impeller from the motor. Within the impeller are
magnets that are used to transfer the rotating force from motor drive magnets.
Considerations unique to magnetic driven pumps
- the magnets will attract iron and
steel particles
- the connection between pump and motor
is not direct and may become lost if loads or starting torque is high.
- the pump has close clearances within
-- NOT desirable when handling abrasive solutions or "electroless plating
solutions."
- the pump does not have a drive shaft
that requires packing or a mechanical seal
"Mag drive pumps" a popular choice because
they are considered "seal-less" and typically stop running before any leakage
would occur. This is very desirable when using corrosive chemicals. For may
applications with flow rates under 60 GPM, that require a thermoplastic pump,
they generally
cost less and are easier to maintain than pumps with mechanical seals.
Mag drive pumps are available in large sizes that cover flow rates up to
3000 GPM.
Thermoplastic Mag drive pump are usually constructed of
polypropylene or Ryton however often could be constructed of PVDF (Kynar). In the larger sizes, they are
metal with a fluoropolymer (ETFE) lining. The fluid would not come
in contact with the metal - it is there for additional strength.
Metallic Mag drive pumps are used primarily
for corrosive chemicals when seal failures
cannot be tolerated. Higher
in initial cost to purchase but often offer
a payback in long term maintenance
costs. Go to this type of pump.
