Magnetic drive pumps are often selected when chemical leakage, seal failure, or hazardous fluid handling becomes difficult to manage with conventional sealed pumps.
For Australian plants, the pump itself is only one part of the decision. Local support, correct material selection, spare parts availability, and application experience all affect how well the pump performs over time.
Global Pumps supplies magnetic drive pumps for corrosive, aggressive, and hazardous chemical duties, with almost 50 years in the Australian market. We have worked across applications and projects of all sizes, from individual pump replacements through to custom-built pump systems designed around site-specific requirements.
Why choose a magnetic drive pump?
A magnetic drive pump is a type of centrifugal pump that uses an outer magnet connected to the motor and an inner magnet connected to the impeller. Torque passes through the containment shell magnetically, so the motor can drive the impeller without a shaft passing through the pump casing.
This is the key technical difference. Because there is no shaft penetration, the pump does not need a mechanical seal. The pumped fluid remains contained inside the wet end, which reduces one of the main leakage points found in conventional sealed centrifugal pumps.
For chemical duties, this design is useful because a common failure point is removed rather than upgraded. There are no seal faces to wear, no seal flush system to manage, and no seal elastomers exposed to repeated movement and friction.
What magnetic drive pumps offer
For suitable applications, magnetic drive pumps can provide:
-
Lower leakage risk on hazardous or corrosive fluids
-
No mechanical seal to replace
-
Long operating life with reduced routine maintenance
-
Easier coupling, with less complex pump-to-motor alignment
-
Options for solids handling, depending on the model selected
Selected models can handle solids up to 30% and particles up to 6 mm.
Why Techniflo magnetic drive pumps?
Techniflo magnetic drive centrifugal pumps conform to ANSI B73.1M, a recognised dimensional standard that helps simplify installation and like-for-like replacement.
In many cases, they can be used as direct bolt-in replacements for existing sealed pumps. This can help avoid changes to motor size, wire gauge, or breakers.
Their low net positive suction head (NPSH) requirements also make them suitable for systems where inlet pressure or liquid height is limited.
For hazardous areas, magnetic drive pumps can be supplied in ATEX or IECEx-approved configurations where required. We can confirm the right package based on your fluid, duty point, site classification, and operating conditions.
Why work with Global Pumps?
We support the full pump lifecycle.
Our speciality is custom-made pump systems built to suit the application, rather than forcing a standard pump into a difficult duty. We also stock spare parts locally and can assist with servicing and repairs, giving Australian operators support that may not be available with other pump products.
That local support matters when a pump is handling corrosive or hazardous chemicals. Fast access to spares, repair knowledge, and application advice can reduce downtime and help keep the system operating safely.
A practical option for chemical duties
Magnetic drive pumps are not the right fit for every application. Fluid properties, solids content, temperature, viscosity, suction conditions, and hazardous area requirements all need to be reviewed.
Where seal failures are recurring, however, a magnetic drive pump can be one of the best options available.
For Australian chemical applications, Global Pumps combines magnetic drive pump supply with local engineering support, spare parts, repairs, and custom-built pump system capability.
If you have a tough chemical duty and want to assess whether a magnetic drive pump is suitable, our team can work through the application requirements with you.
