How does a mag drive pump work?

The drive magnet is attached to the shaft operated by the motor. As the motor turns on, it spins the drive magnet which in turn spins the magnet attached to the impeller. The rotation of the impeller produces the power that drives the liquid through the pump.

Where are magnetically coupled pumps used?

Due to their seal-less design meaning they are not prone to leaks, magnetic drive pumps are very popular for the pumping of flammable, toxic and hazardous chemicals, acids and other potentially dangerous fluids that do not contain abrasives.

Can a magnetic drive pump handle solids?

No! The presence of solids can stick to the magnets and interfere with the operation of the pump.

Can a mag drive pump lose its magnetism?

Under extremely high temperatures or excessive torque the magnets may decouple meaning that the pump shaft can slip causing stoppages and inefficiencies.

Eliminate Leaks With Our Magnetically Coupled Vane Pumps

Are you sick of the mechanical seals on your pump wearing and causing leaks? Magnetic drive pumps may be your answer! The key design feature of magnetic drive pumps is that they do not have a mechanical seal, and instead use magnets to couple the pump head to the motor. This eliminates the chances of leakages caused by the mechanical seal wearing over time, making it a cleaner solution, ideal for pumping chemicals and aggressive fluids that can be potentially dangerous if leaked. Magnetically coupled vane pumps in particular tend to be used for flammable environments where medium viscosity oils, lubricants and fuels are pumped at high pressures, as well as low viscosity fuels such as alcohol and petroleum thanks to no metal to metal contact inside the pump. If you have an application that you think would benefit from a magnetic drive vane pump over a mechanical seal solution, then contact our pump experts for advice selecting the mag drive pump for your application.

FAQs

Rather than having a mechanical seal to prevent liquid escaping from between the motor and pump shaft, magnetically coupled pumps use two magnets. The absence of mechanical seals that are prone to wear reduce the chance of leaking and maintenance.
