Magnetic Drive Pumps

AxFlow offers the largest choice of magnetic drive (mag drive) pumps available in the UK, including sealless centrifugal pumps, magnetically driven vane pumps, mag drive turbine pumps and mag drive gear pumps.

Mag drive pumps are a form of sealless pump: instead of using a dynamic shaft seal (such as a mechanical seal), power is transmitted via a magnetic coupling—helping to minimise leakage risk and improve containment in demanding duties.

HOW MAG DRIVE PUMPS WORK

Magnetically driven pumps transfer power using a drive magnet fixed to the motor shaft. This rotates an internal magnet connected to the impeller via the magnetic field between the two magnets. Because the motor shaft does not pass through the rear pump casing, the pump can operate without a dynamic seal, in other words it is sealless.

Advantages of mag drive pumps

Mag drive pumps are best suited to duties where containment & reliability matter most:

• Sealless pump design (no dynamic seal) helps minimise leakage risk
• Complete isolation of the pumped fluid.
• Containment of the liquid.
• Reduced heat transfer from the motor into the pump chamber.
• Motor overload protection

WHEN TO USE MAG DRIVE PUMPS

Mag drive pumps are commonly used when you really don’t want any leakage, such as with corrosive liquids and toxic liquids.

They are also well suited to temperature extremes:

• High temperature applications: there is no seal to leak, and the magnetic coupling helps accommodate thermal movement.

• Low temperature and cryogenic applications: suitable because no heat is transferred from the motor into the pumped liquid in the way that can occur with some alternative arrangements.

Mag drive pumps can also be manufactured with non-metallic wetted parts, which can make them especially suitable for corrosive chemical duties

 Key Features of magnetic drive pumps

Sealless Design: One of the most significant features of magnetic drive pumps is their sealless design. Traditional pumps use dynamic seals (e.g., mechanical seals) to prevent leakage of the pumped fluid. Mag drive pumps eliminate the need for these seals by using a magnetic coupling between the motor and the impeller.

Magnetic Coupling: Mag drive pumps employ a pair of magnets, one attached to the motor shaft and the other to the impeller shaft. These magnets are arranged in such a way that they create a magnetic field that couples the rotational motion of the motor to the impeller.

Corrosion Resistance: Mag drive pumps are often constructed from materials that are highly resistant to corrosion, such as plastic (e.g., polypropylene or PVDF) or corrosion-resistant metals (e.g., stainless steel or titanium).

Minimal Maintenance: With fewer moving parts and no seals to replace, mag drive pumps often require less maintenance compared to traditional pumps. This can result in lower operating costs and less downtime.
