Description

This type of magnetic drive pump is constructed of PP or PVDF, all fasteners are stainless steel. The pump impeller is designed to provide the max. flow rate and pressure for water type liquids. The only moving part inside the pump is the impeller magnet assembly and the bushing which rotates on the porcelain shaft. Not designed to run dry for more than a few seconds.

How Magnetic Drive Pumps Work

Magnetically driven pumps transfer power using a drive magnet which is fixed to the motor shaft, which rotates an internal magnet attached to the impeller via the magnetic field which exists between the two magnets. This means they are sealless.

Applications

Magnetic drive pumps should be used in situations where you really don’t want any leaks such as corrosive liquids and toxic liquids. The fact that they are manufactured from non metallic wetted parts also makes them very suitable for corrosive liquids.

Magnetic drive pumps are good in high temperature applications as there is no chance of seal leakage and the magnetic couple helps accommodate thermal movement. While low temperature and cryogenic applications are suitable for mag drive pumps as no heat is transferred from the motor into the pumped liquid.

Key Features

  • 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.
