Mag-Drive Gear Pumps
Magnetically driven gear pumps are designed to:
- eliminate dynamic seal leaks
- increase maximum system pressure
- minimize the risk of contamination
Most Micropumps use external gear pump technology, although some use centrifugal pumps.
External Gear Mag Drive Pumps offer low flow rate sensitivity to differential pressure, and very low pulsation.
- External gear suction shoe style mag drive pump feature a pressure-loaded design that allows the pump to self-compensate for wear, maintaining stable performance. Suction shoe pumps maintain high-volumetric efficiency, even at elevated pressures, and offer long life and near-zero slip for accurate metering.
Magnetic Drives
Micropump offers magnetic drives in standard and custom designs, or electromagnetic.
Magnetic drives feature magnetic couplings consisting of a drive magnet attached to the motor shaft and a driven magnet connected to the driving gear. The driven magnet is a wetted component and is totally encapsulated within the pump head. The drive magnet turns the driven magnet and gears without physical contact, so no dynamic seals are required. The result is smooth flow, self-priming, compact size, and a direct relationship between pump rotational speed and flow. Mag-drive pumps can be driven by AC motors, DC brush motors, DC brushless and stepper motors.
Electromagnetic drives are designed with a stator winding instead of a magnet hub assembly to create the magnetic field. This design further reduces the size of the drive, and decoupling is eliminated. Because the drive doesn’t have any moving parts, reliability is improved as well.
