Chemical gear pump TEF-MAG® 1500

The pumps of the MARCH TEF-MAG® series are magnetic-drive, externally toothed, rotary positive displacement pumps made of non-metallic materials, developed for operation with highly corrosive chemicals. Gear pumps produce an almost pulsation-free positive flow according to the displacement principle with high differential pressure. The pump casings of the TEF-MAG® series are machined from robust solid material and corrosion-resistant plastics such as PP, PVDF, PEEK, PVC or PE. The wetted shafts are also made of non-metallic technical ceramics such as SSiC or Al2O3, which represents the best possible chemical resistance. The gears are made of high-performance plastics with self-lubricating properties. The pumps of the TEF-MAG® series are therefore also able to pump low-viscosity liquids without problems. Power is transmitted from the drive to the pump without contact by strong NdFeB permanent magnets. As a result the pump works without any mechanical shaft seal, so that safe and leak-free pumping of corrosive, toxic and explosive liquids is ensured. Pumps for potentially explosive areas of Zones 1 and 2 can be supplied in corrosion-resistant and conductive plastics.
