BLDC motor - accurate and high performance pumping

Categories: Latest NewsRelease time: 2016-10-26 18:23:00

    There is a wide range of applications requiring the targeted dosing of small volumes of liquid. High-tech solutions are called for if the application also requires a long service life and a seal-less pump design. Typical areas of application are the transfer of crystallizing, air-sensitive or outgassing media, fuel cell technology, the delivery of urea solution (AdBlue) to remove NOx from diesel engine exhaust gas, or dialysis and analysis technologies. The hermetically sealed pump head is driven by means of a powerful rare earth magnetic coupling, which prevents leaks on the drive end. In combination with the materials available, such as nickel-based carbides, stainless steels, ceramics based on aluminum, zirconium oxide or silicon carbide, and plastics such as PTFE, PEEK and FKM, the pumps can be adapted to various media, including corrosive substances. The pump, only 22 mm in diameter and 69 mm long, and weighing around 100g, is designed for 24 V operating voltage and can transfer 4.8 to 72 ml/min at up to 5 bar delivery pressure. Thanks to the annular gear design, the pumpable viscosity range is between 0.3 and 100 mPas, with a pulsation of around 6% and a differential pressure range of 0 to 5 bar. The no-valve annular gear principle guarantees minimal shear forces during pumping.
