Micro gear pumps for high pressures, low flows
The new GAF Series of electromagnetic gear pumps from Micropump are suitable for fluids transfer applications which require chemically resistant, leak-free pumps providing high differential pressures at low flows, in a compact, yet robust package.
Available from Michael Smith Engineers, these pumps provide extended differential pressures up to 250psi (17bar) with precise, smooth pulseless flows up to 550ml/min. They include other features, such as wear compensation for near zero slip and extended life, along with the all-important magnetic drive, which eliminates the need for leak-prone shaft seals.
The suction shoe design of the pump compensates for wear and makes them particularly suitable for continuous duty processes, whilst ensuring optimum efficiency at higher pressures. Precision pumping elements provide fluid delivery with continuous positive displacement which also reduces system complexity by eliminating system pressure "spikes' and the need for additional devices such as pulse dampeners.
Micropump's GAF Series ability to deliver uniform, pulseless flows over a wide range of pressures and temperatures makes them suitable for fuel cell applications, for example for R&D, test and development situations, through to high-volume production applications.
