Catalog excerpts

Circular pumps BFP ATEX-2GD Drives and hydraulic aggregates with bypass filter and/or cooler are also used in explosive areas in machine construction or raw material production. The advantage of these circuits is that they create stable and therefore more predictable operating conditions for both the filtration and cooling. Circulating oil in these circuits requires efficient and preferably silent circulation pumps which provide a constant flow rate at moderate pressures. Internal gear pumps have proved especially useful for these applications. They offer compact integration, are relatively insusceptible to particle contamination and have a long life. ATEX area of application: up to zone 1 and zone 21 T4 Low noise emission High vol. efficiency Good suction performance Gerotor principle Not susceptible to contamination BFP ATEX 2GD series gerotor motor/pump units are suitable for use in explosive zones 1 (gas) and 21 (dust) and temperature class 4.

Why gerotor? Numerous applications in hydraulic and lubrication systems just require the circulation of the fluid. In such cases low noise emissions and low pressure ripples are more important than highly efficient transmission of energy. The gerotor is the ideal principle for such applications. The displacement mechanism consists of the inner and the outer rotor. The number of teeth of the inner rotor is always one less than the outer rotor. The rotation of the gerotor generates chambers of changing volumes between the inner and outer rotor. The variation follow a sinus curve, resulting in...

BFP ATEX-2GD Pump selection information: When selecting the pump model, choose the motor output according to the oil viscosity to be used. Motor output information refers to the maximum oil viscosity at maximum operating pressure. The BFP 8 to BFP 40 are also available as a special version with a 6 bar internal bypass valve for protection. This does not change the dimensions. Installation information: The pump head of all pumps can be mounted turned in 90° increments to align with the line routing. Please note the offset from the centre of the motor. The connection threads are manufactured...
