Mobile machines mainly use I.C.-engines as a drive. On hydrostatic drives hydraulic pumps are directly connected, while the compressor unit is driven directly with mobile compressors. Both units are connected via a flange coupling. That is why it has to meet a large number of demands, while primarily it has to transmit the power reliably to ensure that the machine is in a position to perform the work as required.
The material combination between hub from steel and flange toothing from carbon fibre-reinfored nylon allows for a longer, maintenance-free permanent operation thanks to further optimised coefficients of friction in the spline combination.
The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents, etc. make polyamide an ideal material for components stressed by sliding, particularly for the coupling production.
For connecting hydraulic pumps to the diesel engine KTR supplies mounting flanges according to SAE connection dimensions sizes SAE 6 to SAE 1. These flanges are made of steel and EN-GJL--250 (GG25) for hydraulic pumps with flange connections according to SAE-A, -B, -C, -D and -E as types with 2 and 4 holes.
Pump connection housings made of EN-GJL-250 (GG25) to be mounted directly to the back plate of the engine.
