Hydrostatic CouplingHYDROFLEX MA-S
HYDROFLEX MA-S – Torsionally flexible coupling for industrial applications
Machines like small excavators, forklifts, mini dumpers, asphalt machines, concrete pumps, agricultural machinery etc use hydrostatic drives from a combustion engine, directly connected with a hydrostatic pump via a coupling. The coupling conveys the required force from the engine to the pump and consequently ensures proper machine operation. The coupling must also be able to be installed and plugged into the smallest area under the pump installation flange of the engine, so that the hydraulic pump can be flange-mounted directly to the engine. Hydrostatic applications generally require a rigid coupling to operate hydraulic pumps and similar machines with low torque of inertia below the critical speeds, whereby possible damaging resonances from the machine’s operating speed range are removed. VULKAN has developed its HYDROFLEX coupling program for this application – also known as HYDROFLEX MA-S, a torsionally flexible coupling for direct connection between diesel engines and one or more hydraulic pumps.
