A high pressure water jet, when precisely directed against a surface, is a perfect tool for industrial maintenance operations, such as internal and external cleaning of different types of containers, equipment and surfaces and the cleaning of pipes, ducts, heat exchangers, ship sides and runways. The engine of a high pressure cleaning unit is usually connected to a plunger pump. It is for these applications that German company, Reich-Kupplungen, offers and ideal coupling solution.
The highly flexible Arcusaflex coupling is the ideal connector for an 180 kW diesel engine running at 1880 rpm connected to a 1000 bar high pressure pump. The different sizes of the Arcusaflex flange coupling series cover a torque range from 200 to 110000 Nm (corresponding to up to approx. 6500 kW at 1000 rpm). The element versions are available in different torsional stiffnesses and allow for adjustment to the most favorable torsional vibration situation. The flange connection dimensions of Arcusaflex couplings basically comply with the SAE J 620 or the DIN 6281 standard.
The optimized design of highly flexible Reich couplings takes into account both the excitations from the engine and from the pump, increasing the service life of all power transmission components, thus lowering the total cost of ownership. The respective torsional vibration calculations are performed as a service by Reich-Kupplungen for high pressure pumps, screw and piston compressors, and all combustion engine drives.
