Targeting company standards and special ambient conditions
Pumps and compressors make up about one third of energy consumption in industry. Consequently the market is big with the portfolio ranging from miniature laboratory pumps to large-scale plants for petrochemistry.
An essential function of the coupling is the ability to compensate for displacements in the drive train. That is why double-cardanic couplings are often used. Apart from that radial assembly and disassembly without dismounting adjacent drive components is a vital demand from the part of process and petrochemistry.
Torsional flexibility and damping of vibrations is required to increase the service life of the overall pump drive. Another specification is conformity with industry standards (API, ATEX etc.) and company standards.
We offer an extraordinarily wide range of couplings up to a maximum of 280,000 Nm to the manufacturers and users of pumps and compressors. Some series were specifically developed for this industry. Here the focus is on the users’ request to increase the pump’s service life, availability and efficiency by selecting the optimum coupling.
Being a listed and approved supplier of large companies in chemical and oil industry like Saudi Aramco and PDO, we are working closely with the customers developing special solutions that are tested in our test field at our headquarters in Rheine. The couplings comply with the API standards. The product portfolio includes both series for potentially explosive atmospheres and couplings with integrated overload protection or electronic torque monitoring as well as magnetic couplings for contactless torque transmission.
