1 SITEX escription The SITEX couplings are esigne or optimizing the connections between reciprocating engines an riven equipment such as pumps, compressors, generators, etc. SITEX couplings consist o a steel hub an iberglass reinorce polyamie lange which oers both mechanical strength an imensional stability in a variety o temperature ranges. The special teeth allow SITEX couplings to compensate or small misalignments thus avoiing wear. The steel-polyamie coupling allows maintenance ree continuous operation. pprove accoring to E stanar TEX 94/9/E. ain characteristics an avantages inimum imensions: The entire coupling is usually installe insie an engine housing, minimizing the axial imensions thus reucing the tools require or installation. xial misalignments: The hub toothing can move reely axially insie the Polyamie lange avoiing axial orces which may arise on the pump shat. Heat stability: The special iberglass reinorce Polyamie lange is esigne to operate in internal combustion engine environments without air cooling an up to 140. aintenance ree: The SITEX joints are maintenance an lubrication ree. Quick assembling: lin assembly makes installation o the SITEX quick an easy. ngular misalignments: The special teeth allow angular misalignment correction, protecting the bearings against angular orces. Stiness: The stiness o the SITEX coupling allow or torsionally vibration-ree operation. The SITEX couplings are use in connections between the lywheels o the internal combustion engines an: hyro-pumps, rotating pistons, an compressor blaes. 34 irect rives
