ST/ST Pump Flexible


ST/ST Pump Flexible EMFLEX single articulated expansion joints

EMFLEX single articulated expansion joints (also known as single ‘untied’ or ‘tied’ flexible connectors) are used to absorb vibration in pumped systems and misalignment in pipework systems. They are usually installed at the pump suction and discharge connections. The tie rods prevent elongation due to the internal pressure thrust.

The units are not intended to absorb vibration and misalignment simultaneously. Axial thrust must not be applied to these units, for example when pipework is mounted vertically from the unit. In this situation the pipework should be supported using spring supports.
