Single-Sphere Molded Rubber Expansion Joints

Reduce noise and vibration with Single-Sphere Molded Rubber Expansion Joints (Series AMS), suitable for suction and delivery applications. These molded rubber expansion joints can absorb motion and reduce stress. They come with ANSI Class #150 drilled flanges and can be customized with ANSI Class #300 and DIN-rated flanges.

FEATURES

Applicable for suction and delivery (discharge).
Provides sound and vibration isolation.
Gaskets and packing are not required.
Floating flanges allow for easy installation.
Prevents piping system and equipment breakdown by absorbing elongation and contraction caused by temperature variances.
Absorbs water pulsation and minimizes water hammering.

APPLICATIONS

Pumps & air compressors in air conditioning system & sanitary equipment.
Refrigeration systems and blowers in industrial plant equipment.
Feed-water and drainage equipment in marine piping systems.
Applicable for use in power generation and chemical plants.
Marine applications
