Single Sphere Molded Rubber Expansion Joints (AMS Series)

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.
• DIN PN10/PN16 drilled flanges available upon request (See DIN Flange section for dimensions)

 

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
