RVS expansion joint Pumpflex | Pumpflex

with tie rods

Suitable for: In pipelines and installations where one wants to reduce vibrations and forces. Pumps, compressors, motors, burners, etc. Building technology, industrial plants. Heating, cooling, ventilation and heat recovery plants. Gas, water and wastewater treatment plants.

• These PN-16 pumpflex expansion joints ensure maximum attenuation of noise and vibration via the flexible multi-wall bellows and vibration damping seats in the tie rods.
• At the same time, they can still withstand high temperatures, making them a great alternative to rubber expansion joints.
• The build length is also adapted to this which increases interchangeability.
• Unlike a rubber expansion joint, it resists high temperatures, UV radiation, aging and a lot of aggressive media.
• With rotatable steel flanges that simplify assembly. Also available with fixed and/or stainless steel flanges, even with different bore.
• Greatly increases the operational reliability of installations and appliances.
• Significantly longer service life than rubber expansion joints.
• No pressure reaction forces on pump or piping by use of tie rods.
• Movements in the bellows calculated at EJMA standard, not combined and calculated at 7000 cycles.
