40mm Pump Bellow Untied | National Pumps & Boilers

The 40MM Pump Bellow Untied is a pump bellow fitting that absorbs vibration and movement between the pump and connected pipework. It protects the system from stress caused by thermal expansion and pump operation. Key benefits: • Absorbs vibration from pump operation to protect surrounding pipework • Compensates for thermal expansion and contraction in heating systems • Reduces noise transmitted through pipes from running pumps • Flexible design prevents stress damage at rigid connection points • Durable construction for long service life in commercial systems An important fitting for commercial pump installations where vibration control and pipework protection are priorities.
