Rubber Pump Flex

Rubber Pump Flex's are primarily used to absorb noise and vibration between rotating equipment such as pumps or chillers and pipework. Their high flexibility also makes them suitable for compensating small installation misalignments. Rubber Pump Flex's can be used just like a metal expansion joint to compensate for axial, lateral or angular movement. As any other unrestrained expansion joint, rubber bellows will extend under pressure. Their pressure thrust however varies with length as the shape of the bellows change. However the forces involved are just as large.

The pressure thrust is calculated by multiplying the cross sectional area, times the maximum pressure. To prevent the bellows from extending, the pipework needs to be anchored. Typical applications are taking up thermal expansion in plastic pipework or noise isolation in small diameter pipework at low pressures. Fabricated Products bellows are thin walled and therefore extremely flexible, ensuring the highest degree of noise and vibration isolation.
