BELLOWS PUMP CONNECTORS

All bellows differ from Stainless Steel Hose in the corrugation configurations. Bellows are deeper and wider, and they are made of heavier material, to handle the pressures without braid. A very common location for our 2 ply Bellows is at the pumps. The face to face dimension is equal to the length of most Single Sphere Rubber Molded Expansion Joints. This product should be used when a combination of short length with greater movement capabilities along with the other benefits of stainless steel (high temperature and pressure) are required. If the equipment is solidly mounted, and there is an anchor somewhere in the line on the other side of the bellows, they will accept 1” (25mm) of compression and 3/8” (9mm) of elongation. Transverse movement varies between 1/8” (3mm) and 3/8” (9mm), depending on diameter.

If no anchors are provided, the joint will always remain in the full open position against the rubber isolated control rods and only serve to reduce transverse misalignment.
