ABP Series

These shock absorbers are designed to limit excessive pressure variations caused by pump shut-offs or valve closings. ASME code fabrication, these vessels come with a heavy-duty bladder. It will eliminate any possible damage and destructive force that can cause wave shocks when the rate of flow changes abruptly. This water hammer may occur in a closed conduit flowing full when there is either a retardation or acceleration of the flow, such as with the change in opening of a valve in the line. For selection and sizing, contact our office or your local Calefactio representative.
