Abstract
A three-piece combination spacer and shim assembly is provided for an air operated diaphragm pump. The spacer/shim assembly is disposed between adjacent parts of the manifold assemblies of the pumps to alleviate dimensional stack up and misalignment problems associated with the manifold assemblies of air operated diaphragm pumps. The assemblies provide a seal between the spacer component and the adjoining flanges of the manifold components.
