Overview
CR and CRI pumps with oval flange connections come complete with threaded oval flanges, bolts and gaskets; these parts replace them or convert a FlexiClamp pump to another connection. Pick the pump and base type first, then the connection and elastomer.
CRI 1s, 1, 3 and 5 pumps with FlexiClamp need the tall base to take the 1 1/4 in ANSI flanges.
