A mounting portion (38) extends out- ward from the center of the face of the planar portion (40) on the 66 72 48 first side of the diaphragm (18). For metering pump applications pumping harsh fluids, the diaphragm (18) is typically made from -4 a fiuoropolymer and in particular may be made from polytetraflu- _ = = oroethylene (PTFE). 56 62 A 1. 64 A 11 - N ei in 71' 0 20 --.... 1-1 © ei II 10 ,P)1 1 il lial ► 24 C
