* = Recommended flow is half of the max flow, i.e. recommended flow for a T120 is 60 l/min
** = The value is based on pumps with EPDM diaphragms. Pumps with PTFE diaphragms produce approx. 15% less volume
*** = This is the max value with stainless steel valve balls, other valve ball materials may reduce the suction.
