* = Recommended flow is half of the max flow, i.e. recommended flow for a T100 is 50 l/min

** = The value is based on pumps with EPDM diaphragms. Pumps with PTFE diaphragms produce approx. 15% less volume

*** = This is maxed value with stainless steel valve balls, other valve ball materials may reduce the suction.
