| The above performance is for rubber elastomers -- The maximum flow will
be reduced by about 20% when using Teflon Diaphragms. This is due to a shorter pump
stroke length. Performance is a balance of the incoming air supply pressure and quantity (SCFM) verses the piping system resistance. As example -- 80 PSI air supply - would pump 3 GPM with 20 PSI and use 7 SCFM. If the back pressure of the system were reduced, the flow would be increased. The use of a solenoid controller can provide for a fixed flow rate. |
