37 MEDICATORS D40MZ2 Medicator The D40MZ2 replaces the D8RE2 high capacity medicator with an improved piston and 63% fewer replacement parts. Its 40 GPM flow rate handles the needs of large multihouse sites. The exterior sleeve regulates the injection rate from 1:50 to 1:500. • Flow range: 2.2 - 40 GPM • Adjustable ratio: 1:500 to 1:50 • Percentage Range: 0.2 to 2% • Pressure: 4.3 to 116 PSI • Size: 25-1/4” x 8-1/2” • 1-1/2” NPT inlet/outlet #D40MZ2..............................................................................40 GPM Medicator D40MZ2 Replacement Parts 1) #8MP039...................................................................Bell Housing Assembly 2) #PDI700................................................................Air Bleed Protective Cap 3) #MPDI184..........................................................................................Air Bleed 4) #8P155.........................................................................................Bell Housing 5) #8J041...........................................................................Bell Housing O-Ring 6) #MPDI196..............................................................................................Bypass 7) #8PJ066NPT.........................................................................Body Assembly 8) #8PJ068...................................................................Vacuum Breaker Valve 9) #8P168.........................................................................................................
