7. Experts in Chem-Feed and Water Treatment The NEW delta® series metering pump  Models:  3.1 gph @ 232 psi  5.3 gph @ 145 psi  7.9 gph @ 101.5 psi  13.2 gph @ 58 psi  21.1 gph @ 29 psi

8. Experts in Chem-Feed and Water Treatment optoDrive®  Keypad  optoDrive stroke measurement  Microprocessor electronic board  Power electronic board for solenoid drive  Solenoid 110 mm – isolated from housing

9. Experts in Chem-Feed and Water Treatment optoDrive®  Energy profile developed during calibration  Process pressure recognized in the first 20 strokes  Current (amps) to solenoid is stored as reference  Pushrod position is optically monitored & stored  During operation  Pump controls the energy profile of each stroke

10. Experts in Chem-Feed and Water Treatment optoGuard®  Integrated injection monitoring detects:  Gas airlocks  Broken discharge line  Blocked injection point  Variations in backpressure  Messages and alarm symbols displayed

11. Experts in Chem-Feed and Water Treatment Variable Suction Stroke  Slow suction stroke  Prevents:  Cavitation  Airlocks  Ensures:  Complete strokes  Smooth metering for sensitive media (e.g. enzymes)

12. Experts in Chem-Feed and Water Treatment Variable Discharge Stroke  Slow discharge stroke  Nearly continuous metering  Optimum mixing  Reduces vibration in discharge line  May eliminate the need for pulsation dampeners or static mixers  Fast discharge stroke for filling processes
