The NEW delta® series metering pump

Technical Features & Benefits Applications Demonstration


delta® Features

Single drive for the entire series Uniquely specifiable Economical alternative to Sigma/1 Capacities in line with LMI “C” Series Eliminates need for many accessories Controllable suction and discharge stroke duration Minimal moving parts



Featuring optoDrive control Capacity 3.2 gph @ 232 psi up to 21 gph @ 29 psi Turndown ratio 36,000:1 on stroke & frequency

Maximum frequency = 200 strokes per minute Minimum 1 stroke/hr = 12,000:1 turndown Minimum 30% stroke length = 3:1 turndown

PVT and SST liquid ends only Smallest 3 sizes – gala/beta



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

isolated from housing


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


optoGuard®

Integrated injection monitoring detects: Gas airlocks Broken discharge line Blocked injection point Variations in backpressure

Messages and alarm symbols displayed


Variable Suction Stroke

Slow suction stroke

Prevents: Cavitation Airlocks

Ensures: Complete strokes Smooth metering for sensitive media

(e.g. enzymes)


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


Flexible chemical feed capabilities
