Stepper-Motor Precision 3,333:1 Turndown ±1% Repeatability 5-Year Diaphragm Warranty IP65 NSF/ANSI/CAN 61
NextStep™ Digital Dosing Pump
High-resolution metering with microprocessor-driven stepper motor control for smooth, accurate chemical feed—even with off-gassing or viscous chemicals.
Why NextStep
Ultra-smooth flow
Stepper control of suction & discharge strokes reduces pulsation for consistent discharge across the full range.
