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.
3,333:1 turndown
Accurate control from 100% down to 0.1% capacity with selectable Slow Mode for viscous applications.
Intuitive LCD
Multi-color backlight signals status: Standby (white), Working (green), Warning (yellow), Alarm (red).
Multiple control modes
0/4–20 mA, 0–10 V, pulse/PPM/%, batch, cycle timer, daily/weekly timer, or constant output.
Accuracy & Repeatability
±1% repeatability with nearly constant discharge for stable process control.
Handles Tough Chemistries
Reliable metering of off-gassing and viscous fluids; Slow Mode supports up to 1,000 cP.
Built for Duty
Continuous-duty rated, IP65 enclosure, quiet 52.8 dB operation.
Connectivity Ready
Standard Model: Does not include the optional RS-485/Modbus RTU; 4–20 mA output
