Advanced diaphragm pump technology for unmatched flow control
Pulsafeeder® NextStep™ precision metering pumps deliver higher turndown ratios with minimal pulsation effects.
Get next-generation precision and reliability that builds on Pulsafeeder’s trusted chemical pump solenoid technology with superior stepper motor performance. Featuring an industry-leading 3,333:1 turndown ratio, 4800-step resolution, and innovative suction stroke control, the accurate, reliable NextStep dosing pump is ideal for water treatment, chemical processing, and manufacturing applications.
A positive displacement pump, NextStep’s unmatched digital flow control solves key challenges:
- Eliminates pulsation effects without additional equipment.
- Handles difficult chemicals with ease.
- Integrates seamlessly into your existing systems, providing flexibility and operational continuity.
Trusted stepper motor dosing pump reduces downtime, costs, complexity
Building on Pulsafeeder’s fluid handling expertise, the NextStep precision metering pump’s advanced stepper motor technology delivers near-constant chemical feed with outstanding flow precision—reducing system complexity and improving process results without the external dampeners or mixers often needed with traditional metering solutions.
Handle your most challenging chemicals with confidence
Our chemical metering pump’s innovative “Slow Mode” feature gives you precise control over both discharge (100% to 0.1%) and suction stroke (100% to 30%), ensuring reliable metering of problematic off-gassing chemicals and high-viscosity fluids up to 20,000 cPs that cause conventional diaphragm pumps to fail. This digital control of both strokes creates exceptional flow accuracy throughout the electric diaphragm pump’s entire operating range.
Intuitive chemical pump operation meets powerful control options
Programming NextStep metering dosing pumps is effortless with the dial knob interface, intuitive symbols, and color-coded display that instantly communicates pump status. Flow rates can be easily read directly in GPH, LPH, and percentage on the graphic display, and multiple operating modes—proportional control via 4-20mA or pulse input, constant output, timer functions, and batch control—provide the versatility to configure a one-pump platform for numerous applications.
Integrate seamlessly with existing systems
Comprehensive input/output options on our chemical dosing pump—including water meter pulse input, 4-20mA/0-10VDC signals, and alarm relay outputs—enable seamless integration with your existing control systems, all accessible even from remote locations.
