NextStep

When reliability, accuracy and repeatability matter, NextStep stepper motor metering pumps allow for even distribution of chemical into your process. NextStep’s wide range of control and greatly reduced pulsation allow for reliable metering of off-gassing and viscous chemicals with extremely high accuracy. Backed by a five-year warranty that includes the diaphragm and communications options that keep your process running smoothly even from a remote location the NextStep metering pump assists critical applications in running effortlessly.

NextStep dosing pumps are designed for high-resolution metering control and reliability and cover a wide range of applications. The advanced microprocessor-driven stepper motor has a resolution of 4800:1 steps, allowing for digital control of both the discharge stroke and the suction stroke duration evenly distributing the chemical into the process. 

NextStep metering pumps give you the most accurate control over metering output, providing capacity control from 100% to 0.1% and suction stroke control from 100% to 30%. This Slow Mode feature increases the reliability of metering off-gassing and high-viscosity chemicals.

The advanced microprocessor-driven stepper motor has a 3,333:1 turndown ratio.  Digitally controlled discharge and suction stroke create a near-constant flow accuracy of feed. The steps are split up into a maximum of 4,800 steps to provide precise distribution of chemical throughout the full range eliminating the effects of pulsating flow and eliminating the cost of external devices such as static mixers and dampeners to overcome these effects.

Programming is simplified using a dial knob interface and intuitive symbols and prompts. A large easy-to-read, multi-color backlit display indicates pump status with four different backlight colors. The NextStep communications options keep your process running smoothly even from a remote location.

With complete control over dosing speeds and multiple operating modes to choose from, the operator can precisely set the flow rate required, meeting even extremely complex applications, and easily read it directly in GPH, LPH, and % on the graphic display.
