  • Page 7: Description

    1. DESCRIPTION NextStep is a mechanically actuated, stepper motor driven diaphragm dosing pump with multiple 1.1 NEXSTEP Series control functions. The microprocessor controlled stepper motor ensures a homogeneous dosing process. The position and the speed of the diaphragm is controlled by the microprocessor electronics during the entire discharge/suction cycle.

  • Page 8: Working Modes

    Pump can work in different ways: 1.2 Working modes MODE WORKING MODES Pump doses at a constant rate set in “LPH” (liters per hour) or GPH CONSTANT (gallons per hour), during setup session. OZ PER PULSE The pump doses the quantity of product set for each impulse received. Dosing rate is determined by pulses from a water meter based on a PPM setpoint and chemical product concentration (%).
