Pulsafeeder NextStep™ Precision Metering Pump — 317 GPD @ 58 PSI, 115 VAC
The Pulsafeeder NextStep™ NS7ASAKEEC3XXX is a precision metering pump built for high‑volume chemical dosing in water treatment and industrial systems. Its microprocessor‑controlled stepper motor ensures smooth, low‑pulsation flow and accurate output control.
This model includes a PVDF pump head with EPDM elastomers and ceramic check balls, ideal for alkaline and oxidizing chemicals. The standard control package supports manual, pulse, batch, and analog input modes.
Standard Control Features
- Manual output control using the front‑panel interface.
- Pulse input for water meters and dry‑contact pacing signals.
- Remote start/stop via external contact closure.
- Low‑tank‑level input for foot‑valve level switch monitoring.
- Analog input (0/4–20 mA or 0–10 VDC) for proportional control.
- Alarm relay output for external notification or interlocks.
- No Modbus or 4–20 mA output in the standard configuration.
Key Performance Advantages
- Max Flow Rate: 13.2 GPH / 317 GPD (50 LPH)
- Max Pressure: 58 PSI (4 BAR)
- NSF61 Certified for potable water applications
- Stepper‑motor drive for precise, repeatable feed control
- PVDF head with EPDM seals and ceramic balls for oxidizer compatibility
