Pulsafeeder NextStep™ Precision Metering Pump — 317 GPD @ 58 PSI, 115 VAC
The Pulsafeeder NextStep™ NS7AMAKVVT3XXX is engineered for high‑volume chemical feed systems requiring digital communication and remote monitoring. Its stepper‑motor drive ensures smooth, low‑pulsation flow and accurate metering across a wide turndown range.
This enhanced model adds Modbus RS‑485 and 4–20 mA analog output for SCADA and PLC integration. The PVDF head with FKM elastomers and TFE check balls provides excellent chemical resistance and low‑friction performance.
Advanced Control Features (Modbus + 4–20 mA Output)
- Modbus RS‑485 communication for full digital control and monitoring.
- 4–20 mA analog output for retransmitting pump speed, flow, or status.
- Manual output control via front‑panel interface.
- Pulse input for water meter pacing and dry‑contact signals.
- Remote start/stop through 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.
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 FKM seals and TFE balls for low‑friction dosing
