FlexFlow and NanoP

Complete pH Adjustment System

DEMA’s FlexFlow pump is the ideal solution for greenhouses, orchards, and any other agricultural applications to deliver acids and virtually any chemical directly into pressurized water lines. The FlexFlow pump is typically used in conjunction with the NanoP, a state-of-the-art controller that can vary chemical volumes based on water flow and/or pH for a precise downstream solution.

The NanoP controller can be utilized with the included pH probe to provide a complete pH control solution. This combo is typically used to inject an acid to lower the pH of water used for irrigation, but can also inject chemicals to raise pH or treat the water. The NanoP also has the ability to control two FlexFlow pumps, if an application requires pH to be adjusted in both directions. The NanoP also offers integration with a wide variety of flow meters and flow switches to tailor the system to your exact needs. The NanoP can output a pulse signal, a 4-20mA signal, or control the two 120 VAC onboard relays to trigger a pump. Please contact us with any questions you may have about integrating a NanoP Controller and FlexFlow Pump into your irrigation system for pH control or water treatment.
