Neptune Electronic Metering and Dosing Pumps



Accurate and precise electronic metering pumps

Neptune electronic metering pumps are designed for accurate, reliable injection of a wide variety of liquids. The pumps can be easily integrated into existing chemical metering systems and feature an air release valve that allows the pumps to be used in sodium hypochlorite service or with other chemicals that off-gas at room temperature.

Typical industries and applications include chemical processing, pH control, industrial and municipal water treatment, pulp and paper manufacturing and anywhere that required accurate and reliable dosing.

Range includes

  • PZ – manual control
  • PZD – manual control with stroke length adjustment
  • PW – pulse signal / analogue signal
  • PZi4 – external input
  • PZi8 – programmable inputs/outputs
  • PZiG – high volume programmable inputs/outputs
