Pulse Metering Pumps | Neptune Series PZ, PZi, PZiG Pulse Metering Pumps

PZD/PZi-32-52 High Capacity Pulse Metering Pumps Models

PZD Series pumps offer higher capacities. These model feature an extra large keyboard and the injection rate can be entered directly in millimeters per second.

The injection rate can be set three ways by direct entry of:

  • Stroke speed: 1 to 300 spm

  • Percentage: 1 to 100%

  • Injection rate: ml/min

High capacity models are available in material codes VFC, VEC, SS and FTC only. VFC model is shown.

  • Onboard calibration measures the actual discharge volume under the exact operating condition on the specific installation and chemical, then stores that value to ensure the correct injection rate.

  • Manual stroke length adjustment 20% to 100%

  • Set points can be easily viewed on the LCD

  • Pump hed may be rotated to face in any of three positions other than where the keypad and displau are located.

  • Pump head can be decoupled from the controller base for remote mounting

PZD/PZi-32-52 High Capacity Pulse Metering Pumps Models

PZiG Models offer capacities typically requiring motor driven pumps. Special models easily handle viscosities to 1000 CPS (up to 4000 CPS at reduced volume). Powerful onboard controls allow proportional flow rate, pH and residual chlorine control by direct analog connection eliminating the PID Controller and Inverter (plus the control panel tohouse them) that are required by similiar sized motor driven pumps.

The injection rate can be set three ways by direct entry of:

  • Stroke speed: 1 to 300 spm

  • Percentage: 1 to 100%

  • Injection rate: ml/min

  • Manual stroke length adjustment 20% to 100%

  • Onboard calibration measures the actual discharge volume under the exact operating condition on the specific installation and chemical, then stores that value to ensure the correct injection rate.

  • Multiple pump proportional flow rate injection from a single direct flowmeter signal (pulse/analog)

  • Two point leve switch control

  • Batch injection

  • Proportional control with shift and proportional band function

  • Two line LCD screen displays injection rate nad/or operational progress
