General Purpose Surface Pumps >> WZB - Automatic Boosting Pumps

WZB automatic self-priming smart boosting pump sets, consist of self-priming peripheral pumps, quality pressure tanks, electronic control unit and other accessories. Pump set could be working under two working model:

Model I: Total Heading Working Model: by set the minimum starting pressure (o.5-6bar), no need to set stop pressure, pump will turn on running when the pressure decreases to pre-set minimum starting pressure; pump will stop running when the flow rate less than minimum required flow rate.
Model II: High-low Pressure Working Model: pumps running at this model, you could set the Max. High pressure (stop pressure) and Minimum low pressure (start pressure), pumps will be running to keep the pressure between the high and low pressure.

Features:

  1. Man-machine interactive interface technology with digital display screen, easy to set all the data and easy operation.
  2. The motor designed for starting at low voltage and full loading, for rated voltage 230V, pump could running at 160V.
  3. Small flow rate motor protection technology to solve the motor heating problem which caused by frequent starting because of small flow rate.
  4. Anti-block system, for long term not running pumps, pumps will running a few second at regular intervals to avoid blocking because of rust or deposit.
  5. With over-current protection and over-heat protection.
  6. Integrated with surge tank.


Technical Data of Electronic Control Unit:

  1. Rated voltage: 110V or 220-240V, 60 or 50Hz
  2. Max. Working Pressure: 10 bar
  3. Liquid temperature: 0-80℃
