Electroplating

In electroplating, many different chemicals are used. Therefore, chemical fluid handling is a very important part of any electroplating process. ProMinent has been supplying extremely reliable, low-maintenance components and systems to customers in this branch for years.

Overview

The broad product spectrum, coupled with the application knowledge of our engineers, makes ProMinent the ideal partner in the electroplating industry. The following products are typically used:

  • Storage tanks for chemicals
  • Chemical discharge pumps (barrel and transfer pumps)
  • Metering pumps
  • Measurement, control and sensor technology
  • Complete metering systems

These products are ideally suited for the electroplating industry and offer:

  • High reliability and therefore low maintenance costs
  • Safe handling of chemicals for both operator and process
  • Materials compatible with chemicals being used
  • Various types of sensors that are not dirt-sensitive
  • Low voltages (12 – 24 V) for use directly in the water
