Hendor has been serving the pre-treatment powder coating & galvanising industry for 10 years. Our most reliable and effective pumps & filters for pre-treatment lines contribute to a significant enhanced machine reliability and uptime.
Powder coating pre-treatment is a chemical process which prepares a surface to be effectively powder coated. The process entails chemical treatment to take off all dirt and oxides. As a next step, a chemical treatment is given to create an intermediate conversion coating to enhance corrosion resistance and adhesion. Besides pre-treatment in a spray tunnel, also dip pre-treatment is commonly used in the surface finishing industry.
Galanising entails the process of applying a zinc coating to an iron or steel surface. This coat will prevent the metal from rusting. Most common way to apply this method is via hot dip galvanizing, in which parts are dipped in a bath of hot, molten zinc.
To achieve good quality coatings with powder coating and hot dip galvanising, a wet chemical pre-treatment is a necessity. The application process of this pre-treatment requires reliable, high performance pumps and filters.
Smart technology from Hendor for the pre-treatment industryHendor offers various pump- and filtration solutions for the pre-treatment powder coating and galvanising industry:
- In the powder coating industry, the pre-treatment spray tunnel is mostly seen. To feed the nozzles in the pre-treatment spray tunnel, Hendor vertical pumps have proven their reliability and service life.
- To keep the nozzles open, and the spray tunnel and the chemical solution clean, our adsorption filtration system takes out all dirt particles. This leads to significant reduced rejection rates, re-work, maintenance and chemical consumption.
- For the dipping tanks seen in both the hot dip galvanising and powder coating industry, Hendor offers various pump and filtration solutions for the pre-treatment applications. Horizontal centrifugal pumps both with magnetic drive or mechanical seal technology for bath agitation, circulation and chemical transfer in PP, PVDF, or Stainless Steel 316. Besides in the production line, these pumps also find their application in the waste water treatment plant.
- For those applications where maximum reliability and durability is required, Hendor offers sealless and bearingless vertical pumps in PP, PVDF, or Stainless Steel 316. The Hendor vertical pumps can typically run for many years without any maintenance.
Most suitable pumps and filters for your pre-treatment lineWith Hendor pumps and filters in your pre-treatment line, you can rely on maximum uptime and minimum rejection rates, providing reliability and minimal Total Cost of Ownership. All our products are easy to maintain with spare parts guaranteed available for at least next 10 years.
