In surface finishing, a wide range of components, wires or sheets are provided with durable, usually metallic coatings using electrochemical, electroplating or electroless wet-chemical processes.
These coatings are used, for example, for corrosion and wear protection. They are also applied for visual and design reasons. In coating systems, the components pass through a sequence of immersion tanks containing various chemicals for cleaning, coating and rinsing. 

Various aggressive fluids are used in this process, which is why the filling, circulation and draining of the tanks can only be carried out with appropriately chemically resistant pumps.

This is where our centrifugal pumps fully demonstrate their strengths. They are resistant to the chemicals used and operate reliably. They also integrate seamlessly into our customers’ system architecture.

• Electroplating systems, circulation of electroplating baths
• Electroless chemical coatings, e.g. electroless nickel
• Pickling plants

• Degreasing systems
• Washing systems

Centrifugal pumps are an essential component of electroplating plants, as they convey process fluids continuously and uniformly. Schmitt centrifugal pumps are specifically designed for use with aggressive and often toxic fluids and ensure safe and stable operation in surface finishing technology.

A key advantage is the uniform, low-pulsation volume flow. This ensures constant process conditions, for example when circulating electrolyte baths or in rinsing processes, and thus contributes to uniform coating quality. At the same time, the robust design enables long-lasting, low-maintenance operation in plants with high utilisation.

In electroplating technology, leak tightness is particularly important. Magnetic drive pumps from Schmitt operate hermetically sealed and reliably prevent the escape of hazardous fluids. Alternatively, pumps with mechanical seals provide an economical solution for less critical applications. In addition, dry-run capable immersion pumps enable safe use in open basins and tanks.

Thanks to their high chemical resistance, operational reliability and flexibility, Schmitt centrifugal pumps can be optimally integrated into electroplating process lines – from electrolyte circulation and rinsing processes through to wastewater treatment and the recirculation of process fluids.
