In surface engineering, a wide range of components, wires or sheets are coated with durable, usually metallic coatings using electrochemical, galvanic 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 the coating systems, the components pass sequentially through a series of immersion tanks containing various chemicals for cleaning, coating and rinsing. 

Various aggressive fluids are used in this process, which is why filling, circulating and emptying 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. In addition, they integrate perfectly into our customers’ system architecture.

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

• Degreasing systems
• Washing systems

Centrifugal pumps are an essential component of electroplating systems, 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 treatment technology.

A key advantage is the uniform, low-pulsation volumetric flow. This ensures constant process conditions, for example when circulating electrolyte baths or in rinsing processes, and therefore contributes to uniform coating quality. At the same time, the robust design enables long service life and low-maintenance operation in systems 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 offer 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.
