Wherever aggressive, corrosive or toxic fluids are conveyed in the chemical industry, Schmitt centrifugal pumps provide reliable and safe solutions. Typical areas of application include the transfer of acids and lyes between tanks and process systems, the feeding of reactors, and the circulation of process fluids in closed circuits.

Another key area of application is the pumping of chemicals in secondary and auxiliary processes, for example in wastewater treatment, neutralisation or gas scrubbers. Here, fluids often have to be transported continuously and under demanding conditions. 

Schmitt pumps are also used for dosing additives or conveying high-purity fluids – for example in semiconductor or battery production.

Of particular importance in the chemical industry is the absolute leak-tightness of the systems. Many Schmitt pumps are therefore magnetic drive pumps and operate hermetically sealed, preventing leakage even with hazardous or environmentally critical fluids. At the same time, various materials such as PVDF, PP, ETFE, PFA or stainless steel enable optimum adaptation to a wide range of chemical requirements.

• Pumping acids and lyes in production and transfer processes
• Use in tank farms and handling processes (filling, emptying, transferring)
• Circulation and recirculation of aggressive chemicals in reactors and process circuits
• Pumping corrosive, toxic or environmentally hazardous liquids in closed systems

• Use in dosing and mixing processes for chemical additives and process fluids
• Pumping of high-purity and process water in chemical production plants
• Pumping of heat transfer fluids in thermal processes
• Use in cooling circuits in chemical plants (e.g. for reactor cooling)

Centrifugal pumps are among the key components in the chemical industry, as they convey fluids continuously and reliably. Schmitt centrifugal pumps are specifically designed for use with aggressive, toxic and high-purity media and are used in both main and auxiliary processes.

A key advantage of centrifugal pumps is their uniform, low-pulsation flow. This ensures stable process conditions, for example when feeding reactors, in cooling circuits or in the continuous transfer of chemicals. At the same time, the robust and comparatively simple design enables long service life and low-maintenance operation – an essential factor in plants with 24/7 production.

In the chemical industry, safety and resistance are key priorities. Schmitt pumps are therefore manufactured from highly corrosion-resistant plastics or stainless steel and are designed for use with demanding fluids. Magnetic drive series ensure leak-free operation, while versions with a mechanical seal or double-acting seal provide additional flexibility for different process requirements.

Another advantage is the high versatility of the portfolio. From dry-run capable immersion pumps and robust stainless steel pumps through to highly resistant standardised chemical pumps, Schmitt centrifugal pumps can be precisely adapted to the respective application – whether for transfer processes, circulation, dosing tasks or integration into complex process engineering plants.
