Wherever aggressive, corrosive or toxic liquids are handled in the chemical industry, Schmitt centrifugal pumps provide reliable and safe solutions. Typical applications 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 application area is the handling of chemicals in ancillary and auxiliary processes, for example in wastewater treatment, neutralisation or gas scrubbers. In these applications, fluids often have to be transported continuously and under demanding conditions. 

Schmitt pumps are also used for dosing additives or transferring 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 therefore feature a magnetic drive and operate hermetically sealed, so that no leaks occur even with hazardous or environmentally critical fluids. At the same time, different materials such as PVDF, PP, ETFE, PFA or stainless steel enable optimal adaptation to a wide range of chemical requirements.

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

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

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

A decisive advantage of centrifugal pumps is their uniform, low-pulsation flow. This ensures stable process conditions, for example when feeding reactors, in cooling circuits or during 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.

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