In HVAC, cooling and refrigeration technology, reliable and continuous delivery of cooling and process fluids is essential. Schmitt centrifugal pumps are used in numerous peripheral applications in which fluids are transported for heat dissipation, system stabilisation or water treatment.

Typical applications include cooling water circuits in industrial cooling systems, the circulation of water-glycol mixtures and the operation of recooling systems and heat exchangers. In addition, the pumps perform important tasks in water treatment, such as the dosing of biocides, corrosion inhibitors or other chemical additives to ensure stable operating conditions.

Schmitt pumps are also used in open systems, such as return basins or collection tanks, as well as in auxiliary processes such as cleaning and disinfection. Key factors include their high chemical resistance to the fluids used and the ability to adapt different materials optimally to the respective requirements.

• Pumping of cooling water in closed and open cooling circuits
• Circulation of water-glycol mixtures for temperature control
• Use in recooling plants and cooling towers
• Pumping of fluids in heat exchangers and temperature control systems
• Circulation of heat transfer fluids in heating and cooling systems
• Use in chillers and industrial cooling units

• Use in cleaning and disinfection processes for cooling systems
• Pumping of demineralised water and treated water in sensitive cooling applications
• Use in collection tanks, return basins and buffer systems
• Integration into emergency cooling and redundancy systems
• Use in industrial process cooling systems with continuous operation

Centrifugal pumps are a central component of modern air-conditioning and cooling systems, as they convey fluids efficiently and uniformly. Schmitt centrifugal pumps are used primarily in supporting process steps, for example in cooling water systems, for the circulation of heat transfer fluids or in water treatment.

A key advantage of centrifugal pumps is their uniform, low-pulsation volumetric flow. This ensures stable temperature conditions and an even distribution of the cooling media within the system. At the same time, centrifugal pumps have a simple design, making them robust, durable and low-maintenance – important characteristics for systems in continuous operation.

In air-conditioning and refrigeration technology, operational reliability and material resistance play a decisive role. Schmitt pumps are therefore manufactured from corrosion-resistant plastics or stainless steel and are designed for use with water, glycol mixtures and chemical additives. Depending on the requirements, different designs are available, for example magnetic-drive, hermetically sealed pumps for the safe handling of critical fluids or dry-run capable immersion pumps for applications in open systems.
