Heating & Cooling technology
Heating and cooling technology companies see themselves confronted by the following challenges
- Controlling extremely high or extremely low temperatures
- High requirements in terms of safety, health and environmental protection
- Economical and sustainable concepts
- High and reproducible quality of end products and processes
- Adherence to legal specifications
We support your company in realising safe and economical solution concepts for temperature-supported processes – for use in both smaller devices and in large industrial plants.
Application examples for our liquid pumps
- Heating industrial processes, including ovens (or furnaces), calenders, boilers and large deep-fat fryers up to +400 °C
- Cooling of industrial processes up to -100 °C
- Tempering rollers, e.g. in mangle systems and the printing industry
Application ranges
- Oils -100 to +350 °C
- Hot water up to +180 °C
Centrifugal pumps in modular systems with standard sizes
- Developed for heat transfer systems as per DIN 4754
- Bearing bracket sizes 360 and 470, PN 16
- Uncooled mechanical seals with dry-run safety function or magnetic coupling with start-up safety device
- Robust bearings
- For larger sizes: centreline casing mounting and casing with double volute
- Smart and efficient dissipation of heat from bearings and seals
- Suitable for continuous operation
- Safe operation and reliable in the following areas of application
- Thermal oil pumps
Mineral and synthetic thermal oils, silicon oils
Design in spheroidal graphite cast iron for temperatures from -40 to +350 °C (up to +400 °C upon request)
Design in stainless steel for temperatures from -100 to +250 °C - Hot water pumps with uncooled mechanical seals
Design in spheroidal graphite cast iron for temperatures up to +160 °C (+180 °C upon request)
Regenerative turbine pumps
- Heat transfer pumps or thermal oil pumps from -40 to +350 °C
- Hot water pumps up to +220 °C
- Pressures up to 30 bar, higher pressures upon request
Side channel pumps
- Temperatures from -100 to +350 °C
- E.g. for delivering cooling brine or for filling and emptying thermal oil systems
