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
