CombiNorm - Centrifugal Pump
CombiTherm ensures uniform process temperatures while keeping damaging heat away from seal faces and bearings. CombiTherm is designed to require no external cooling when working within the given parameters. The throttle bush, journal bearing and seal placement reduce circulation and temperature along the pump length. This greatly reduces the temperature at the seal face and bearings.
Suitable for
- Thermal oil heat transfer: OEM systems, maintaining temperature in jacketed equipment
- Marine and Floating Production Systems: Fuel tank heaters and fuel preheating, cargo and product heating, steam generation
- Food: Ovens, fish frying, distillation of fatty acids and glycerine, fat softening, potato chips, milk powder plants
- Bitumen: Asphalt production, roads and roofing
- Rubber and plastics: Injection molding, PVC tape, manmade fibers
- Chemical: Agitators, reactors, drying plants, polymerisation, plastics
- Paper and wood: Calender rolls, cardboard, washing machines, driers, floor board and wood panel
