The SPX Johnson Pump CombiTherm is developed especially for thermal oil (DIN 4754) and hot water applications EN12953-6 (DIN 4752) (ratings and dimensions to EN 733 (DIN 24255)). 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 bushing, journal bearing and seal placement reduce circulation and temperature along the pump length. This greatly reduces the temperature at the seal face and bearings. Typical liquid temperatures of 482° F (250°C) at the pump inlet will be as low as 212° F (100°C) at the seal faces.

  • Nodular cast iron construction

  • Long cooling length displacing seal away from the pumped liquid

  • Back vanes and labyrinth prevent solids from reaching bearing and seals

  • Product lubricated slide bearing

  • Standard mechanical seal
