The CombiTherm Plus by SPX FLOW (Johnson Pump) is a heavy-duty, centerline-mounted centrifugal pump built to transfer hot thermal oils up to 660 °F (350 °C) and hot water up to 400 °F (200 °C) safely. It requires no external cooling systems while keeping seal faces cool
Core Design & Operation
- No External Cooling Needed: Internal throttle bushes, precise seal placement, and an optimized shaft-mounted cooling fan manage heat dispersion
- Low Seal Temperature: Large cooling fins and fans drop temperatures around the shaft seal below 220 °F (104 °C) even during high-heat operations.
- Centerline Mounting: Absorbs thermal expansion smoothly without throwing off shaft alignment.
- Modular Build: Shares standardized components with the wider Johnson Pump Combi system to reduce spare parts inventory
