Grundfos TPE3 D 40-150-S cast iron 400V twin-head in-line pump
Twin-head, close-coupled in-line circulator with two identical power heads on a common cast iron housing. Each head carries an IE5 permanent-magnet motor with its own frequency converter, and the pair runs duty/standby with automatic alternation or in duty-assist at peak load.
TPE3 is factory fitted with a combined differential-pressure and temperature sensor, so it runs closed-loop control straight out of the box — no separate transducer to buy or wire.

Key features
Control modes
| AUTOADAPT | Default. The pump finds the lowest workable proportional-pressure curve for the system and keeps adjusting it. |
|---|---|
| FLOWADAPT | AUTOADAPT with a maximum flow limit — useful where flow must not exceed a design figure. |
| Proportional pressure | Head falls as flow falls. Suits radiator and two-pipe heating systems with thermostatic valves. |
| Constant pressure | Holds a fixed differential pressure regardless of flow. Suits underfloor heating and systems with low pipe losses. |
| Constant temperature | Controls speed to hold a set liquid temperature, e.g. domestic hot water return. |
| Constant curve | Fixed speed set from the control panel, Grundfos GO or an external signal. |
