Grundfos TPE3 150-230-S cast iron 400V single-head in-line pump

Single-stage, close-coupled in-line circulator with an IE5 permanent-magnet motor and integrated frequency converter. Speed varies continuously to match system demand, so the pump draws only the power the duty actually needs.

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

Built-in sensor

The combined differential-pressure and temperature sensor is fitted at the factory, so closed-loop control needs no extra transducer, cabling or set-up.

IE5 permanent-magnet motor

Exceeds the IE5 threshold of IEC 60034-30-2, with materially lower running cost than an equivalent fixed-speed induction pump.

Heat energy monitoring

Flow and temperature readings let the pump estimate heat energy delivered — useful for balancing, commissioning and spotting system faults.

Top-pull-out servicing

Motor, pump head and impeller lift out as one assembly while the housing stays in the pipework.

BMS ready

GENIbus and analogue/digital I/O as standard, with optional Grundfos CIM modules for BACnet, Modbus and other building protocols.

Grundfos GO

Commission, read status and change set points from a phone or tablet with the Grundfos GO app.

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.

Frequently asked questions

Do I need to buy a pressure sensor?

No. TPE3 pumps have a combined differential-pressure and temperature sensor fitted at the factory, so proportional-pressure, constant-pressure and AUTOADAPT control work without any extra parts.

What is the difference between TPE2 and TPE3?

Both use IE5 permanent-magnet motors with integrated speed control. TPE2 has no sensor and needs an external transducer for closed-loop control; TPE3 has the sensor built in and adds heat energy monitoring.

Is this the single-head or twin-head version?

Single head. The twin-head equivalent is the TPE3 D 150-230, which we list separately.

What supply does it need?

3 x 400 V, 50 Hz. This size is three-phase only — there is no single-phase version.

What is the lead time?

This size is not a standard stock item. Contact us before ordering and we will confirm the current lead time from Grundfos.
