Grundfos TPE3 D 100-160-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

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.

Duty and standby built in

The heads alternate automatically to share running hours; the standby head starts on fault, and both can run together for peak demand.

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?

Twin head. The single-head equivalent is the TPE3 100-160, 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.

What types of Grundfos pumps are available?

Grundfos offers circulators, booster pumps, borehole pumps, drainage pumps and other solutions for domestic and commercial systems.

How do I identify the correct Grundfos pump model?

Use the model name and product number on the pump nameplate, then check the electrical, hydraulic and connection specifications.

Can a Grundfos pump improve household water pressure?

A suitably selected Grundfos booster system can improve water pressure or flow, subject to the property’s water supply and installation requirements.
