Product Overview
The TPE3 50-240 in-line centrifugal pump is specified for clean water circulation across commercial heating and cooling installations, district energy plants, and industrial utility headers. Operating with a 2.2 kW electric drive, the unit features inline DN 50 pipe connections that mount straight into active fluid transfer lines without requiring offset piping manifolds.
Hydraulic performance testing confirms a rated output volume of 552 L/Min with an operational head rating of 19.6 m. The EN-GJL-250 cast iron volute casing handles system line pressures up to 16 bar. Internal fluid movement is driven by a durable Composite impeller fitted with a BQQE mechanical seal. Product net weight equals 29.4 kg.
The electric drive motor operates on a 3 x 380-500 V Three-phase power source drawing 4.35 Amps nominal operating current at 2.2 kW drive output. The pump processes clean, non-aggressive fluids across liquid temperatures between -25°C to 120°C under maximum working pressures up to 16 bar. Flanged connections feature matching DN 50 inlet and outlet porting.
Built with an IP55 dust and moisture resistant motor enclosure, the unit features Class F thermal insulation for reliable continuous duty. An integrated variable frequency drive (VFD) and PI controller adjust motor speed dynamically to match real-time flow demand. Servicing is simplified by the top-pull-out architecture, allowing removal of the motor head and rotating assembly without disturbing main line pipe joints.
Features
- IP55 motor enclosure protection guards internal electrical components against ambient dust accumulation and water splash ingress.
- Class F thermal motor insulation permits continuous operation under elevated fluid temperatures ranging from -25°C to 120°C.
- Equal suction and discharge port diameters enable straightforward inline installation without requiring custom pipe reducer spools.
- Integrated variable frequency converter with PI controller modulates motor RPM dynamically to balance flow demand and lower energy usage.
- Top-pull-out structural layout enables complete drive head and impeller extraction without disconnecting the pump casing from system piping.
- High-efficiency motor design delivers optimized hydraulic throughput with minimal electrical power consumption across variable duty cycles.
- EN-GJL-250 cast iron volute housing provides robust pressure containment up to 16 bar in demanding hydronic circulation loops.

Responding to fluctuating thermal loads, how much fluid volume can this intelligent circulator move?
Adapting volumetric output across diverse zones, Grundfos TPE3 50-240 maintains a maximum discharge throughput of approximately 552 L/Min.
How does the material composition of this unit maintain hydraulic shape across duty cycles?
Cataphoresis electrocoating protects the outer casing of TPE3 50-240, which drives fluid using an engineered composite impeller (PES-GF30).
What electrical input specifications in kilowatts, voltage profile, and current govern this unit?
Under full electrical frequency, TPE3-50-240 consumes 4.35 Amps from a three-phase 415 V supply to run its 2.2 kW motor drive.
Across secondary heating loops, what liquid temperatures and working pressures are supported?
Accommodating demanding temperature cycles from -25°C to 120°C, TPE3 50 240 maintains seal integrity under working pressures to 16 bar.
Under variable volume pumping duty, what total vertical elevation column can this unit overcome?
Adapting rotational velocity to zone requirements, TPE3/50/240 attains a maximum dynamic lift of approximately 19.6 m.
