Product Overview
The TPE3 80-570 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 22 kW electric drive, the unit features inline DN 80 pipe connections that mount straight into active fluid transfer lines without requiring offset piping manifolds.
Hydraulic performance testing confirms a rated output volume of 2238 L/Min with an operational head rating of 48.6 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 Cast iron impeller fitted with a BQQE mechanical seal. Product net weight equals 159 kg.
The electric drive motor operates on a 3 x 380-480 V Three-phase power source drawing 39.2 Amps nominal operating current at 22 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 80 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.

Under closed-loop flow optimization, what maximum fluid delivery rate is certified for this unit?
Controlled liquid momentum produced by Grundfos TPE3 80-570 yields an operational flow throughput of approximately 2238 L/Min.
Which structural alloys give this variable frequency circulator its physical ruggedness?
Resisting operating wear across process headers, TPE3 80-570 combines a cataphoresis-treated cast iron body with an aerodynamically balanced cast iron impeller (EN-GJL-200).
To operate the electronic drive system, what motor kilowatts, supply voltage, and amps are needed?
Full load running amperage for TPE3-80-570 reaches 39.2 Amps from a three-phase 415 V supply to power its 22 kW variable speed drive.
For thermal expansion management, which liquid temperature limits and working pressures apply?
System engineers can circulate fluid media from -25°C to 120°C using TPE3 80 570 under working pressures up to 16 bar.
Controlling loop velocity through onboard electronics, what total dynamic head is sustained on site?
Supplying proportional pressure to multi-story manifolds, TPE3/80/570 sustains an elevation of approximately 48.6 m.
