Product Overview
The TPE3 50-730 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 15 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 1168 L/Min with an operational head rating of 59.3 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 134 kg.
The electric drive motor operates on a 3 x 380-480 V Three-phase power source drawing 26.7 Amps nominal operating current at 15 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
- 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.
- Corrosion-resistant Cast iron impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.
- Standardized DN 50 flanged connections comply with EN 1092-2 for seamless drop-in integration into commercial pipe headers.
- Maintenance-free BQQE mechanical shaft seal prevents fluid leakage and maintains seal integrity under elevated working pressures.
- 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.

Through real-time flow tracking, how much circulating liquid volume can this intelligent pump move?
Across automated secondary manifolds, Grundfos TPE3 50-730 delivers an operational flow volume of approximately 1168 L/Min.
How are the wet end surfaces protected against chemical oxidation in closed heating loops?
Engineered for secondary distribution duty, TPE3 50-730 pairs an electrocoated cast iron shell with an aerodynamically balanced cast iron impeller (EN-GJL-200).
To sustain variable speed pumping, what motor rating, operating voltage, and amps are required?
Driven by an electronically commutated motor, TPE3-50-730 delivers 15 kW on a three-phase 415 V line with an operational current of 26.7 Amps.
Throughout seasonal hydronic cycles, which fluid thermal limits and pressure containment govern it?
Safe fluid containment is maintained by TPE3 50 730 for process liquids spanning -25°C to 120°C under working pressures of 16 bar.
Through real-time speed adaptation, how much dynamic elevation can this intelligent unit supply?
The variable frequency drive in TPE3/50/730 sustains a rated dynamic delivery head of approximately 59.3 m.
