Product Overview
The TPE3 100-350 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 11 kW electric drive, the unit features inline DN 100 pipe connections that mount straight into active fluid transfer lines without requiring offset piping manifolds.
Hydraulic performance testing confirms a rated output volume of 2343 L/Min with an operational head rating of 23.8 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 143 kg.
The electric drive motor operates on a 3 x 380-500 V Three-phase power source drawing 20.3 Amps nominal operating current at 11 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 100 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 100 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.

Regulating fluid movement across primary-secondary headers, what peak flow capacity is sustained on site?
Varying volumetric velocity across building pipework, Grundfos TPE3 100-350 sustains a peak flow rate of approximately 2343 L/Min.
In terms of structural containment, what alloys form the volute and fluid-moving parts?
High-integrity casting quality in TPE3 100-350 is provided by an EN-GJL-250 cast iron body alongside an aerodynamically balanced cast iron impeller (EN-GJL-200).
Which electrical parameters in motor wattage, line voltage, and operational current run this pump?
Energy consumption for TPE3-100-350 is rated at 11 kW across a three-phase 415 V line with an operational current draw of 20.3 Amps.
For high-pressure installations, what liquid temperature span and working pressure are certified?
Process liquid temperatures spanning -25°C to 120°C are safely circulated by TPE3 100 350 under line pressures reaching 16 bar.
Adapting motor output across complex distribution runs, how high can this circulator propel media?
Dynamic elevation capacity certified for TPE3/100/350 reaches a peak delivery head of approximately 23.8 m.
