Product Overview
Built for continuous duty in hydronic climate control networks and facility water loops, the TPE3 100-540 inline centrifugal pump combines a 18.5 kW electric motor with close-coupled in-line architecture. Suction and discharge connections feature identical DN 100 porting, enabling direct drop-in placement within mechanical room pipe headers.
The hydraulic wet-end is engineered for optimal fluid dynamics, delivering 2757 L/Min rated flow volume and reaching a maximum head capacity of 34.3 m. Cast iron housing materials (EN-GJL-250) provide reliable pressure containment under continuous duty cycles. A Cast iron impeller and BQQE seal drive liquid media across wetted passages. Net product weight measures 172 kg.
Configured for 3 x 380-480 V Three-phase power lines, the 18.5 kW drive motor draws 33.0 Amps during nominal full-load duty. Thermal operational limits support fluid handling from -25°C to 120°C across commercial hydronic networks. Connection to plant room headers relies on inline DN 100 suction and DN 100 discharge flanges.
Winding insulation complies with Class F standards within an IP55 rated motor enclosure designed for demanding plant room environments. Equipped with an onboard frequency converter and PI controller, the pump modulates motor RPM dynamically for maximum energy efficiency. Top-pull-out casing construction enables service personnel to extract drive components without disconnecting suction or discharge flanges.
Features
- 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.
- Corrosion-resistant Cast iron impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.

What power output, electrical supply configuration, and full load amperage govern this drive?
The integrated inverter motor in Grundfos TPE3 100-540 provides 18.5 kW of mechanical power, requiring a three-phase 415 V line pulling 33.0 Amps.
Under extreme temperature variations, what thermal operating range and pressure capacity are provided?
Fluid media temperatures between -25°C to 120°C are accommodated by TPE3 100-540 without compromising its 16 bar pressure rating.
Through electronic inverter drive control, what maximum vertical elevation column is delivered?
Across secondary distribution headers, TPE3-100-540 provides a maximum dynamic lift rating of approximately 34.3 m.
Across variable hydronic pipework, what maximum flow volume is delivered under peak frequency?
Across high-capacity secondary headers, TPE3 100 540 provides a maximum volumetric flow rate of approximately 2757 L/Min.
Under intense hydraulic operation, which metals protect the internal runner and outer body?
The rigid pressure envelope of TPE3/100/540 combines an EN-GJL-250 cast iron casing with an aerodynamically balanced cast iron impeller (EN-GJL-200).
