Product Overview
Built for continuous duty in hydronic climate control networks and facility water loops, the TPE3 50-450 inline centrifugal pump combines a 5.5 kW electric motor with close-coupled in-line architecture. Suction and discharge connections feature identical DN 50 porting, enabling direct drop-in placement within mechanical room pipe headers.
The hydraulic wet-end is engineered for optimal fluid dynamics, delivering 863 L/Min rated flow volume and reaching a maximum head capacity of 31.3 m. Cast iron housing materials (EN-GJL-250) provide reliable pressure containment under continuous duty cycles. A Composite impeller and BQQE seal drive liquid media across wetted passages. Net product weight measures 66.9 kg.
Configured for 3 x 380-500 V Three-phase power lines, the 5.5 kW drive motor draws 10.5 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 50 suction and DN 50 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
- EN-GJL-250 cast iron volute housing provides robust pressure containment up to 16 bar in demanding hydronic circulation loops.
- Corrosion-resistant Composite 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.
- Equal suction and discharge port diameters enable straightforward inline installation without requiring custom pipe reducer spools.

How much electrical wattage does this speed controlled motor consume under full operating current?
The permanent magnet drive fitted to Grundfos TPE3 50-450 operates on a three-phase 415 V line, consuming 5.5 kW with a current draw of 10.5 Amps.
Against high line pressure, what fluid temperature spectrum and peak working pressure are certified?
Thermal performance certified for TPE3 50-450 permits non-stop circulation with fluids between -25°C to 120°C at pressures to 16 bar.
Across variable flow distribution networks, how much vertical head pressure is maintained?
Regulating fluid momentum across secondary risers, TPE3-50-450 maintains a peak dynamic head of approximately 31.3 m.
Controlling liquid displacement through onboard electronics, what peak volume throughput is attained?
Modulating circulation rates across cooling branches, TPE3 50 450 sustains an operational throughput of approximately 863 L/Min.
What protective finishing and impeller engineering give this intelligent circulator its toughness?
The wet end assembly of TPE3/50/450 integrates a heavy cast iron casing with an engineered composite impeller (PES-GF30).
