Grundfos TPE3 80-440 Cast Iron Variable Speed Three Phase Inline Centrifugal Pump with Cast Iron Impeller

Built for continuous duty in hydronic climate control networks and facility water loops, the TPE3 80-440 inline centrifugal pump combines a 11 kW electric motor with close-coupled in-line architecture. Suction and discharge connections feature identical DN 80 porting, enabling direct drop-in placement within mechanical room pipe headers.

The hydraulic wet-end is engineered for optimal fluid dynamics, delivering 1817 L/Min rated flow volume and reaching a maximum head capacity of 30.6 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 116 kg.

Configured for 3 x 380-500 V Three-phase power lines, the 11 kW drive motor draws 20.3 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 80 suction and DN 80 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.
