Product Overview
Built for continuous duty in hydronic climate control networks and facility water loops, the TPE3 40-470 inline centrifugal pump combines a 4 kW electric motor with close-coupled in-line architecture. Suction and discharge connections feature identical DN 40 porting, enabling direct drop-in placement within mechanical room pipe headers.
The hydraulic wet-end is engineered for optimal fluid dynamics, delivering 572 L/Min rated flow volume and reaching a maximum head capacity of 33.4 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 51.4 kg.
Configured for 3 x 380-500 V Three-phase power lines, the 4 kW drive motor draws 7.60 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 40 suction and DN 40 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 Composite impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.
