Product Overview

Built for continuous duty in hydronic climate control networks and facility water loops, the TPE3 125-380 inline centrifugal pump combines a 15 kW electric motor with close-coupled in-line architecture. Suction and discharge connections feature identical DN 125 porting, enabling direct drop-in placement within mechanical room pipe headers.

The hydraulic wet-end is engineered for optimal fluid dynamics, delivering 3265 L/Min rated flow volume and reaching a maximum head capacity of 23.67 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 199 kg.

Configured for 3 x 380-480 V Three-phase power lines, the 15 kW drive motor draws 26.7 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 125 suction and DN 125 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 Cast iron impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.
  • Standardized DN 125 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.
