Product Overview
Operating on a 11 kW motor drive, the TPE3 50-700 single-stage inline pump handles fluid transfer across commercial building services, cooling tower circuits, and hydronic heating headers. Standardized DN 50 suction and discharge flanges permit inline line mounting, eliminating complex foundation coupling procedures.
Liquid handling performance provides a nominal flow rate of 1042 L/Min against a maximum head limit of 48.5 m. The cast iron volute body (EN-GJL-250) offers corrosion barrier protection for hydronic loops. The internal rotor houses a Cast iron impeller assembly supported by a BQQE shaft seal. Equipment net weight stands at 109 kg.
Engineered for Three-phase electrical systems (3 x 380-500 V), the 11 kW motor draws 20.3 Amps full-load current. Operating liquid temperatures cover a wide -25°C to 120°C span up to 16 bar system working pressure. Opposite DN 50 inlet and DN 50 discharge flanges provide standard pipe header compatibility.
Enclosure protection meets IP55 weatherization standards, supported by Class F motor insulation against high ambient temperatures. An onboard frequency converter with closed-loop PI control allows real-time variable speed tuning. The top-pull-out power head geometry permits technicians to perform seal or impeller maintenance while keeping the volute casing installed in system pipework headers.
Features
- 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.
- Standardized DN 50 flanged connections comply with EN 1092-2 for seamless drop-in integration into commercial pipe headers.
