Featuring equal suction and discharge porting (DN 80), this unit connects directly into vertical or horizontal header pipe runs across HVAC plant rooms, district heating loops, and commercial water circuits.\u003c\/p\u003e\u003cp\u003eUnder nominal duty conditions, the wet-end hydraulic assembly generates a rated flow capacity of 698 L\/Min alongside a maximum operational head limit of 7.2 m. The volute housing is constructed from EN-GJL-250 cast iron to ensure high structural pressure containment up to 16 bar. Inside, a precision-balanced Composite impeller works in tandem with a BQQE mechanical shaft seal. Net equipment weight measures 33.6 kg.\u003c\/p\u003e\u003cp\u003eElectrical power for the TPE3 80-120 pump is supplied by a 1 x 200-240 V Single-phase electrical connection drawing 6.7 Amps under full load. The unit accommodates operating fluid media temperatures ranging from -25°C to 120°C under continuous line pressure ratings up to 16 bar. Pipework mounting is supported by opposite DN 80 inlet and DN 80 outlet flanged connections.\u003c\/p\u003e\u003cp\u003eMotor protection complies with IP55 enclosure standards to guard internal windings against dust and moisture ingress, backed by Class F thermal insulation. An integrated frequency converter and PI controller provide continuously variable speed regulation to optimize energy consumption against system demand. The top-pull-out structural layout permits maintenance technicians to withdraw the motor drive and impeller assembly without unbolting the pump volute from connected system pipework flanges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrated variable frequency converter with PI controller modulates motor RPM dynamically to balance flow demand and lower energy usage.\u003c\/li\u003e\n\u003cli\u003eTop-pull-out structural layout enables complete drive head and impeller extraction without disconnecting the pump casing from system piping.\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency motor design delivers optimized hydraulic throughput with minimal electrical power consumption across variable duty cycles.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron volute housing provides robust pressure containment up to 16 bar in demanding hydronic circulation loops.\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant Composite impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.\u003c\/li\u003e\n\u003cli\u003eStandardized DN 80 flanged connections comply with EN 1092-2 for seamless drop-in integration into commercial pipe headers.\u003c\/li\u003e\n\u003cli\u003eMaintenance-free BQQE mechanical shaft seal prevents fluid leakage and maintains seal integrity under elevated working pressures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBulk freight charges apply.
