The 3 kW motor delivers a rated flow throughput of 457 L\/Min under continuous hydronic circulation.\u003c\/p\u003e\u003cp\u003eConstructed with an EN-GJL-250 cast iron casing, the housing body features cataphoresis electrocoating surface treatment for internal corrosion protection. The internal hydraulic assembly contains a precision bronze impeller fitted with bronze wear rings and a maintenance-free mechanical shaft seal. Net product weight measures 60.4 kg for fixed mounting placement in mechanical plant rooms.\u003c\/p\u003e\u003cp\u003eThe motor operates on a 415 V three-phase supply rated at 11 Amps nominal operating current. Operating liquid temperatures span from -25°C to 120°C under maximum working pressures up to 16 bar. In-line opposite port geometry with DN 50 flanged connections enables mounting directly into straight pipework lines or onto foundation bases.\u003c\/p\u003e\u003cp\u003eMotor protection features an IP55 enclosure rating with Class F thermal insulation and integrated PTC thermistors. Top-pull-out structural design enables removal of the motor head and impeller assembly without dismantling the pump housing from connected system pipework lines during scheduled servicing routines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStandardized DN 50 flanged connection ports for commercial HVAC and heating installation.\u003c\/li\u003e\n\u003cli\u003eInternal hydraulic rotor assembly incorporating a precision manufactured bronze impeller.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump casing with protective cataphoresis electrocoating surface treatment.\u003c\/li\u003e\n\u003cli\u003eRated hydraulic output capacity achieving 29 m maximum head and 457 L\/Min flow rate.\u003c\/li\u003e\n\u003cli\u003eIn-line structural design with opposite suction and discharge ports for direct pipework line mounting.\u003c\/li\u003e\n\u003cli\u003eTop-pull-out mechanical layout allowing service access without removing volute casing from pipework lines.\u003c\/li\u003e\n\u003cli\u003eIP55 enclosure rating with Class F thermal insulation and integrated PTC thermistor motor protection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBulk freight charges apply.
