The pump handles clean water fluid circulation across commercial HVAC distribution loops under continuous operation.\u003c\/p\u003e\u003cp\u003eThe hydraulic wet-end achieves a rated flow capacity of 439 L\/Min with a maximum head rating of 19 m. Cast iron housing materials provide solid pressure containment up to 16 bar. The internal assembly houses a bronze impeller fitted with bronze wear rings. Net equipment weight is 81.6 kg.\u003c\/p\u003e\u003cp\u003ePower specifications call for a 415 V three-phase electrical supply rated at 2.2 kW motor power. Current draw under load measures 4.4 Amps. Operating fluid temperatures span -25°C to 120°C with a maximum working pressure rating of 16 bar. The housing features opposite DN 50 flanged ports for mounting.\u003c\/p\u003e\u003cp\u003eThe electric motor carries an IP55 ingress protection rating alongside Class F thermal insulation and integrated PTC thermistors. System maintenance relies on top-pull-out architecture, enabling drive head disassembly while the pump casing stays secured to pipe runs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2.2 kW motor driving a bronze impeller to produce 439 L\/Min at 19 m head.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron volute with cataphoresis electrocoating for hydronic loop service.\u003c\/li\u003e\n\u003cli\u003eOpposite DN 50 flanged ports enabling direct insertion into commercial pipework runs.\u003c\/li\u003e\n\u003cli\u003e4.4 Amps rated current draw at 415 V three-phase supply voltage.\u003c\/li\u003e\n\u003cli\u003eBQQE mechanical shaft seal with bronze wear rings for clean water circulation duty.\u003c\/li\u003e\n\u003cli\u003eIP55 motor enclosure rated for dust and water spray protection in plant room environments.\u003c\/li\u003e\n\u003cli\u003eTop-pull-out structural design permitting service access without disturbing pipework connections.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBulk freight charges apply.
