The operating principle of the unit is based on positive displacement: a chrome-plated rotor rotates eccentrically inside a double-start spiral of a rubber stator, continuously displacing the water column from the suction chamber into the discharge pipe and creating a stable high pressure even in deep wells with a low flow rate.\u003c\/p\u003e\n\u003ch3\u003eMain advantages and features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChrome-plated spiral rotor:\u003c\/strong\u003e Made of alloy steel with a mirror finish polish and a protective galvanic layer, which minimizes friction inside the stator and protects the working edges from hydro-abrasive wear by sand suspensions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElastic rubber stator (NBR):\u003c\/strong\u003e High-density oil- and water-resistant rubber ensures tight contact with the screw ridges without excessive load on the motor, maintaining the tightness of the working cavities under high pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide thrust flange (∅78 mm):\u003c\/strong\u003e Guarantees precise coaxial fixation of the sleeve inside the pump part shell without misalignment or axial displacement during water hammers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced coupling with M14 left-hand thread:\u003c\/strong\u003e The adapter coupling is equipped with an M14 threaded mounting hole with a left-hand thread direction, which eliminates the risk of spontaneous unscrewing of the unit from the electric motor shaft during operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete factory pair:\u003c\/strong\u003e Supplied as an assembly (worm with coupling and matching sleeve), which guarantees perfect alignment of working clearances.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and application:\u003c\/h3\u003e\n\u003cp\u003eUsed for submersible screw pumps and borehole hydrophores of the QGDa \/ EVJ \/ EUJ size with a power of 750 W (0.75 kW):\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOmhiAqua:\u003c\/strong\u003e OHJ 2.5-60-0.75.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprut \/ Nasosy plus oborudovanie:\u003c\/strong\u003e ZGD\/ QGDa 2.5-60-0.75 (A08 series).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOmnigena:\u003c\/strong\u003e EVJ 2.5-60-0.75.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEuroaqua:\u003c\/strong\u003e EUJ 2.5-60-0.75, 4S QGD 2.5-60-0.75.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForwater:\u003c\/strong\u003e QGDa 2.5-60-0.75.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOther brands:\u003c\/strong\u003e Vodoley, Needle, Taifu, Kenle, Grandfar, Rona, Werk and other four-inch borehole screw pumps with a 78 mm stator mounting skirt and an M14 left-hand shaft thread.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical specifications:\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
