The mechanism consists of a metal spiral worm with a coupling and an elastic rubber sleeve with a spiral internal channel. When the rotor rotates, the liquid moves continuously along the axis from the suction part to the discharge pipe, creating high pressure even at low water flow rates.\u003c\/p\u003e\n\u003ch3\u003eKey Advantages and Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWear-resistant chrome coating of the rotor:\u003c\/strong\u003e The metal screw is made of durable steel with a polished anti-corrosion coating, which reduces friction and extends the part's service life when pumping water with silt or fine sand impurities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElastic wear-resistant rubber:\u003c\/strong\u003e The sleeve (stator) is made of high-density oil-and-gas resistant technical rubber, ensuring 100% tightness of the working cavities and high pump efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReady-to-use repair kit:\u003c\/strong\u003e Supplied as a complete assembly (screw worm with adapter coupling and matching rubber sleeve with mounting flange), which eliminates issues with fitting dissimilar parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardized mounting dimensions:\u003c\/strong\u003e Precise matching of dimensions ensures easy installation into the hydraulic part housing without additional modifications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and Application:\u003c\/h3\u003e\n\u003cp\u003eUsed for screw borehole and well pumps of the 4S QGD \/ QGD size with a power of 0.37 kW (0.5 HP):\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEuroaqua:\u003c\/strong\u003e 4S QGD 1.2-50-0.37, 4S QGD 1.8-50-0.37, 4S QGD 2.5-60-0.37.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAquatica (Leo):\u003c\/strong\u003e 4QGD 0.37 kW (777211 series models and analogues).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprut:\u003c\/strong\u003e 4S QGD 1.2-50-0.37, QGDa 0.37 kW.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOmnigena:\u003c\/strong\u003e 3 QGD, 4 QGD 0.37 kW.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOther manufacturers:\u003c\/strong\u003e Vodoley, Needle, Taifu, Rona, Foras, Werk, Kenle, Cristal, Optima and other Chinese and European submersible screw pumps if the geometric dimensions of the sleeve and screw match.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
