WILO Wilo Submersible Motor Pump Sub TWU4-0204-DM-D-QC-GT, Rp11/4, 0.25kW – 6091415

Submersible, multi-stage, close-coupled submersible motor pump with radial or semi-axial impellers in sectional design for vertical or horizontal installation, with integrated non-return valve. Corrosion-resistant three-phase motor for direct start with water-glycol filling. Hermetically encapsulated with enamel-insulated winding, resin-impregnated and self-lubricating bearings. The motor is cooled by the pumped medium. Therefore, horizontal installation must be carried out in conjunction with a cooling jacket. For pumping water for geothermal applications with a maximum immersion depth of 200 m and a max. sand content of 50 g/m³. The QC version is equipped with a quick-connection cable for easy and quick replacement of the power cable.Operating dataPumped medium: WaterMax. head: 26.71 mUnitMinimum Efficiency Index (MEI): 0.7Discharge-side pipe connection: Rp 1¼Maximum operating pressure: 40 barMax. sand content: 50 g/m³Motor protection class: IP68Max. immersion depth: 200 mMin. medium temperature: 3 °CMax. medium temperature: 40 °CNet weight approx.: 8.6 kgMax. diameter: 98 mmMotor dataMotor design: Submersible motorMains connection: 3~400 V, 50 HzMotor nominal power: 250 WNominal speed: 2865 rpmNominal current: 0.67 AStarting type: Direct (DOL)Max. switching frequency: 20 Motor diameter: 95.25 mmMin. flow velocity at the motor: 0.08 m/sCableConnection cable length: 1.5 mCable cross-section: 3x1.5 + 1G1.5 mm²MaterialsPump housing: Stainless steelMotor housing: Stainless steelShaft: Stainless steelImpeller: PPEOrdering informationNet weight approx.: 8.6 kgMake: WiloPart number: 6091415
