Wilo-Sub TWU 4-0418-C EM submersible pump
Sub TWU4-0418-C fully submersible submersible pump (1~230 V, 50 Hz)
Introducing a multi-stage submersible pump from Wilo - Sub TWU4-0418-C. The unit is fully submerged, equipped with radial or semi-axial impellers of segmented design, which allow both vertical and horizontal mounting (a cooling jacket is required for horizontal mounting). With built-in backflow protection, the pump guarantees reliable pumping of water from deep wells
The motor, which is corrosion-resistant, operates on AC or three-phase induction current and is designed for direct starting (DOL). Filled with a mixture of water and glycol, hermetically sealed, with enamel windings, impregnated with resin and equipped with self-lubricating bearings, it is cooled by the flowing medium. The unit must always be submerged to ensure proper cooling of the motor
Purpose
The pump is designed for pumping water from deep wells with a maximum immersion depth of up to 200 m and a maximum sand content of 50 g/m³
