Wilo-Sub TWU 4-0414-C EM submersible pump
Sub TWU4-0414-C total submersible submersible pump (1~230 V, 50 Hz)
Introducing the Wilo Sub TWU4-0414-C multi-stage submersible pump, designed for total submersion and pumping water from deep wells. The unit is equipped with radial or semi-axial impellers of segmented design, which allow vertical or horizontal mounting - an additional cooling jacket is required for horizontal mounting. The pump has built-in backflow protection, and its AC or three-phase induction motor, which is immune to current when blocked, has been made with direct starting (DOL) technology. The motor, filled with a mixture of water and glycol, is hermetically sealed, with enamel windings, impregnated with resin and equipped with self-lubricating bearings - cooling is provided by the pumped medium, so the pump must always be submerged
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
