Wilo-Sub TWU 4-0414-C DM submersible pump

Sub TWU4-0414-C total submersible submersible pump (3~400 V, 50 Hz)

Introducing a multi-stage submersible pump from Wilo, designed for total submersion and pumping water from deep wells. The device is characterized by a segmented design of radial or semi-axial impellers, which allow both vertical and horizontal mounting (a cooling jacket is required for horizontal mounting). The pump is equipped with built-in backflow protection and a corrosion-resistant, submersible AC three-phase motor for direct starting (DOL)

The motor is filled with a mixture of water and glycol, hermetically sealed, with enamel windings, impregnated with resin and equipped with self-lubricating bearings, cooled directly by the flowing medium - so the unit must always be submerged

Purpose

The pump is dedicated to pumping water from deep wells with a maximum immersion depth of up to 200 m and a maximum sand content of 50 g/m³

Scope of delivery

• Hydraulics together with the motor ready for installation
• Power cable with approval for drinking water
• AC version with junction box with capacitor, thermal motor protection and on/off switch
• Installation and operating instructions
