Wilo TWI, 4-0339 VK-3/180-2,5mm², Pump Package Borehole

Description

Submersible pump for increasing and transporting water from a borehole. Integrated check valve. Supplied with installed cable and wire. Includes capacitor box for single phase. Approved for drinking water, RISE Type Approval SC0323-18.

Fully submersible, multistage pump for pumping industrial and potable water with radial or semi-axial impellers in sectional design for vertical or horizontal installation, with integrated non-return valve. Corrosion-free single-phase or three-phase motor for direct start with water-glycol filling. Hermetically molded with enamel insulation of windings, resin-impregnated and self-lubricating bearings. The motor is cooled by the pumped liquid. The device must therefore always be submerged for operation. The limits for maximum liquid temperature and minimum flow must be observed. Vertical installation is possible with or without a cooling jacket. In case of horizontal installation, a cooling jacket must always be provided.
