Wilo TWI, 4-0223-C VK-3/80, Pump Package Borehole

Description

Submersible pump for increasing and transporting water from a borehole. Integrated check valve. Supplied with installed cable and wire. Incl. capacity box for single phase. Approved for drinking water, RISE type approval SC0323-18.

Fully submersible, multi-stage pump for pumping industrial and potable water with radial or semi-axial impellers in sectional construction 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 sealed with enamel insulation of windings, resin impregnated and self-lubricating bearings. The motor is cooled by the pumped fluid. Therefore, the unit must always be submerged for operation. The limited values for maximum fluid temperature and minimum flow rate must be observed. Vertical installation is possible with or without a cooling jacket. For horizontal installation, a cooling jacket must always be included.
