Description/construction

Submersible pump for vertical or horizontal installation.

Hydraulic part

Multistage submersible pump with radial or semi-axial impellers in split casing design. Built-in check valve. Stainless steel parts in contact with fluid.

Electric motor

Corrosion proof single phase or three phase electric motor, rewindable with direct start possibility. With mechanical seal, self-lubricating bearings, filled with oil.

Cooling

Motor is cooled by pumped liquid. The motor may only be operated when submerged. The maximum temperature limit of the pumped liquid must not be exceeded and the minimum flow must not drop below the minimum allowable level. Vertical installation can be done with or without a cooling jacket - customer's choice. A cooling jacket is required for horizontal installation.
