Multistage submersible pump in tie strap version (QSI) or as a helicoidal rotor pump (QSH) for vertical or horizontal installation

Fully submersible, multistage submersible pump as a progressive cavity pump with integrated non-return valve for pumping process water. A corrosion-free, encapsulated permanent magnet motor with water-glycol filling and integrated frequency converter is used as the drive. The permanent magnet motor is hermetically sealed with enamel-insulated windings, resin-impregnated and with self-lubricating bearings. The integrated frequency converter allows operation using a direct current source. The OPTI-QS pump is thus especially suitable for solar power operation. In applications with solar modules, the integrated software algorithm MPPT (“Maximum Power Point Tracking”) allows the available power to be matched in order to maximise the pumped volume flow (dynamic MPPT). The unit can be installed in a vertical or horizontal position. The motor is cooled by the pumped fluid. Therefore, the unit must always be operated immersed. The limit values for maximum fluid temperature, minimum flow velocity and voltage ranges must be adhered to. Vertical installation is possible, depending on the design with or without cooling shroud. In cases of horizontal installation, a cooling shroud must always be provided.
