Submersible pump as centrifugal pump in sectional construction (QSI) or as progressive cavity pump (QSH) for vertical or horizontal installation.

Hydraulics

Multistage submersible motor centrifugal pump (QSI) with radial impellers in sectional construction or progressive cavity pump (QSH) with helical rotor inside a twin-helix rubber stator. Integrated non-return valve. All parts that come in contact with the fluid are made of corrosion-free materials.

Motor

Single-phase current permanent magnet motor. Sealed and hermetically cast motor, resin-impregnated, with enamel-insulated winding, self-lubricating bearing, with water-glycol filling.

Frequency converter

Hermetically sealed frequency converter for direct operation using direct current sources. The integrated software algorithm MPPT (“Maximum Power Point Tracking”) enables the available power to be matched in order to maximise the pumped volume flow (dynamic MPPT).

Safety functions:

• Overvoltage protection
• Excess current protection
• Dry-running protection (via integrated sensor)
• Temperature monitoring

Cooling

The motor is cooled by the pumped fluid. The motor must always be immersed when operated. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. Horizontal installation must be performed in conjunction with a cooling jacket.
