checked to establish whether the pump is suitable for this application.

Design

Fully submersible, multistage submersible pump with integrated non-return valve to
supply wastewater and drinking water, available as centrifugal pump in flanged bowl
construction (MSI) or progressive cavity pump (MSH).
The unit can be installed vertically or horizontally. The motor is cooled by the pumped
fluid. Therefore, the unit must always be operated immersed. The limit values for maxi-
mum fluid temperature, minimum flow rate and voltage ranges must be adhered to.
Vertical installation is possible with or without cooling shroud depending on the config-
uration. In cases of horizontal installation, a cooling shroud must always be provided.
