The Badu 90-AK and 42-AK series are a series of pumps for salt water and very aggressive water
All Speck pumps are custom-made in AK versions, intended for salt water, where the salt content exceeds 0.5 mg / l.
The wide range of applications allows them to be used for pumping thermal waters, thermal brines, in aquariums with sea water, in installations for saline water and in installations containing various factors with a high concentration of components.
The pump corresponds to the standard version, with the exception that the intermediate lantern of the stuffing box is not mounted directly on the bearing housing of the motor, but a space has been created that separates it from the motor. In this way, leaks of pumped media and crystallizing minerals will not be able to get into the motor and its bearings. Such a design solution guarantees a significantly increased lifetime of the pump compared to the standard version.
