Submersible drainage pumps for abrasive drainage water - Bau-Box R


Every construction site places different demands on the dewatering pump, which is why particularly clever solutions are required for difficult pumped media. In order to enable a strong pumping action, especially with muddy and greasy media, the pump in the new Bau-Box R is equipped with a stainless steel agitator head. The rotation of the agitator head results in improved flowability of the pumped medium. Problematic mixtures of dirty water, sand or bentonite are pumped off without any problems due to the turbulence and the special suction behavior of the HBPR construction pump. The compact powerhouse is also technically convincing, as it has all the technical features of the construction box pump.


Stationary or transportable. Design with float circuit as automatic dirty water pump with water level-dependent operating control.
