Sewage drainage system for the underground walkway of a train station

A submersible smashing cutter pump BN-series was provided for use in a sewage drainage system in the underground walkway of a train station. In the past, the pump had been frequently clogged by solid matter flowing into the sewage tank, requiring lifting of the pump and removal of solids several times each month, but after replacing the pump with the BN-series equipped with the Anti-Clogging Smashing Mechanism, the risk of clogging has significantly declined. The pump was adopted after test operations confirmed its performance, leading to labor saving in facility management and a reduction in maintenance.
