1 Description, application and working principle
1.1 Description
The BA series of pumps, with their large solids handling capacity and good wear resistance, are perfect
for pumping both clean and partially polluted liquids.
The solids handling capacity is specified on the data sheet that accompanies the pump unit.
The pumps are fitted with a half open or closed impeller and a wear plate or wear ring which can be
replaced quickly. Because few moving parts come into contact with the liquid, the pump is subject to
minimal wear.
The design includes large cleaning covers so the pump can be cleaned internally.
The design of the pump shaft seal is dependent on the application. The standard configuration includes
oil cooling of the pump shaft seal. This characteristic is indicated by a code in the type designation.
The data sheet that accompanies the pump includes all data for the pump or pump unit.
Before the pump or pump unit is connected, an assessment must always be made to determine
whether it is suitable for the intended application.
