ER2-type centrifugal slurry / manure pump with air-cooled electric motor for stationary use as a chopper pump with mixing facility in pits and other storages.
The pump is equipped with a special valve plate to switch between the two possible operations of pumping or mixing. The agitation nozzle is pivotable 270° horizontally and vertically by 60°. Using the agitation nozzle it is possible to homogenise the slurry before pumping by stirring up floating or sinking layers.
The robust Euro-P-type impeller transforms the power of the drive into a high flow rate. The special design of the steel made impeller consists of an intake screw with hardened cutting edges to shred straw and fibres. The hefty cast-iron volute sustains even the most wearing applications and is one of the reasons for the high durability.
Basic length for pit depths up to 1.65m; all further extensions in steps of 25cm to the basic length. Special sizes are manufactured on request.
