Dry Installed Slurry / Manure Pump ER4-E L Specification

ER4-type centrifugal slurry / manure pump with air-cooled electric motor for stationary dry installation. Mounted on an installation frame in horizontal position for inline pumping applications.

Default suction side standard flange DIN2633 ø300. Pressure side flange square MZ-flange 180x180.

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.

The ER4-E L ist the counterpart to the ER3-E L horizontal dry installed pump. All ER4-type pumps are equipped with a special large volute to allow drive power of up to 30kW electric motors.
The default position for the pressure connector is at the vertical top position of the pump, but it can be adjusted to any angle to the left or right by turning the volute.
