Specifications

Tractor driven rotary lobe pump for use with shear coupling drive shafts.
Rubber lobes allow pumping of liquid manure containing solid parts with dimensions of up to 25 mm. The VL3-S is self-priming and runs both ways. Very low-mantainance through shaft-bearings placed on only one side. This enables a fast opening of the pump chamber to access to pistons and the rotary chamber (wear check, withdrawal of solid parts).
Gearing set at input rotation of tractor up to 500 rev/ min. For mobile operation mounted on a lifting support. Coupling suction- and pressure-side standard square flange 180x180 mm fits all coupling parts.
