Abstract

In a worm pump, for charging pneumatically transportable bulk material into a conveyor duct, of the kind having a worm mounted on each side of a delivery housing 2 and a nonreturn valve 3 in the delivery housing, the delivery housing is constructed in the form of a spiral, as viewed in the pump cross-section. This expedient helps to reduce the friction losses which occur when bulk material is discharged from the delivery housing, and in consequence helps to reduce the energy requirements of worm pumps with twin worms. Air is supplied to the conveyor duct via air permeable walls 7, 8.
