FIELD: engines and pumps.
SUBSTANCE: chain for pump (10) used for extrusion of disperse material comprises multiple links (30A, 30B), each provided link body (50, 54) and link support (50A) extending therefrom. Every support of the link covers the adjacent link body of said multiple links to make the set of links form a flat surface along chain fouling zone. Every body of the link comprises several plates extending therefrom. Every said plate has first and second holes connected with first holes of one adjacent link and with second holes of the other adjacent link by appropriate pin.
