FUEL PUMP

摘要

Inlets (8) and outlets (24) supply a pumping chamber (5) in a pump casing (7). A pumping wheel (3) in the pumping chamber fastens on a rotary drive shaft (2) that rotates on bearings in the pump casing. Pumping chamber surfaces adjacent to surfaces on the pumping wheel and pumping wheel surfaces adjacent to surfaces on the pumping chamber have a thinner, harder coating.
