Abstract
The invention relates to a piston metering pump (1) for aggressive liquids, notably liquid metals such as lead or aluminium, which comprises a pump housing with a pump base. The pump base has at least one valve which communicates with several channels situated in the pump base (10). The pump base (10) further comprises several disk-like segments (20, 30, 40) each presenting grooves and holes (21, 22, 31, 41) which form the channels.
