Abstract (en)
[origin: EP0718040A1] A paint supply pump (10) delivers electrically conductive paint and has at least two pistons (16) which at as double pistons with their end faces turned towards each other and a distance apart. They operate in a common cylinder (14) to form a hollow chamber (22). The hollow chamber transfers the paint from the supply (18) to the delivery (20) points, and the two pistons are operated displaced and cyclically relative to each other. The operating surface of the cylinder is coated with an electrically non-conducting fluid (350, which is compatible with the paint, and which serves as a separating fluid between differing electrical potentials.
