ABSTRACT:
The pump has several cylinders which are arranged in a row narrowly adjacent to one another and which accommodate the stroke working spaces of plungers or pistons. The stroke work of the pistons is hydraulically transmitted to diaphragms which close off pump working spaces inside of diaphragm working spaces in the direction of the cylinders. Because of the arrangement of the diaphragm working spaces or of the pump working spaces on different sides of the cylinder block, diaphragms or diaphragm working spaces may be arranged which have cross-sections that are large in comparison to the distance of the cylinders from one another.
