Abstract (en)
[origin: EP0984164A2] The pump has a pump head divided into components forming the pump chambers and covers as standard units to assemble a pump in a variety of configurations in a compact structure. The membrane piston pump has at least two pump chambers (4) divided by a membrane (3) for fitting to a pump assembly with a number of pistons (1). The pump head, with the membranes and pump chambers and covers, is divided into pump head components (5a-5c) with one more than the number of chambers. The pump head components are next to each other in a row, where alternate units (5b) form the cover for the preceding component (5a) with the chamber (4) for the preceding unit (5a) when fitted in place. The membranes (3) are tensed between the pump head components (5a-5c), parallel to the stroke axes of the pistons (1), on a plane at right angles to the end side of the assembly formed by the pump heads (5a-5c).
