PURPOSE: To reduce technical complication of manufacture, the number of connection points, facilitate washing of an outer surface, and improve strength by arranging chambers in a wobble plate pump other chan pump chambers, which are connected to a suction or compression area of a pump, and through which fluid flows continuously and in a regulated manner.

CONSTITUTION: A casing has integrated channels 14, 15 through which chambers 12, 13 are connected to a suction and compression regions of a wobble plate pump. This type of wobble plate pump is particularly suited for usage requiring easy washing of the pump.
