Abstract
A pump with positive displacement for pumping and entrainment of a fluid in piping (3), includes a cylinder (6) which contains deformable pumping bellows (12) which separate two pumping chambers, a driver (34, 29) which is associated with the pumping unit (12) and has an actuator unit (29) inside the cylinder (6) which is connected to the pumping unit (12), and coils (34) for transmission of drive energy to the actuator (29) from outside the cylinder (6), and a manifold (2) with vortex fluid diodes, which is designed to control the global direction of pumping and flow of the fluid in the piping (3).
