MPS Microsystems is working in partnership with a customer to produce hydraulic components intended to actuate the pump of an artificial heart. By selecting appropriate materials, using perfect surface finishes and complex micron-corrected geometry, this motor pump is able to reproduce the natural heart beat; the pulsatile flow created makes it possible to achieve 230 million cycles over 5 years.

Part of the assembly of components is carried out by matching and shrinking for perfect control of dimensional constraints. Glued joints (PEEK/aluminium and PEEK/steel) for this heart pump are made on plasma-prepared surfaces, guaranteeing repeatability.
