Blood pump unit for use in extracorporeal circulation

Medical Electronics & Biological Engineering, 1964
A novel type of constant speed reciprocating pump with a positive displacement action is described. The pump consists of a pumping chamber with non-return valves to prevent back-flow, and a smoothing chamber where the pressure and flow pulsations are reduced in amplitude. The pump runs at 95 strokes/min and 190 strokes/min.

Unit Pump System UPS

2010
Das Unit Pump System (UPS) wird bei Nkw und Grosmotoren eingesetzt. Die Arbeitsweise der Unit Pump (UP) entspricht der des Unit Injectors (UI) fur Nkw. Im Gegensatz zum UI sind bei der UP jedoch Einspritzduse und Injektor raumlich getrennt und uber eine kurze Leitung miteinander verbunden. Das Unit Pump System wird daher auch Pumpe-Leitung-Duse genannt.
