Pierburg Pump Technology has mapped out a variety of approaches with a view to ensuring dependable lubrication and reliable regulation of the oil supply system under all operating conditions. The aim is to be able to supply pumps that address all the functional requirements while maintaining maximum efficiency and achieving the slightest possible losses. Pierburg Pump Technology’s design department has highly advanced design and simulation tools as well as extensive expertise in the structural analysis of finite elements (static, modal, spectral and fatigue), computer fluid flow dynamics (CFD) and multi-body simulation. Multi-body analysis were introduced to obtain precise information on the factors affecting moving components. The advantage of vane pumps is that they can be simply and continuously controlled over a large adjustment range with constant efficiency. What’s more, they can be positioned both on the crankshaft and in the oil pan. The solution chosen by Pierburg Pump Technology permits the use of various passive and active forms of control.
