<p>A pumping apparatus (1) adapted for delivering fluid against pressure. The pumping apparatus has a plurality of metering devices (3,5) adapted for metering a plurality of different fluids, and has a booster device (7) adapted for increasing the pressure of the fluids metered by the plurality of metering devices (3,5) to said high pressure, and has a damping device (9) adapted for compensating fluctuations of the fluids metered by the plurality of metering devices (3,5). Each device (3,5,7,9) has an inlet (41) and an outlet (43). The outlets of the metering devices are coupled to the inlet (41) of the booster device (7), and the outlet of the booster device (7) is coupled to the inlet of the damping device (9).</p> |
