Abstract

The present invention relates to a system (100) for transporting a liquid from a reservoir (600) containing the liquid. The system comprises •a first and second conduit (400, 500), each with a lower end (402, 502) and an upper end (404, 504), •a first pump (200), with an inlet end (201) and an outlet end (202): •wherein one of the lower end (402) of the first conduit (400) or the upper end (504) of the second conduit (500) is connected to a second pump (300): —wherein a height difference between the first and second pump (200, 300) is within a maximum pumping height of a lower pump of the first and second pump (200, 300). Further, the present invention relates to a method for operating a plurality of pumps in a system (100).

Dependent claims

A system for transporting a liquid from a reservoir containing the liquid, to a level above a liquid surface in the reservoir, the system comprising:

an upper coil pump, with an inlet end and an outlet end;
a lower coil pump with an inlet end and an outlet end;
wherein the inlet end of the upper coil pump is fluidly coupled to the outlet end of the lower coil pump;
wherein the inlet end of the lower coil pump is fluidly coupled to an outlet from the reservoir;
wherein the upper coil pump is arranged at a higher level than the lower coil pump;
and
a control system coupled to a sensor, the sensor monitoring the liquid level in the reservoir, the control system being coupled to the coil pumps to control activation and deactivation of the coil pumps depending on the liquid level in the reservoir.
