Patent ID: 10781802

Abstract:
The invention relates to a pumping system (1), in particular, for transporting gaseous and/or liquid media having two parallel hydraulically operated oscillating piston pumps (2, 3) whose pistons (8) are moved by means of electromagnetic fields, whereby the electromagnetic fields are generated in field coils (10, L1, L2) by means of half-wave direct current pulse. The invention distinguishes itself by a circuit arrangement (19) that can be connected to an alternating current source having two parallel electric branches that are connected to the field coils (L1, L2) of one of the oscillating pumps (2, 3) respectively, wherein the circuit arrangement (19) is equipped in such a way that the field coils (10, L1, L2) are operated electrically out of phase so that the oscillating piston pumps (2, 3) are operated with a phase displacement of 180°. The invention further relates to a method for operating the pumping system electrically, and a circuit configuration for the pumping system and accordingly, for executing the method.
