The invention relates to a pump assembly for pumping brake fluid into a hydraulic slip-controlled vehicle brake system. To achieve a simple, compact construction of the pump assembly, the invention proposes embodying the pump assembly with an electromagnet which has a permanent magnet and is driven into an oscillating motion by being supplied with an alternating voltage; a moving part of the electromagnet is solidly connected to a tappet, both of whose ends form pistons of two piston pumps.
