A magnetic reciprocating pump for pumping fluids, i.e. gases or liquids, with high pressures and at high temperatures is provided.Magnetic pumps The pump has a piston freely movable in a tube of non-magnetic material and provided with recesses for the fluid to be pumped. A ball valve is provided in the piston and in one end of the non-magnetic tube. The drive force on the piston is transmitted by permanent ring magnets arranged outside of the non-magnetic tube, said ring magnets being reciprocated by a thrust rod driven by an electric motor. The balls of the valves are of steel and for sealing the high pressure system metal rings are provided.Self-priming pumps Connecting rods connect the peripheral body of the pump containing the magnets to the peripheral body of a magnetic coupling the core piece of which is arranged freely movable in a sealingly closed guide tube and is made up of axially magnetized permanent ring magnets. The magnets are secured to an arbor connected to the thrust rod. The peripheral body of the magnetic coupling has the same number of fixedly arranged, axially magnetized ring magnets as the core piece.
