<p>The technical solution relates to devices for pumping fluid media and can be used in industry, transport and the home for pumping liquids and other incompressible and compressible fluid media as well as for extracting oil from wells. The pump assembly with an electric drive consists of a housing (1), an electric drive armature (2) situated inside the housing (1), and a displacer situated in the fore end of the housing (1), wherein the electric drive armature (2) and the displacer are connected to one another. The displacer is in the form of a plunger (17). The electric drive armature (2) consists of the following, connected in series: an electric drive rear spacing block, an electric drive motion block capable of moving relative to the housing (1) in the direction of a change in the length of the motion block, and an electric drive fore spacing block. Unlike the closest prior art, at least one electric drive spacing block is in the form of a magnetostrictive spacing block (3, 5), and/or the electric drive motion block is in the form of a magnetostrictive motion block (4). The invention is intended to solve the technical problem of extending the range of existing technical equipment. The positive result of realizing the invention is that of achieving this purpose.</p> |
