We consider magnetically active elastomer as a potentially applicable material for manufacturing a working channel of a magnetic pump unit. During the study, the samples were exposed to a magnetic field, a temperature field, and their combination to assess the change in the elastic-strength properties of the final material. For the preparation of samples, high permeability magnetic fillers of various sizes were used in the concentration range of 50–70%. Samples were made with an isotropic and an anisotropic structure. Studies have shown that when using a filler with a relatively coarse fraction, the material has more stable dynamic and mechanical characteristics: the tensile strength of the sample increases by an average of 38%. With the combined effect of magnetic and temperature fields on the material, its elasticity and strength increase by an average of 30% in comparison with the material without external influence. Based on the results obtained, the composition and structural organization of the material, which has the best complex of elastic strength characteristics, has been substantiated. For the manufacture of a pumping unit tube, it is preferable to use an isotropic magnetoactive elastomer with a coarser filler content of about 60%.

This paper is devoted to improvement of application of a peristaltic transport of heavy high-viscosity materials using magnetically active material. The main problems that arise when pumping these substances are associated with their low mobility and high shear stress. In various countries of the world peristaltic pumps are increasingly used for this purpose. A fundamentally new approach to transportation of liquid and viscous media consists in using magnetic pumps. Heavy oil and highly concentrated slurry tailings mineral resources are non-conductive materials, and as a result, require the active inducement effect on the portion of the material of the working chamber of the direct channel.
