Impellers are referred to as a core component of turbomachinery. The use of impellers in various applications is considered an integral part of the industry. So, increased performance and the optimization of impellers have been the center of attention of a lot of studies. In this regard, studies have been focused on the improvement of the efficiency of rotary machines through aerodynamic optimization, using high-performance materials and suitable manufacturing processes. As such, the use of polymers and polymer composites due to their lower weight when compared to metals has been the focus of studies. On the other hand, methods of the manufacturing process for polymer and polymer composite impellers such as conventional impeller manufacturing, injection molding and additive manufacturing can offer higher economic efficiency than similar metal parts. In this study, polymeric and polymer composites impellers are discussed and conclusions are drawn according to the manufacturing methods. Studies have shown promising results for the replacement of polymers and polymer composites instead of metals with respect to a suitable temperature range. In general, polymers showed a good ability to fabricate the impellers, however in more difficult working conditions considering the need for a substance with higher physical and mechanical properties necessitates the use of composite polymers. However, in some applications, the use of these materials needs further research and development.

Pipes are manufactured primarily through the extrusion process. One of the material extrusion processes in recent digital manufacturing is additive manufacturing’s fusion deposition modeling. Pipes are made from various materials such as metal and plastic/polymers, and the main challenge has been in selecting the pipe material for the customized application. For the creation of water-passing tubes, this research has chosen appropriate carbon-reinforced polymers that can be used with filament made of polyether ether ketone (PEEK) and polyethylene terephthalate glycol (PETG). For this goal, the analytical hierarchy process, also known as the AHP, is used to choose the best material based on factors such as cost, temperature resistance, printing speed, and mechanical properties of the material. The results revealed that PEEK-CF is a better material for the customized impeller application than PETG-CF. The PEEK-CF obtains the higher priority value of 0.6363, and the PETG-CF obtains 0.2791. This decision-making technique can be used to select other comparable customized applications.

“…Designing the impeller with winglets allows increasing the head and efficiency of torqueflow pumps [13,14]. However, it should be noted that in these papers, experiments were carried out during pumping pure water, while these modifications may lead to deterioration of the pump's ability of contaminated liq uids transporting [15,16].…”

Purpose. Evaluation of the effect of changing the width of the impeller blades on the characteristics of a torque-flow pump. Searching for the optimal blade extension into the free chamber of the pump. A torque-flow pump of the “Turo” type SVN 500/32 was chosen as the subject of the research work. Methodology. A number of numerical experiments were conducted to determine the flow structure in the flowing part of a torque-flow pump. The width of the impeller blade was chosen as a variable. Numerical experiments were carried out using the ANSYS CFX software package. The integral parameters of the researched pump were determined in order to build the integral characteristics. Findings. The structure of the general flow and toroidal vortex was studied and analyzed in the torque-flow pump. A flow model was built in a torque-flow pumps with basic and modernized design. A relationship between the parameters of the pump and the change in the impeller blade width was found. The width of the impeller blade was changed in the range from min = -20 to max = +100 mm. Originality. The paper researched the effect of additional hydraulic losses caused by the mismatch between the center of the toroidal vortex and the edges of the impeller blades on the integral characteristics of the torque-flow pump. Practical value. A significant increase in the operating parameters of the “Turo” type torque-flow pump was achieved with the help of modernization of the impeller design. This allows expanding the range of the pump’s operation. At the same time, it is not required to replace such expensive elements as the pump casing.
