Abstract
<jats:p>The application areas of axial-piston pumps are also expanding due to the widespread use of this type of equipment for working with chemically aggressive environments, various types of fuel and explosive mixtures. These types of pumps are also widely used for domestic purposes. These pumps can be used to create pipeline systems for water supply of buildings and private houses, irrigation in agriculture. Another area where piston-type pumps are widely used is the food industry. Much attention is paid to the fluid pumped by the pumps used in this area due to the differentiation of its work.
