FIELD: pumps.
SUBSTANCE: invention relates to a method for manufacturing a three-dimensional plastic impeller of a centrifugal pump, produced by means of matrices, and to an impeller manufactured thereby, wherein a mould for a curved blade and a mould for the outlet area of the impeller are used; the mould for a curved blade is configured to produced the curved blade part of each impeller blade; the mould for the outlet area of the impeller is configured to produce the back part of each blade, rim of the impeller hub, and rim of the impeller disk so that the hub rim, the disk rim, and the blades are made integrally in one moulding process.
EFFECT: creation of a three-dimensional plastic impeller for a centrifugal pump.
