FIELD: engines and pumps.
SUBSTANCE: getter pump comprises a body (21, 21') in the form of a body of revolution with a rotation axis (24), and a plurality of gas-absorbing cartridges (22, 23) mounted inside the body (21, 21'). Each cartridge (22, 23) comprises a rectilinear central base (221, 231) and the spatially distanced getter elements installed on the rectilinear central base (221, 231). A plane containing the rectilinear central base (221, 231) and parallel to rotation axis (24) defines the orientation plane of the getter cartridge, and the plane orthogonal to the rotation axis (24) and crossing the middle of the rectilinear central base (221, 231) determines the positioning plane (222, 232) of the gas-absorbing cartridge. Angles (α, α') between the positioning planes (222, 232) and the rectilinear central bases (221, 231) do not exceed 30°.
EFFECT: increased pumping rate of the getter pump.
