FIELD: metallurgy.
SUBSTANCE: there is obtained rod body and head in the form of all-metal structure by forging and proceeds in two stages. Head allows external clamp and "area for key". At the first stage it is received initial semi-finished product with reinforced part and formed "area for key". At the second stage it is implemented final formation of external clamp of head. The second stage is implemented at least at three sequential conversions at least in three final impressions. At the first conversion in the first impression there is introduced metallic technological ring into area of formed clamp. In the following impressions it is implemented final clamping of semi-finished product.
EFFECT: increasing of bearing capacity of pump rod.
