FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to pump systems, namely to a mechanism for connection of a delivery system unit with a downstream pipeline. Delivery unit for use in connection of pump in horizontal pump system with downstream pipeline (116) comprises delivery head (118) with internal channel (126), bushing (120) for flange, made with possibility of sliding interaction with delivery head (118), movable flange (122) and end flange (124). Bushing (120) for flange comprises proximal part (130), distal part (132) and shoulder (134) separating proximal part (130) from distal part (132). Proximal part (130) is located in channel (126) with the possibility of sliding.
EFFECT: invention is aimed at reducing wear by providing the possibility of rotation and axial movement of bushing (120) in fixed delivery head (118).
