Pump head for hot gas etc. pump - has covered chambers, contg. e.g. screw connections for pipes extending from heating jacket

摘要

The pump head (1) has known chambers (12) to accommodate connection elements (22) for pipes (2), projecting from the heating jacket (21). The intake and the delivery duct (13) extend to the chambers. The chambers are formed by recesses (12a) in the pump head with a removable cover (11). There are devices for heat- conductive clamping of the connection element section (22a) next to the heating jacket. The clamping devices are formed by a reduced-size passage (16) between the chamber wall and cover. USE/ADVANTAGE - For analytical purposes,maintaining original temp.from the source the measuring point,without heat losses.
