Indication of the turning direction and fluidic connections on the front of the micro annular gear pump
The pump head has two inner threads for the connection of tube fittings. The
pump head is available either in a version for lateral connections with 3/8” NPT
fittings.
Sealing plugs are inserted into the holes for the fluidic connections as
protection against contamination during delivery. The sealing plugs have to be
removed before assembly of the fluidic connectors. If the fluidic connectors are
disassembled, please re-seal the threads with the cleaned sealing plugs as
protection against particles.
