Liquid supply
The liquid inlet is marked with the letter »S«, the liquid outlet connection with
the letter »D«. An arrow indicates the inherent turning direction of the shaft.
For protection against penetrating dust particles and contamination, sealing
plugs are inserted into the threads. The sealing plugs have to be removed
before the assembly of the fluidic connectors. Please reseal the threads with the
cleaned sealing plugs when the fluidic connectors are disassembled.
The assembled fluid connectors have to be checked immediately after bringing
the pump into operation. This is also true for service in a half-yearly cycle on
tightness and leakage.
