1. Scope of delivery
Be careful when unpacking the metering pump and
order-related accessories in order not to miss small
parts. Compare the scope of delivery to the delivery
not. If there are any discrepancies, try to find out
the reason.
For the transportation of the metering pumps, no
special fittings are required. It is, however,
advisable to choose a transportation method, which
is appropriate for the weight of the metering pumps
(e.g. wagon). During transportation without oil, the
metering pump should be lying. Otherwise it must
be tightened to the transportation device.
