Material code
1.2 Proper use
Information on proper use of the pumps is provided in
the technical data sheet.
The execution of the pump is precisely matched to the
operating conditions (see order data sheet).
Any subsequent modification to the
medium or the operating data must be
discussed and agreed with the manufacturer,
otherwise our liability for any faults that may arise will
be void.
1.3 Performance data
The exact performance data applicable to the pump
can be taken from the order data sheet and/or
acceptance test report, and are engraved on the name
plate.
The pressure data indicated there apply only to
approximated static pressure load. In the case of
dynamic alternating pressure load, consult the
manufacturer.
1.4 Warranty
Our warranty for shortcomings in the supply is laid
down in our delivery conditions. No liability will be
undertaken for damages caused by non–compliance
with the operating instructions and service conditions.
If at any later date the operating conditions change (e.g.
different fluid conveyed, speed, viscosity, temperature
or supply conditions), it must be checked by us from
case to case and confirmed, if necessary, that the pump
is suited for those purposes. Where no special
agreements were made, pumps supplied by us may,
during the warranty period, only be opened or varied by
us or our authorized contract service workshops;
otherwise our liability for any defects will cease.
1.5 Testing
Prior to leaving our factory, all pumps are subjected to a
thorough test run and performance test on the test
stand. Only properly operating pumps, achieving the
performance assured by us, leave the factory.
Thus, compliance with the following operating
instructions ensures fault–free operation and full
delivery.
1.6 Availability
As a matter of principle, we recommend stocking
replacement pumps and withdrawable units (hydraulic
action system) where the supplied pumps are a
decisive factor in maintaining a production or delivery
process. In this way downtimes can be avoided, or
reduced to a minimum.
