Service, maintenance and warranty
Maintenance of the micro annular gear pump should be carried out depending
on the delivered liquid:
for lubricating liquids after 6000 working hours, but not later than
for non-lubricating liquids, crystallizing liquids or liquids containing particles ,
If during the first inspection the pump shows a particularly strong wearout, the
maintenance intervals should be readapted to the changing operating
parameters.
In order to prevent a strong wearout of the pump, the pump should be shut
down properly after every application as described in the chapter 7.3.
A supplementary flushing procedure with a neutral flushing liquid
(see chapter 7.3) also slows down the wearout process of the pump.
It is not allowed to open or dismantle the micro annular gear pumps. The
!
warranty extincts with the expiry of the legal warranty period or with the
opening of the pump. Furthermore HNP Mikrosysteme cannot give any
warranty of exchange for parts whose damage result from incorrect use.
For service and maintenance please return your micro annular gear pump to
!
HNP Mikrosysteme. You will find the address on the cover of the present
operating manual.
The declaration of media (liquids) having had contact with the micro annular
!
gear pump and components must imperatively be completed. The nature of
media (liquids) must be specified. In case of non-compliance the sender will be
liable for any resulting injure to persons or any object damage.
Sealing elements, rotors and shaft are parts that undergo wear and will be
!
replaced by HNP Mikrosysteme GmbH during maintenance depending on their
degree of wear.
Last update: January 2016
15 months after the initial operation
after 4000 working hours but not later than 12 months after the initial
operation. If during the first inspection no substantial wearout of the pump
is observed, the following inspection under the same working conditions
should be performed after 6000 working hours, yet not later than
15 months following to the last inspection.
