8 Startup/shutdown of a mzr-pump

Operating manual mzr-11507

Last update: August 2016

Technical data subject to change without prior notice!.

8.5

Problem shooting

If the pump stops operating abruptly or has difficulties with starting operation,

please undertake the following steps:

Try to liberate the micro annular gear pump:

−

by turning the potentiometer knob back and forth or by connecting an

analog voltage

−

via the control software

−

by pressing with a syringe a suitable flushing liquid (see table 9 and table 10)

through the micro annular gear pump

−

by changing the operating direction of the pump.

If these measures turn out to be ineffective, please contact the service staff of

HNP Mikrosysteme (see chapter 15) and send the pump back to the

manufacturer for inspection.

Warning

You should under no condition

try to disassemble the pump by yourself. This

may cause damage to the pump components and consequently annul your

warranty claims.

8.6

Return of the micro annular gear pump to the manufacturer

For the return of a micro annular gear pump and components that have already

been employed, please follow the instructions:

−

drain any remaining rests of the delivered liquid from the pump

−

flush the pump with an adapted solvent

−

remove the filter elements from integrated or loosely delivered filters

−

protect all openings against dust with the delivered protective plugs or

screws

−

return the pump in its original packing

The service personnel which carries out the repair should be informed about

the condition of the already used micro annular gear pump. This is done by

means of the "Declaration of media in contact with the micro annular gear

pump and its components" (see chapter 18). This form may also be

downloaded from the web site

www.hnp-mikrosysteme.de/download

The "Declaration of liquids in contact with the micro annular gear pump and

its components" must imperatively be filled in. The nature of liquid which

entered into contact with the micro annular gear pump and its components

must be specified.

In case of non-compliance, the sender will be liable for any resulting injure to

persons or any object damage.
