Startup/shutdown of a mzr-pump

8.1

Preparing for operation

After the liquid supply system had been completed, please check once again

the operating conditions of the micro annular gear pump as according to the

following points:

−

Are the inlet and outlet tubes correctly connected?

−

Is the entire liquid supply system clean - that means free of particles, foreign

bodies, pollution or swarf?

−

Has a filter been installed on the suction side?

−

Has a sufficient amount of the right liquid been supplied?

−

The pump does not run the risk of a dry operation?

−

The entire liquid supply system has been checked for leakage?

−

Is it possible to stop the pump by an emergency switch if an unexpected

malfunction occurs at the startup?

8.2

Startup of the micro annular gear pump

Switch on the voltage supply. The micro annular gear pump can now be put

into operation by turning on the potentiometer knob or by sending a nominal

external voltage signal.

Start the filling in of the pump at low or middle speed (1000 - 3000 rpm).

Starting the pump in dry condition might lead to damage of functional

components of the pump. Therefore, it is necessary to have the pump primed

(prefilled), and also in further operation please ensure a continuous supply of

liquid. Dry running of the pump has to be avoided.
The user is liable for damages caused by, any consequence with the non-

compliance of this instruction.

8.3

Re-start after dry run

After a short dry run (it is assumed that the pump is not yet damaged), you

must ensure that the pump has cooled down to a temperature below its

maximally allowed surface temperature. The pump and the pipes must be

completely primed and filled.

Re-starting is prohibited after a longer dry run. The pump must be dismounted

to check for damage and any damaged parts replaced. The pump may only be

operated again after complete priming and filling and the restoration of the

earth.
