Final inspection
After production, the micropumps have to pass a final inspection.
They are tested concerning the maximum flow
and back pressure.
Measurement conditions:
Pumping media: distilled water
Temperature: room temperature 23°C
Controller: extended box mp-x
Electrical Input: amplitude of 250 Vpp and SRS-Signal with 100 Hz (for liquids) and 300 Hz (for gases)
Measurements with sensors:
volume flow
range:
0 - 10 ml/min
accuracy: +/- 1% FS (=0.1 ml/min)
pressure
range:
0
–
1 bar
accuracy: +/- 0.35% (= 3.5 mbar)
Other application specific outgoing inspections can be offered for all pumps upon customer demand.
In order to guarantee proper function of the delivered goods and exclude transportation damages please check the
incoming devices according to specifications after receipt.
Based on these results a replacement can be carried out within 14 days after delivery free of costs.
Operating the micropump
In this chapter the operation of the micropump during the evaluation is described. This chapter provides information
on the proper connection of the pump with tubing and electrical cables and typical driving parameters to start the
evaluation.
Please connect suitable tubes to the inlet and outlet. The tubing should have an inner diameter of ~1.3 mm for the
mp6, mp6-AIR, mp6-AIR-HP and mp6-pi and ~1.2 mm for the mp6-pp. The micropump has to be connected to a
suitable controller as described in the next sections.
The electrical connection of the micropumps flexible connector is described in the corresponding chapter. The flexible
connector will be attached to the desired controller.
On both type pumps, traces of surface corrosion may appear on the electrical connector. This corrosion only causes
a visual influence, negative effects on the pump performance could not be detected based on performance tests
