Operating instructions Concept PDG 2906 peristaltic dosing pump
21 / 44
Tube connection
WARNING! Escape of hazardous liquid at high pressure
Kinking the tube generates high pressure that can cause the tube to rupture and
the pumped medium to escape.
Take care that tubes are installed in the proper manner, and observe the
maximum bending radius.
Please note the following points:
•
Tube diameter and tube length should be selected so that the total pressure within the
tube system (pump tube and supply tube) and, if applicable, the installation does not
exceed the maximum permissible value (see “Technical specifications” section).
•
Connect tubes to the corresponding connections in the proper manner.
•
Connect the suction line and pressure line correctly. Observe the markings
and
on
the tube kit.
