Definitions

  • Pumps such as piston pumps, diaphragm pumps, peristaltic pumps and the like, deliver intermittently, which is problematic for many delivery tasks.
  • Devices are known for damping the shocks and thus for equalizing the volume flow, in which the pressure shocks of the pump are compensated by a spring-loaded membrane.
  • the main disadvantage is the cleaning and maintenance of the moving parts that have such devices. Furthermore, such devices do not automatically drain themselves when the pump is switched off.
  • the tube 1 In the area of the enclosed air volume 11, the tube 1, if not made of a transparent material, can have a window 12 with a pressure scale.
  • the pipe cross-section between the inlet opening and the outlet opening should be chosen smaller than the cross-section of the remaining pipe.
