Quattroflow QF1200 Series 4-Piston Diaphragm Pump with Single-Use Chambers

The Quattroflow QF1200 Series 4-Piston Diaphragm Pump with Single-Use Chambers is mainly used to pump water-like fluids that are typically handled in research, pilot plant, or production facilities of the pharmaceutical, biotech, food or cosmetic research centers or plants.

The four segments of the pump diaphragm oscillate back and forth. This alternate movement is created by a connector plate that is arranged on a ball bearing. The ball bearing sits on an eccentric shaft. The connector plate does not turn.

The stroke of the pistons is determined by the angle of the eccenter. There are eccentric shafts at 3 and 5° available. The range of flow rates can be modified by changing the eccentric shafts.

Typical applications include:

• Filtration technology:
  • To recirculate feed/retentate (e.g. membrane cassettes, hollow fiber, spiral wound, ceramic elements)
  • Feed pump for filter cartridges or plate and frame depth filters
• Chromatography:
  • Packing of chromatography columns
  • Feed pump to mix gradients
• Feed pump for centrifuges or separators
• Feed pump for homogenizers
• Feed pump for filling machines
