3. Description of the Quattroflow QF5050 pump
3.1 Application and range of utilization of the Quattroflow QF5050 pump
The Quattroflow QF5050 is a 4-piston Diaphragm pump, which 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 centres or plants.
Typical examples of these fluids:
•
Solutions containing proteins (albumin, IgG, Clotting factors, monoclonal antibodies, enzymes,
vaccines.)
•
Solutions of polymers or suspensions (silicones, latex, chromatography media)
•
Cell suspensions (bacteria, yeast, algae, fungi, mammalian cells)
•
colloidal solutions
•
Suspensions of viruses or phages
•
Dairy products
•
Gelatin
•
Supplements and ingredients for cosmetic and food.
3.2 Typical process steps in which the Quattroflow QF5050 pump is used
Filtration technology
•
To recirculate feed/retentate (i.e. membrane cassettes, hollow fibre, 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
3.3 Discription of the working princaple Quattroflow QF5050
The Quattroflow QF5050 pump is a 4-piston diaphragm pump. The 4 segments of the pump diaphragm
oscillate back and forth. This alternate movement is created by a nutation disc that is arranged on a ball
bearing. The ball bearing sits on an eccentric shaft. The nutation disc does not turn!
The stroke of the pistons is determined by the angle of the 6° eccenter shaft.
Range of flow rate: appr. 50 -5.000 L/hr
The drive = motor + control needs to be choosen according to application.
(MDX61B0030-54-00, not in scope of supply)
Please note:
The direction of flow can be adjusted by turning the pump chamber in 90° steps.
The Quattroflow QF5050 is self-priming and can run dry. Inside the pump chamber there are no rotating
parts that might cause heating up of the product or shed particles.
The pump-motor unit is mounted on a stainless steel base plate.
