3. Description of the Quattroflow QF4400 pump
3.1 Application and range of utilization of the Quattroflow QF4400 pump
The Quattroflow QF4400 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 QF4400 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 QF4400
The Quattroflow QF4400 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. 100 -5.000 L/hr
The drive = motor + control needs to be choosen according to application.
Please note:
The direction of flow can be adjusted by turning the pump chamber in 90° steps.
The Quattroflow QF4400 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. In case that the pump will not be mounted on
the base plate but in a frame or any other base measures have to be taken that there will be a proper
alignment of the motor and the pump.
