2. Description of the QF 5050SU pump
2.1. Appropriate use
The Quattroflow 5050SU 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 centers or plants.
Examples:
Solutions containing proteins (albumin, IgG, Clotting factors, monoclonal antibodies, enzymes,
vaccines.)
Solutions of polymers or suspensions (silicon, latex, chromatography media)
Cell suspensions (bacteria, yeast, algae, fungi, mammalian cells)
Colloidal
solutions
Suspensions of viruses or phage
Typical applications for the QF 5050SU
- Filtration technology:
To recirculate feed/retentate (e.g. 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
2.2. General description of the machine
The Quattroflow 5050SU pump is a 4-piston diaphragm pump. 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 with 6°
available.
Range of flow rate: appr. 50 - 5.000 L/hr (13 – 1321 gph), with converter
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 5050SU 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.
