2. Description of the QF 1200S pump
2.1. Appropriate use
The Quattroflow 1200S 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
Dairy
products
Gelatine
Supplements and ingredients for cosmetic and food
Typical applications for the QF 1200S
- 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 1200S 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 5°
and 3° available. The range of flow rates can be modified by changing the eccentric shafts. For the
compact models with integrated controller please see chapter 2.4.
Range of flow rate:
5° eccentric shaft: approximate 20 -1200 L/hr (40 – 1200 L/hr for pumps with controller)
3° eccentric shaft: approximate 10 - 800 L/hr (20 – 800 L/hr for pumps with controller)
In gallon:
5° eccentric shaft: approximate 5.3 - 317 gph (10.6 - 317 gph for pumps with controller)
3° eccentric shaft: approximate 2.64 – 211 gph (5.3 - 211 for pumps with controller)
The drive = motor + control needs to be chosen according to application.
