Quattroflow QF4400SU Single Use Pump

The Quattroflow 4400SU quaternary 4-Piston-Diaphragm Pump with pump chamber made of polypropylene (Single-Use), 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.

Quattroflow® Single Use pumps are equipped with a product-wetted plastic pump chamber that can be replaced as a complete unit for disposal. This simple design feature creates a quicker production process while saving time and money because it eliminates the need for complex sterilization and cleaning validation.

The Quattroflow 4400 SU 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°available.

Range of flow rate: 50-2500 L/h (11-550 gph).
