3 Description
The pump is a machine for pumping fluids that is particularly insensitive to permanent stress and
contaminations in the fluid. Designed as a piston diaphragm pump, the pump delivers the fluid in self-
enclosed volumes.
The diaphragm consists of 4 segments. A connecting ring that is moved back and forth from its centre
position by an eccentric shaft activates the segments and creates the stroke movement. An electric motor
drives the eccentric shaft.
The motor speed determines the pump performance. The direction of flow of the pump is independent of the
direction of rotation of the motor.
The pump is self-priming and dry run-protected. The pump head contains no rotating parts that rub together.
As a displacement pump, the pump already builds up the required pressure at low speeds.
The single-use pump chambers are intended for single use.
3.1
Water-like fluids
The pump only delivers water-like fluids such as:
•
Solutions containing protein (albumin, IgG, clotting factors, monoclonal antibodies, enzymes, vaccines)
•
Solutions or suspensions of polymers
•
Cell suspensions (bacteria, yeast, algae, fungi, mammalian cells)
•
Colloidal solutions
•
Virus suspensions, phage suspensions

Labelling
The type label is affixed to the housing or the base plate.
The serial number is affixed to the top.
