DNE microtechnology and 2E mechatronic have developed a new pump system for conveying a wide variety of fluids. It combines all the benefits of different pumps, such as diaphragm, piston injection and peristaltic pumps. The aim was to develop a reliable pump with an exchangeable fluid impelling part which, due to its modular construction, is capable of conveying a variety of fluids in parallel. The new pump system meets these demands.
Basic model with two to five flow channel
The basic pump has a maximum of five independent flow channels. This guarantees that in each channel a defined volume can be conveyed independently of pressure fluctuations in neighboring channels.
Extendable to a maximum of 10 channels
The modular construction makes it possible to increase the number of channels to a maximum of 10. Tubes with different internal diameters are available which can be flexibly inserted into each channel.
Wide flow volume range
The flow rate of the pump can be varied due to its modular construction. This can be achieved by varying the gears in the motor or by using tubes with different internal diameters. Flow volumes can thus range from a few microliters to several milliliters per minute.
Disposable fluidic part
The inexpensive fluid driving part of the pump which comes into contact with the conveyed material can be exchanged by means of a simple coupling action. The drive unit comprising a drive motor, gear box, housing and actuator can thus be utilized several times. This contributes to a reduction in operating costs and protection of the environment.
Application
The pump was developed for use in laboratories or for analytic purposes. Cross-contamination can be avoided by regularly exchanging the fluidic part. Thanks to its multiple possibilities the pump can also be used in other areas.
