The performance range of the Dulco flex peristaltic metering pumps has been extended to a maximum performance of up to 65 l/h at up to 5 bar backpressure. A special variant has been developed for dosing small dosing quantities. This peristaltic metering pump of the Dulcoflex control – DFXa series is available in the following three versions: For metering
- 6 ml/h to 18 l/h (5 bar),
- 10 ml/h to 30 l/h (7 bar) and
- 22 ml/h to 65 l/h (5 bar).
The new 18 l/h variant is suitable when a few ml/h should be dosed with high precision.
At maximum feed rate, the rotor speed is 100 rpm for all types. Due to this moderate speed, the tube is not compressed that often which leads to longer intervals. The wide control range of 1:3,000 allows very slow speeds, and because of this, the service life can be extended even further. Suitable tube materials, and a pump design optimized for the application, ensure long service intervals; the number of interruptions in production or the process, due to tube changes, is therefore significantly lower.
A quick and uncomplicated tube change, completely without tools, is guaranteed thanks to a combination of patented liquid end and tube changing process, programmed in the user interface. The display provides the fitter with precise instructions about the steps to be completed when replacing the hose, preventing operating errors and saving costs.
The peristaltic metering pump is particularly suitable for metering
- shear-sensitive and
- highly viscous liquids.
Acc. to a Prominent press release: “The results of extensive test series prove that the DFXa easily dispenses media with viscosities of up to 200,000 mPas! The intuitive user interface, already known in ProMinent diaphragm metering pumps, ensures simple operation, and is identical across all ProMinent series. Every user can quickly find their way around and make essential settings, in next to no time.”
Within a few minutes, like the other ProMinent metering pumps, the DFXa can be connected to the web-based fluid management platform, Dulconnex. With this cloud-based solution, dispensing processes can be monitored in real time, downtimes can be avoided, and fully automatic reports can be generated. Digitally networked, all necessary information for optimal system control is available and always ensures smooth processes.
