520Di Ideal for Fully Automated Aseptic Fill/Finish in Biotech and Pharmaceutical
Drug Manufacturing
advertisement
Watson-Marlow Pumps Group, the leading manufacturer of peristaltic pumps, launches its 520Di dispensing pump for accurate metering, dosing and transferring of sensitive fluids in sanitary environments. Ideal for filtration, fermentation and dispensing applications, the 520Di accepts eight different tubing materials and sizes up to 9.6mm for flow rates ranging from 4 microliters/min up to 3.5 liters/min and pressures up to 100 psi.
The 520Di combines the rugged ability to perform in process applications with dispensing and dosing programming to handle the most delicate laboratory environments and the accuracy demanded in filling lines in Biotech and Pharmaceutical production. The 520Di is also suited for benchtop media or reagent preparation in laboratory suites – filling or inoculating bottles, vials, petri dishes and media bags
Featuring spring loaded stainless-steel rollers and a larger swept volume pump head, the 520Di combines the gentle handling of fluids with a greatly increased capacity. The gentle nature of the peristaltic pumping action is important for this type of application because of the fragility of protein string, enzyme-based vaccines and other biochemicals, which can be easily damaged.
The 520Di has full dispensing capability, enabling accurate batch dispensing and automatic or single-shot operation. While the product is being pumped, a ramp and drip feature allows soft start and graduated dosing to reduce splashing or foaming. Users are also able to carry out periodic dose recalibration ‘on-the-fly’ without disturbing the flow of the batch. Up to 50 individual dispensing programs, including all dose parameters and calibration, can be stored in the memory with full, 8-character file names.
The 520Di’s new brushless DC motor has a speed range of 3500:1 and over a million to 1 flow range, offering total flexibility of speed control combined with precision and repeatability for the most demanding dispensing applications. A number of different pumpheads can be fitted to suit the user’s needs.
Combining extraordinary levels of functionality with an on-screen menu, the 520Di features an easy-to-use tactile membrane keypad and an alphanumeric display in English, German, French, Spanish and Italian. The IP31 version has full RS232 control via serial communications and the IP66/NEMA 4X model has full RS485 control via serial communications.
Every Watson-Marlow peristaltic pump is an inherent metering pump with repeatability at 99.5%. Many models include integral digital drives with PROFIBUS or SCADA control in NEMA 4X washdown enclosures. These self-priming pumps accommodate flow rates from 0.1 microliter to 350 gpm, and are extremely durable, withstanding pressures up to 232 psi. There are no internal universal joints, valves, dead corners, or glands to impede flow and these pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30’ suction lift.
