Consistent flow rates in abrasive, viscous pumping application

520Du low speed multi channel pumpA pharmaceutical company in Columbus, OH needed to meter ethyl alcohol, Glass bead and polyvinylprillidone at 15-50 milliliters per hour through multiple channels. These abrasive chemicals have a high viscosity and the company had previously tried a syringe filling machine pump, but could not achieve a continuous flow.

The Watson-Marlow 520 pump was suggested as a possible solution for the abrasive, high viscosity chemicals. Peristaltic pump technology can effectively handle difficult chemicals because nothing but the tube contacts the abrasive viscous fluid. This simple pumping action means less maintenance and more performance. The 520Du pump was selected for drive stability at low speeds, while the 32-channel cassette head gives the customer the number of channels needed for their process, effectively getting 32 channels of flow with one pump.

The new pump was exactly what the company needed and with their accurate, consistent and continuous flow they are able to meter the abrasive chemicals with minimal maintenance and downtime.
