Mag-drive micropump for leak-free high-flow pumping
A new addition to the established Micropump range of compact, lightweight pumps is the CA Series centrifugal pump which is suited to high-flow liquid-handling applications where magnetic drive, leak-free pumping will be appreciated. Available through Michael Smith Engineers, these miniature pumps can be easily incorporated into the designs of many systems and provide flow rates to 25l/min and differential heads up to 14m with maximum rated system pressures of 13.8bar (200psi).
When the CA Series centrifugal pump is integrated with Micropump's new DC electromagnetic Eagle Drive, it is suitable for OEM circulating and transfer applications requiring higher flows and lower differential pressures. The Eagle Drive is a compact electromagnetic drive with no moving parts. This innovative brushless DC drive can be run on a wide range of power supply voltages from 10V to 38V DC, giving an output speed range between 250-10,000rpm, and has variable speed operation using 0-5V DC signal. Other features include over temperature, under voltage and internal fault output signals, surface-mounted electronics, built-in microprocessor control and tachometer output, ensuring simple system integration.
The CA Series pump's magnetic drive removes the need for direct drive connection to the pump impeller and so eliminates the potential leak points associated with shaft seals used in other types of pump. This feature, combined with the pump casing passageway design, which is proportioned so fluid maintains its velocity head with minimal energy loss, contributes toward a more energy-efficient fluid delivery with lower input power required. In addition to the benefits of reliable, leak-free, energy-efficient pumping, the CA Series is designed with fewer moving parts and this contributes towards easy servicing and a long life performance.
Complementing the simple construction of the CA Series pump are the materials used for its key components; the impeller and wetted parts are made of 316 stainless steel ensuring exceptional chemical compatibility, abrasion resistance and long service life, even when operating in challenging applications.
