Automation increases the reliability of fluid mixing
Ingersoll Rand
The ARO Electronic Interface pumps (photo) are air-operated diaphragm pumps that — when paired with the company’s ARO Controller — provide accurate, electronically controlled batching and container filling. The ARO Controller provides an automated, closed-loop system with proprietary logic that ensures that the pump is always fully primed. This helps to control flowrates and provides pinpoint control for numerous fluids and applications throughout the chemical process industries (delivering±1% repeatability when dispensing or batching, says the company). The ARO Controller works seamlessly with company’s ARO EXP Electronic interface pumps, and can be integrated with many existing ARO EXP pumps when an electronic interface package is added. This combination provides the user with a fully automated, multi-pump system that can handle batching as well as container and tank filling. The interface is pre-programmed with eight languages, supporting the needs of a diverse workforce and global operations. It can also be programmed with a variety of remote triggers (to initiate auto-shudown and send data and service alerts to operators). These can be customized for the application at hand. Such triggers could, for example, notify operators when it’s time for predictive maintenance, when liquid levels are low, or when a leak has been identified. — Ingersoll Rand, Davidson, N.C.
