Finalist in Equipment Level Sensors and Controls in Consulting-Specifying Engineer's 2011 Product of the Year competition
The Toshiba International Corp. P9 is an adjustable-speed drive for pump control. It incorporates virtual linear pump (VLP) technology to control pressure, temperature, or flow. The product linearizes the traditional pump curve, providing systems with variable pumping control. Users can configure the system in five steps, and the drive self-calibrates to eliminate common pump anomalies. The setup wizard guides the user through the process and can define operating boundaries by establishing a minimum and maximum VLP point. Protective features include start and stop points, sleep timer, run external devices feature, and sealing water/vacuum priming feature.
