New Imo® TX2020 rotary positive displacement three-screw concept pump can manage own performance, order own replacement parts

Colfax Corporation (NYSE: CFX), a global leader in fluid-handling solutions, has announced the development of an intelligent concept pump with the ability to monitor its performance, adjust to changing conditions and order its own replacement parts – all without human supervision. The company unveiled the Imo® TX2020 concept pump at the Shipbuilding, Machinery & Marine (SMM) International Trade Fair in Hamburg, Germany, in September.

“This is a significant advance in rotary positive displacement three-screw pump technology,” said Benny Strom, general manager of Colfax’s Imo AB business, “assuring continual, precision pumping performance for applications in which minimizing downtime and maximizing pump life is critical.” While Colfax highlighted marine applications at SMM, the TX2020 concept pump also holds much promise for remote pipeline locations or power plants and other facilities that need to operate at high capacity, Strom added.

Developed at the Colfax facility in Stockholm, Sweden, where the rotary positive displacement three-screw pump was invented, the TX2020 concept pump continually monitors flow rate, pressure, liquid viscosity (thickness) and energy consumption. If it determines adjustment is necessary to maintain flow, it can change speed or heat the liquid, to lower its viscosity.

The concept pump was designed for a variety of configurations; for example, it can operate by itself at a remote pumping location or be connected to a network of pumps managed at a central office.

Imo TX2020 concept pump software includes a preventive maintenance calendar and – based on foreseen needs or detected problems – the ability to determine which parts need replacement and issue a purchase order for them. For marine applications the TX2020 concept pump can even provide a preprogrammed list of the service stations closest to the vessel, with full coordinates and contact details. The software also maintains precise records, in the form of an electronic log book operators can use to track performance trends over time.

According to Karl-Johan Brink, director of sales and marketing for Imo AB, Imo is currently speaking with customers, owners and module builders about the Imo TX2020 concept pump. “We’re incorporating the voice of the customer,” he noted, “channeling feedback and input into further development of the concept pump for sale and production.
