Pump drive module saves energy ABB has introduced a new drive module that features an in-built energy saving calculator, embedded Modbus and drive to drive link. In addition ABB says that the module offers a good user interface with a series of assistant wizards, integrated safety functions and modular hardware and software along with a removable memory unit. It also uses a high-performance motor control platform, Direct Torque Control. Targeted specifically at OEMs and system integrators, the ABB industrial drive modules are designed for industrial machinery and applications including pumps in the power range of 1.1-400 kW, with voltages from 380-480 V. The energy saving calculator indicates the amount of energy

consumed and the amount of energy saved in kW hours and money, as well as showing the duration curve showing the load profile of the drive. It also has an automatic energy optimizer. www.abb.co.uk/energy
Frequency converters control centrifugal pumps Grundfos has introduced the CUE range of wall mounted frequency converters with e-pump functionality for new projects as well as for retro-fit/refurbishment purposes. The controllers allow the speed of virtually any Grundfos pump irrespective of its size, power range or application area to be controlled. The family is suitable for all centrifugal pump types in all application areas. The series offers a whole array of features including plug-and-
pump installation and along with the in-built control and monitoring options comes the automatic energy as well as the energy savings that variable speed operation brings. Grundfos adds that CUEs can be used in both new and existing pump installations where an integrated solution will either not fit, is undesirable or is prohibited, for example in ATEX areas. www.grundfos.com
Increased reliability with JetPlex pumps Flow International Corporation has developed JetPlex, a waterjet pump which it says has the highest possible pressure stability available in a pump, along with improved performance, reliability and predictable maintenance. According to the company, using the JetPlex waterjet pump can reduce wear and tear on
pump components because less energy is wasted as transferred heat to a hydraulic system. This in turn leads to lower utility bills, because less power and water are consumed per horsepower of output, and there are likely to be lower maintenance costs. www.flowcorp.com www.worldpumps.com
