New Armstrong pumps provide design margin
Armstrong has launched two pump ranges under its Design Envelope category. They are the Series 4300 IVS vertical inline pump and the Series 4302 dualARM IVS pump designs.
These pumps can accommodate reasonable changes in operational demands in the future without the expense of replacement or a drop in energy efficiency. They have a built-in ‘safety net’ so the designer does not have to trade off the energy efficiency of the installation by oversizing equipment to give a safety margin.
These pumps have Armstrong’s Sensorless control technology to adjust pump operation to maximise operating efficiency, including at part loads. For many applications there is no need to install a remote pressure transducer. For more complex applications, these pumps can be controlled by Armstrong’s Integrated Pumping System or a BMS.
Both ranges have built-in inverter technology to control pump speed. Embedded in the memory of the speed controller are pump performance curves for the complete range of operating speeds.
The new range includes single- and dual-head pumps with motors up to 55 kW. Prefabricated pump packages can also be supplied, complete with built-in controls.
