Armstrong launches medium range line

1 min read

Armstrong Fluid Technology has added a new size range to its Design Envelope Permanent Magnet pumps that are engineered to deliver 20% lower operating costs than variable speed pumps with standard induction motors.

The new pumps are available with motors ranging from 15 hp to 50 hp and operate at NEMA Ultra-Premium Efficiency levels.

The new pumps are available with motors ranging from 15 hp to 50 hp and operate at NEMA Ultra-Premium Efficiency levels that exceed the efficiency targets of both the US Department of Energy and the European Union.

The new Armstrong Design Envelope Pumps have several additional design features which make them more energy-efficient and cost-effective. These include Armstrong’s patented Parallel Sensorless Control which stages multiple pumps and regulates output for best efficiency across the entire pump array, saving 10-30% in operating costs. They also have adjustable design points and setpoint based on actual on-site conditions, a quadratic pressure control curve that provides more efficiency than a linear pressure control curve and a constant-flow function for maintaining a desired flow rate in recirculation applications.

The new pumps also offer advanced connectivity via Armstrong’s Pump Manager, a Cloud-based performance tracking service, which provides high levels of analytics and insights along with alerts, alarms and data storage.

David Lee, offering manager, Armstrong Fluid Technology, said: “Better performance at higher RPMs means that in some cases a smaller Design Envelope Permanent Magnet Pump can deliver the same flow and pressure as a larger, more expensive competing model, These new pumps also feature smaller dimensions and are less expensive to purchase and install because permanent magnet motors offer a substantial reduction in both size and weight.”
