Armstrong Fluid Technology has introduced a new size range of 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 from15 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.

These new pumps also feature smaller dimensions and are less expensive to purchase and install"
David Lee, Offering Manager at 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.”
David Lee adds, “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.”
New pumps featuring multiple design innovations
Beyond the motor efficiency, a number of additional design innovations make the new Design Envelope pumps more energy-efficient and cost-effective. These include:
- Armstrong Fluid Technology’s patented Parallel Sensorless Control stages multiple pumps and regulates output for best efficiency across the entire pump array, saving 10 to 30% in operating costs.
- Adjustable design points and setpoint based on the actual on-site conditions.
- A quadratic pressure control curve provides more efficiency than a linear pressure control curve.
- A constant-flow function for maintaining the desired flow rate in recirculation applications.
- Advanced connectivity via Armstrong’ Fluid Technology’s Pump Manager, a cloud-based performance tracking service, which provides industry-renowned analytics and insights, along with alerts, alarms, and data storage features.
