Armstrong launches medium vary line

pressure gauge has added a new dimension vary to its Design Envelope Permanent Magnet pumps which are engineered to deliver 20% decrease operating prices than variable speed pumps with standard induction motors.

The new pumps can be found with motors starting 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 a number of additional design features which make them more energy-efficient and cost-effective. These include Armstrong’s patented Parallel Sensorless Control which levels a quantity of pumps and regulates output for finest effectivity throughout the complete pump array, saving 10-30% in operating costs. They also have adjustable design points and setpoint based mostly on precise on-site conditions, a quadratic pressure control curve that provides more effectivity than a linear pressure management curve and a constant-flow perform for maintaining a desired flow fee in recirculation purposes.
The new pumps additionally supply superior connectivity through Armstrong’s Pump Manager, a Cloud-based efficiency monitoring service, which provides high levels of analytics and insights along with alerts, alarms and knowledge storage.
David Lee, providing manager, Armstrong Fluid Technology, said: “Better efficiency at higher RPMs implies that in some circumstances a smaller Design Envelope Permanent Magnet Pump can deliver the identical flow and pressure as a larger, costlier competing mannequin, These new pumps additionally characteristic smaller dimensions and are cheaper to purchase and set up as a result of permanent magnet motors supply a considerable reduction in both dimension and weight.”
