เกจวัดแรงดันน้ำ has added a brand new size range to its Design Envelope Permanent Magnet pumps which are engineered to deliver 20% lower working prices than variable speed pumps with normal induction motors.

The new pumps can be found with motors starting from 15 hp to 50 hp and function 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 extra design options which make them more energy-efficient and cost-effective. These embrace Armstrong’s patented Parallel Sensorless Control which stages multiple pumps and regulates output for greatest effectivity throughout the complete pump array, saving 10-30% in working costs. They even have adjustable design points and setpoint based mostly on precise on-site circumstances, a quadratic stress control curve that gives more efficiency than a linear pressure management curve and a constant-flow perform for sustaining a desired move price in recirculation functions.
The new pumps also supply advanced connectivity by way of Armstrong’s Pump Manager, a Cloud-based performance monitoring service, which provides high levels of analytics and insights along with alerts, alarms and knowledge storage.
David Lee, providing supervisor, Armstrong Fluid Technology, said: “Better efficiency at higher RPMs means that in some cases a smaller Design Envelope Permanent Magnet Pump can ship the same move and pressure as a bigger, dearer competing mannequin, These new pumps also function smaller dimensions and are cheaper to buy and set up as a result of permanent magnet motors offer a substantial discount in each size and weight.”
