Armstrong Fluid Technology has introduced that Design Envelope pumps with Permanent Magnet motors are now available NEMA 4X/IP66 rated, for out of doors installation.
Featuring superior efficiency mapping technology and load-limiting logic, the new pumps cut back power consumption by as much as 30% compared to pumps provided with a unfastened variable velocity drive. Together with new more environment friendly pump hydraulics, the brand new 1 to 10hp pumps can save an extra 20% compared to competing integrated products with induction motors.

‘The conventional method to rooftop and outdoor pumps is to put in VFDs in a central, outdoor-rated management panel, separate from the pumps. This provides unnecessary prices and requires a bigger footprint,’ said Zeljko Terzic, Global Offering Manager, Pumps. ‘Our new Design Envelope pumps function integrated controls for a reduced footprint and substantially decreased set up costs.’
