Design Envelope 4312 Twin Pumps

Posted by Armstrong Fluid Technology on Nov 30, 2018 6:26:01 AM

As Seen on - November 08, 2018

Armstrong’s Design Envelope 4312 is a pipe-mounted, two-pump unit with integrated intelligent controls for full redundancy during operation. Vertical in-line design eliminates the need for inertia bases, housekeeping pads and flex connectors, and reduces piping requirement. It saves up to 75 percent in energy over comparable traditional constant-speed or variable-frequency-operated pump installations. Reduces operational greenhouse gas emissions at an equal ratio. Integrated controls eliminate procurement, installation (including wiring), calibration and upkeep of differential pressure sensors. Power range is 1 horsepower to 40 horsepower (0.75 kW to 30 kW). Performance range is up to 1,250 gal. per minute (80 L/s) flow and 250 ft. (75 m) head.
