electriccentrifugalindustrial

ApplicationsHVAC-system pumping; general purpose pumping; industrial/process pumping (water or glycol based) DescriptionMotor-mounted pump unit with integrated intelligent controls for space-saving installation and superior energy performance. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations Materials Cast iron or ductile iron casing Bronze impeller Sintered silicon carbide mechanical seal ConfigurationOn-board Intelligent Variable Speed controls with Sensorless control. Controls enclosure UL type 12 for indoor applications. Supplied with NEMA premium motor for significant reductions in energy usage. Performance rangeUp to 1000 USgpm (63 L/s) flow; up to125 ft (38 m) head Temperature250oF (121oC) Power Range1 hp to 7.5 hp (0.75 kW to 5.5 kW) Size1.5" to 6” (40 mm to 150 mm) Lowest installed cost Integrated intelligent controls eliminate procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensors Superior energy performance qualifies for significant cost recovery under utility and government rebate programs Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost
