I think the Marine Depot picture of the Dart is wrong and outdated. The one pictured is the Baldor motor but the one they sell is the Hubbel motor. If you read from the Marine Depot site it says
"The Dartâ"žÂ¢ is the quietest pump on the market. Ideal applications for this unit are aquariums 100- 200 gallons. The Dartâ"žÂ¢ is great for close loop reef systems requiring high turnover. This unit is rated for moderately low head pressure and a maximum flow rate of 3600gph, shut off head of 12 feet and a maximum wattage of 160/ 1.4 amps. Our low speed, 1/8 HP Hubbel® motors have extremely low heat transfers.
