10/31/05 9 of 12 Pump Drivers Most common Electric Motor Standard electric motor sizes (BHP) 0.5, 0.75, 1, 1.5, 2, 3, 5, 7.5 10, 15, 20, 25, 30, 40, 50, 60, 75 100, 125, 150, 200, 250, 300, 350 400, 450, 500, 600, 700, 800, 900 1,000, 1,250... Motor size must be matched to pump capability Motor rating should exceed requirements at design operating point due to flow variability Full pump capacity can be achieved only if the available BHP equals that required at the end of the pump curve Capital cost => motor rating (max BHP) Operating cost => actual hydraulic HP with pump and motor efficiencies applied. Driver alternatives Steam turbine, gas turbine, power recovery turbine, gas powered engine (recip)
