Well Pump Sizing

Water HP = GPM x TDH / 3960

Brake HP = Water HP / Efficiency

The constant 3960 comes from converting GPM and feet of head to horsepower units. Submersible pump efficiency is typically 50 to 70 percent. Multiply HP by 746 to get watts.

Ejemplo Resuelto

10 GPM pump with 200 ft TDH, 60% efficiency.

  1. Water HP = 10 x 200 / 3960 = 0.505 HP
  2. Brake HP = 0.505 / 0.60 = 0.84 HP
  3. Motor = 0.84 x 746 = 627 W
  4. Select a 1 HP submersible pump.
