| How do you determine the horsepower for a pump? |
| For a positive displacement, reciprocating pumps, the
horsepower is determined by multiplying GPM x PSI and
dividing by 1714 x % Efficiency. For centrifugal pumps,
horsepower is determined by multiplying GPM x Total Head
x Specific gravity and dividing by 3960 x % Efficiency.
Higher viscosities are possible with a PD pump, provided
you adequately deliver the liquid to the pump. A standard viscosity
guide for CAT PUMPS is up to 500CPS or 2500SSU. With the
centrifugal pumps, viscosity and specific gravity can significantly
increase the amount of horspower required and the horsepower must be
carefully calculated to avoid overloading the motor. |
