How does more cost less?
In calculating the requirements for a swimming pool’s pumping system several elements must be considered. The quantities of these “inlet” devices in combination with piping distances and piping sizes all have a restrictive value on the movement of a given desired quantity of water and this is referred to as the “negative suction lift requirement (NSL)”.
Essentially the impeller is designed to draw water from the inlet side and then push water out of the outlet side. The more efficient this is done according to the pump’s impeller design the less electricity is used during the pumping process.
QUESTIONS TO ASK
- What horsepower rating is my pump and why has that size been selected?
- What is the “Service Factor” of the pump selected?
- How many hours per day will I need to operate my filtering system?
- What is the Kilowatt electrical consumption and designed water flow rate of my pumping system?
- What will my pool cost to operate, monthly, yearly and over it’s lifetime?
Note: If your pool builder can’t answer these questions upon presenting a design a crucial component of the design is missing.
