A sand pump for a pool isn't actually a pump; it's a pool sand filter that uses a pump to circulate water. This filter employs sand to cleanse pool water, effectively removing debris and contaminants.
How a Pool Sand Filter Works
Here's a breakdown of the process:
- Water Intake: The pool pump draws water from the pool.
- Filtration: The water is directed into a tank filled with a special type of sand.
- Contaminant Removal: As the water flows through the sand, particles, dirt, and other impurities get trapped within the sand bed.
- Clean Water Return: The purified water then flows back into the pool.
Here is a summary in a table:
| Step | Description |
|---|---|
| 1. Water Intake | Pool pump pulls water from the pool. |
| 2. Filtration | Water flows into the sand filter tank filled with sand. |
| 3. Contaminant Removal | Debris and contaminants are trapped as water flows through the sand. |
| 4. Clean Water Return | Filtered, clean water flows back into the pool. |
Key Features of Pool Sand Filters:
- Effective Filtration: Sand filters are highly effective at removing a wide range of particles.
- Low Maintenance: Compared to other types of filters, sand filters generally require less frequent maintenance.
- Backwashing: Periodically, the filter needs to be backwashed to clean the trapped debris from the sand, reversing the water flow to flush out the contaminants.
- Durability: These filters are built to last for many years.
Benefits of a Sand Filter
- Cost-effective: The sand is relatively inexpensive and long-lasting.
- Easy to Operate: Once set up, sand filters are generally easy to use.
- Good for Various Pool Sizes: There are different sizes of sand filters available to suit the needs of most pools.
Essentially, a pool sand filter works in conjunction with a pump to keep your pool water clean and clear by physically filtering out impurities as the water circulates through the sand.
