DIFFUL SOLAR PUMP--Difference Between Pool Filter & Pool Pump
Diatomaceous Earth Filters
These are usually a bit more expensive than either of the other two filters. They work by coating the filtering mechanism with fine diatomaceous earth (DE). The DE coats the internal filter system and removes the tiniest of dirt particles. Known for their ability to screen out particles as small as three microns, DE filters are popular for those who want the cleanest pool water.
Cleaning a DE filter includes backwashing and/or manual cleaning. You must add more DE to the system each time it’s cleaned. At approximately $20 for 15 pounds of DE (which is more than enough to last a full season or more), it is much less expensive to maintain than a cartridge filter.
Pool Pump
The pool pump pulls the water from the pool into the filter. The pump consists of the pump basket (which collects debris and leaves), the impeller (a fan-like mechanism) and the water discharge. The discharge is the connection point that pushes the water from the pump into filter’s housing.
Pool Pump Motor
Just as important as the pump is the motor. The motor gets everything moving. Without the motor, the water could not leave the pool to enter the pump. The motor initiates the movement necessary to create the vacuum to pull the water from the pool into the pump.
