Applications and functions

Applications
The APF-Cleaner system can be used for pump stations equipped with Xylem Water Solutions type CP/DP 3085-3300 pumps in both standard and Ex-versions.

APF-Cleaner is especially effective in combination with the so-called TOP-stations; this due to the narrow and shallow design of the sump bottom, which results in a minimum of residual water after pumping down.
 
Cleaning
At regular pumping cycles, the pumps are started and stopped by a primary level control system.

But, on a pre-set number of cycles each 24 hours, the APF-Cleaner overrides the primary controller to perform a "cleaning" cycle.
 
Cleaning frequency
The number of cleaning cycles per 24 hours can be selected on the front of the APF-Cleaner to 0, 1, 3, 5, 10, 15, 25 or 40 times.
 
Stop function
When the water in the sump has dropped to such a level that the pump begins to draw air, the motor current will drop. The APF-Cleaner detects this and stops the pump.
