Types of Suctions in a Dosing System
-
Suction lift application
A suction lift occurs when the fluid level in the tank is positioned below the pump inlet. The suction becomes essential for pulling fluid from the chemical tank.
-
Flooded suction application
Flooded suction is defined by a tank fluid level that is positioned higher than the pump inlet. The pump inlet has constant positive pressure.
Based on the fluid level within the tank, there might be a flooded suction, such as when the tank is full, or a suction lift, as seen when the tank is nearly empty.
