Parts List

• Discharge check valve ball
AP-2 AutoPumps
In both the Bottom-Loading and the Top-Loading models, the fluid is pushed out of the pump
through a check valve located at the top of the pump. This check valve prevents the fluid
from reentering the pump.
Bottom-Loading AP-2/BL
The Bottom-Loading AutoPump fills through a check valve at the bottom of the pump.
There are two lengths of AP-2/BL: long and short. The fluid level in the well can be
drawn down to 35 inches from the bottom of the long BL, and 20 inches from the bottom
of the short BL (See Figure 3)
Top-Loading AP-2/TL
The Top-Loading AutoPump fills through a check valve at the top of the pump, therefore
the fluid level in the well will never go below the level of this check valve. There are two
lengths of AP-2/TL: long and short (See Figure 4)
