1.  Theory of Operation 

 

See Figures 13 and 14 for a cross-sectional view of the WSP™ ARV 

and a description of its operation. 

 

 

Figure 13: Valve in Open Position

 

 

 

Figure 14: Valve in Partially Closed Position

 

 

Air from the pump casing passes through the bypass line and the air release valve to the 

wet-well during the priming cycle. (Figure 14).
