Reliable Self-Priming Operation
Before any centrifugal pump will perform, it must first be primed; that is, air or gases expelled from the suction and impeller eye area, and replaced with liquid.This is no problem when the pump is submerged (submersible or vertical sump pumps) or when liquid supply is above the pump. However, when suction pressure is negative, air must be evacuated to accomplish pump priming.
The 3796 is designed to insure that a sufficient quantityof liquid to reprime is always retained in the priming chamber...a compact, integral and completely functional self-priming pump.
