1.3 Site selection
Self‐Priming application: Pump can operate in 1.5 to 6.5 m depth within and it changed because of temperature, pressure, liquid thickness.
Positive suction head application: Pump use this way in clean barrel through popularly. It operates useful at 0.5 to 0.8 bar for inlet pressure.
Submerged application: All pumps can operate inside the liquids. But it’s necessary to sure the outlet must exhaust outside the liquids.

Part 3: Descriptions and explanations necessary for the understanding of drawings
By filling the air chamber (A) the right hand diaphragm is pressed towards the outside. The piston rod thereby pulls the left hand diaphragm to initial position. Valve ball (Bottom left) is pulled out of its position, liquids (blue arrow) flows into the chamber (B). At the same time valve ball (Top left) is fixed in end position by the vacuum. The chamber (B) is thus completely filled with liquids. (see Fig. A.)
After switching of the control valve air flows into the air chamber (B), the air chamber (A) is vented. (see Fig. B.)
liquids (right hand) is drawn in , liquids (left hand) in the chamber (B) is displaced to the outside. Valve ball (Bottom left) presses down, closes and valve ball (Top left) opens the flow path for liquids to the pressure outlet port. that the chamber (A) is already filled with liquids. (see Fig. C.)
By switching of the control valve the air chamber (A) is filled, liquids is drawn into the chamber (B) and the liquids from the chamber (A) is displaced. This sequence is repeated First step. (see Fig. A.)
