Injection process is essential for many industrial applications especially in water desalination and water treatment market. The new concept of injection, line bleeding injection pump (LBIP) , opens a door for injection processes of simpler and effective injection facilities with relatively low cost and less maintenance requirements. The concept of LBIP is to utilize the pressure inside the line and intensify it to produce higher pressure than the line pressure to inject chemicals inside it. Certain amount of water should be bleed out from the line. The amount of bleed water then could be either recycled back to the line or drained back to the intake. The aim of this study is to develop LBIP design to be double act injection pump. Double-act LBIP design is promising to be more effective and low price design for relatively higher doses injection applications. It has no spring. The developed design will act as two pumps in one unit using very simple design and traditional materials. This concept will take the cost to its minimum value. The double-act LBIP price is promising to be very competitive compared to other injection pump types. Double-act LBIP is equipped with 3 adapters as a simple and accurate variable displacement facility that gives the design a strong potential as metering injection pump with wide range of injection ability (20-1000 liter/day). Both single-act and double-act LBIP designs require no driving power except for the line pressure itself. This concept is promising for researches of developing renewable energy with seawater desalination units in remote areas.
