OPERATING CYCLE

 POWER STROKE: As the CONTROLLER air or gas enters the PNEUMATIC DRIVE CYLINDER, the PISTON-PLUNGER ASSEMBLY is driven
 down into the FLUID CHAMBER, displacing fluid and compressing the RETURN SPRING. As the plunger displaces the fluid, the rise in
 pressure closes the SUCTION CHECK VALVE and opens the DISCHARGE CHECK VALVE. A precise amount of fluid, corresponding to the
 stroke of the plunger, is discharged.

 SUCTION STROKE: When the air or gas is exhausted from the PNEUMATIC DRIVE CYLINDER the RETURN SPRING forces the
 PISTON-PLUNGER ASSEMBLY to return to its original position. The drop in pressure in the FLUID CHAMBER caused by the
 retraction of the piston allows the spring loaded DISCHARGE CHECK VALVE to close and the SUCTION CHECK VALVE to open so
 that the FLUID CHAMBER is again filled and ready for the power stroke.

 Reading The Graphs




      The performance curve graph illustrated here is, in fact, two
      graphs overlayed upon each other. The first, determines the
      air/gas pressure, illustrated in red. The second, determines
      your discharge pressure, shown in black. Where these two
      overlayed graphs intersect define your optimum flow range.

    The PNEUMATIC RELAY is a pilot operated valve designed to provide the higher
    air or gas flow rates necessary for PNEUMATIC DRIVE CYLINDER diameters

PLUNGER MATERIAL SELECTION
 The materials available vary in hardness and chemical compatibility. We offer three materials based on our many years of industry experi-
 ence with various chemicals. Hardness is a key property when selecting the proper plunger material. Our experience has shown that the
 harder plunger materials not only provide longer plunger life, they also provide greater seal life. A hard plunger is a must when pumping
 a chemical that is prone to crystallization or if the chemical is contaminated. Of course both of the above conditions will affect seal life.
 Below is a table that compares the chemical compatibility and hardness properties of each material.

     We recommend the use of ceramic because of its extreme hardness and excellent chemical inertness.




SEAL MATERIAL SELECTION
 The seal material must be chosen to satisfy both the chemical compatibility and the pressures/temperatures at which you are operating.
 Below is a general guideline for seal material selection.

  Selecting the proper seal material for your application is important. We suggest using the harder plastic seals (PE, TC or TG) whenever possible
  because they provide excellent wear life. The elastomers (V, BR,K or EPR) offer enhanced sealing at low pressure because they are soft and more
  compliant than the plastics. However, the elastomers do not provide the same toughness or wear resistance.
