Meter Mix Progressive Cavity Pump

The MM-PCP is a servo motor driven pump with closed-loop feedback control. It provides highly accurate meter mix dispensing of two-part material. As the various parts of the pump are created in modular form, it can be easily configured to match the unique mixing ratio or asymmetrical dispensing needs of any dispensing application.
The MM-PCP dispenses with a rotary displacement action based on the eccentric screw pump principle. During operation, the pressurized fluid within the wet body chamber flows into either one of the two alternate cavities that are “opened” as the eccentric screw rotates. As the rotor continues to rotate, fluid moves from one sealed cavity to the next in a downward trajectory motion. The dispensed volume is determined by the rotor rotating speed and the stator cavity size.
Since the volume of fluid held in each cavity is fixed, the MM-PCP is able to provide continuous volumetric dispensing independent of fluid pressure fluctuation or changes in fluid viscosity over time. Quality of the system is further enhance by optional pressure sensors. These sensors provide continuos pressure monitoring to detect changes that can affect dispensing or mixing ratio.
The MM-PCP is controlled by the controller PCP-CL to form a complete dosing system. The controller is easy to use and operates with different programming modes to match the unique needs of any dispensing application.
