Progressive Cavity Pump

The PCP Series of progressive cavity pumps bring superior volumetric accuracy to your most demanding dispensing applications. Progressive cavity pumps feature a machined rotor that couples with a rubberized seal to assure drip-free operation with a wide range of viscous chemistries. Each servo-controlled rotor displaces a fixed volume of material per revolution. This true positive displacement process assures consistent volume regardless of slight material variations.

The PCP Series features five different rotor sizes allowing the end user to select their ideal flow rate. An optional carbide rotor allows processing of filled or abrasive chemistries while extending the life of the rotor.

The PCP Series has many additional integrated features including:

  • Programmable flow rate for a customized dispensing process
  • High precision dosing within ±1%
  • Continuous dispensing process for efficient operation and no refilling
  • Self-sealing operation prevents dripping
  • Optional carbide rotor
  • Luer Lock outlet connection

Applications

Dam & Fill

A two-step process of first dispensing a high viscosity fluid around the perimeter of a device or electronic circuitry, and then dispensing a low viscosity fluid within the perimeter to fully encase the components. The dam can be applied as a single or multi-layer bead depending on the target fill height required.

Dam & Fill Details

Dispensing

Dispensing can extend across numerous industries and applications that require dosing in an accurate and controlled manner.  PVA's award winning valves and pumps are available to dispense a broad spectrum of chemistries to meet the requirements of your most demanding applications.

Dispensing Details

Encapsulation & Glob Top

Applying an epoxy or silicone-based fluid that completely covers a defined area around a flip chip or wire bonded component. This provides mechanical shock and vibration stability, as well as environmental protection from moisture and foreign objects.

Encapsulation & Glob Top Details

Gasketing

Also known as "form-in-place gasketing," this application dispenses one or two-part liquids into a groove or onto a flange that will cure to form a seal against liquids and gases. This automated process eliminates the task of assembling a die cut or pre-made gasket. Additionally, geometries can easily be modified for other design.

Gasketing Details

Potting

The process of filling an enclosure that holds electronic circuitry, with a liquid that when cured completely encases the unit. This provides mechanical stability during shock and vibration as well as environmental protection from moisture and foreign objects.

Potting Details

Thermal Interface Materials

A thermal interface material (“TIM”) fills gaps between mating surfaces with a substance that improves thermal conductivity beyond the air that would have otherwise filled that gap. The TIM acts as a conductive bridge that greatly improves heat transfer between between a heat-generating device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
