PV202K-TCM Cartridge Drive System

PRODUCT DESCRIPTION

The PV202K-TCM Cartridge Drive System is a cost effective meter mix system for dispensing two component thermally conductive materials that contain abrasive fillers.

The system operates by metering material directly from disposable plastic cartridges via a linear drive. As the drive advances, material is positively displaced to the two-part dispense valve. There are no pumps or seals to wear out providing a low maintenance solution.

The entire system is packaged on a sturdy frame with swivel castors and brake for easy mobility. The unit also provides neat and convenient controls integration to any PVA robot.

The PV202K-TCM has many integrated features including:

  • Closed loop servo drives ensuring accurate ratio and repeatability

  • Pressure transducers to monitor system performance

  • Automatic system pre-charge pressure after cartridge changes

  • Easy to load cartridge clam shells

  • Door interlock to ensure operator safety

  • Low level detection

  • Low maintenance

SPECIFICATIONS

  • Overall Foot Print: 30” X 27” (760 X 685 mm)image

  • Material Supply: 20 oz Semco Cartridges (600 cc each) (for 1200 cc kits)

  • Flow Rate: 5-20 cc/min (Dependent upon material viscosity and needle tip used)

  • Options/Accessories: PC200-TCM 2-Component Carbide Dispense Valve Heated Hoses

 

MX4000 Gear Pump Meter Mix Systems

PRODUCT DESCRIPTION

PVA’s MX4000 Series Gear Pump Systems are an ideal choice for most non-abrasive meter-mix dispensing applications.

Gear pump designs feature continuous material flow with no recharging necessary. PVA pumps are designed specifically for processing a wide range of adhesives and sealants.

Closed loop servo drives enable the operator to program the mix ratio, shot size, flow rate, pressure control, vacuum degas, recirculation, and auto purge functions via a menu-driven HMI.

PVA's gear pump metering systems have many additional integrated features including:

  • Continuous pulse-free flow

  • High pressure capability up to 4000 psi

  • Wide viscosity range to 3 million cps

  • Superior resolution as pumps are sized to each application

PVA manufactures single and plural component metering systems customized to each specific requirement. Standalone metering systems not integrated onto a PVA robotic platform come with a standalone controller allowing multiple dispensing profiles to be stored. Within each profile, automatic purge modes and variable flow rates are available. PVA metering systems feature closed-loop servo drives for added repeatability and dispense volume accuracy. All standalone meter-mix systems include an enclosure and are mounted in a frame or custom cart with casters.

SPECIFICATIONS

  • Mix Ratio: Fixed or variable 1:1 to 20:1

  • Viscosity Range: 10 to 3 million cps

  • Maximum Shot Size: Infinite

Flow Rate: MX3000 – 0.5 to 450 cc/min;MX4000 – 1 to 3000 cc/min

TYPES OF APPLICATIONS

  • Potting and encapsulation

  • Conformal coating

  • Form in place gasketing

  • Laminating

  • Sealing

  • Adhesive / assembly operations

  • Coating

MX1000/1500 Gear Pump Meter Mix Systems

 

PRODUCT DESCRIPTION

PVA’s MX1000 and MX1500 series rod displacement systems are ideal choices for meter-mix dispensing applications using heavily filled, abrasive materials. The rod displacement design eliminates metal to metal contact and does not contain wearable dynamic seals.

Closed loop servo drives enable the operator to program the mix ratio, shot size, flow rate, pressure control, vacuum degas, recirculation, and auto purge functions via a menu-driven HMI.

PVA’s rod displacement metering systems have many additional integrated features including:

 

  • Carbide rod for long life

  • Rugged steel frame eliminates tie rod design for easy set up and maintenance

  • Four carbide rod sizes available for superior resolution

PVA manufactures single and plural component metering systems customized to each specific requirement. Standalone metering systems not integrated onto a PVA robotic platform come with a standalone controller allowing multiple dispensing profiles to be stored. Within each profile, automatic purge modes and variable flow rates are available. PVA metering systems feature closed-loop servo drives for added repeatability and dispense volume accuracy.
