PD44 Dispensing System A unique Patented Technology for Micro Dispensing Two-Component Materials P R O V E N Q U A L I T Y. L E A D I N G T E C H N O L O G Y.

2 The PD44 is specifically designed to dispense small amounts of water thin to paste viscosity materials from 0.005cc’s to 5cc’s. The metering rods are matched with machined seals for improved seal life. There are no material hoses between the rod pump outlets and mixer inlet which eliminates potential ratio or shot size problems (phasing) due to hose expansion and contraction.

3 Materials remain separate until injected into static mixer The patented PD44 valve features balanced inlet/outlet spool assemblies that do not displace material while shifting from the reload to the dispense position. This allows pressure feeding of the “A” and “B” components up to 1200 psi during reloading while isolating the materials from the mixer inlet. Upon shifting to the dispense position without any material displacement, an accurate volume of “A” and “B” components is injected into the disposable mixer inlet by rod displacement metering technology. Reload Spools shift to the right...

6 Complete System PD44 with pneumatic controller, manual micrometer shot adjuster and dual one gallon transfer pump feed package. Systems Cartridge Feed Systems Cartridges of various sizes can be placed in pressurized retainers to allow low to medium viscosity materials to transfer to the PD44 valve. Transfer Pumps and Rams Low to high viscosity materials can be pumped directly from bulk containers using pail and drum rams, transfer pumps and feed hoses as required. Reservoir Tanks Various sized reservoir tanks can be used to transfer low to medium viscosity materials to the PD44 valve. Feed...
