ProMix PD Plural Component Mixing and Fluid Control
The ProMix Positive Displacement (PD) Proportioner Platform is redefining fluid control, plural component mixing and manufacturing processes. Stay on ratio within 1 percent mixing accuracy. Stay on budget with less rework and simple maintenance.
BENEFIT FROM PLURAL COMPONENT MIXING
Take advantage of the benefits of plural component material with our unique positive displacement pump system.
- True volumetric control: The electronic fluid control system can operate in both flow and pressure mode, with high and low pressure options.
- Versatility and flexibility: Operate up to four pumps, dispense different chemistries, and track pot life for up to three spray guns – all on one system. You also can manage up to 30 colors, four catalysts, and typically separated materials (e.g. epoxy/urethane, metallic/non-metallic, waterborne/solvent borne).
- Low flush technology: Moving the mixing point closer to the gun decreases the flush zone and increases efficiency. It also reduces solvent use and material waste by up to 80 percent.
- Air/solvent chop: Patented features allow you to preset flushing routines for different materials.
- Intuitive controls and display: Easy-to-navigate screens guide you through operation, setup, and troubleshooting. See real-time data on system parameters.
- Automatic and manual configurations: The ability to upgrade parts in the field at any time allows you to start with a manual single pump system and then move to a multiple pump automatic system.
Higher accuracy
The ProMix PD guarantees a mixing ratio accuracy within 1% thanks to its unique encoder-based piston drive technology and active control valves, ensuring smooth and exact dispensing every time. It maintains this exceptional accuracy regardless of head pressure, elevation, material viscosity, temperature or gun triggering.
Faster flushing
By moving the mixing point closer to the gun, Graco’s ProMix PD decreases the flush zone, which means less material waste, faster flushing and increased efficiency. Full flushing can be programmed in the ADM, with the option to preset up to five different flushing recipes with individual solvents, time schedules and other factors.
Reduced costs
Save money thanks to the ProMix PD’s unique characteristics: less rework and unbeatable reliability based on impeccable flow control, quick colour changes and better dispensing. Its unique flushing method reduces solvent use and material waste by up to 80% and the cost of maintenance is significantly lower compared to gear pumps.
Increased flexibility
The ProMix PD is perfectly suited for manual or automatic applications. Operate up to four pumps, dispense different chemistries and track pot life for up to three spray guns on one single system. Manage up to 30 colours in 1K to 4K setups and combine typically separated materials like epoxy and urethane or waterborne and solvent-borne paint.
A closer look at the Promix PD
High performance coatings need high performance equipment. Our versatile ProMix PD product line lets you enjoy the many benefits of plural-component mixing, such as higher accuracy, shorter curing times and less material waste.
Fully customised to your needs
With our wide range of configurations and options, we are able to meet any component or material chemistry requirements. Tailored to your needs and custom-built with high-quality Graco components.
Evolves with your business context
Upgrade or switch system components at any time. Want to start off with a manual single setup and evolve towards a multiple-pump automatic setup? No problem at all.
Automatic configuration
Efficiency and performance are at the heart of our Automatic ProMix PD technology. Not only do our systems provide connectivity to your network for greater efficiency and control, the Automatic ProMix PD line outperforms many other proportioners in its class.
Solutions are available for regular or integrated setups:
Regular
- Compatible with all kinds of applicators
- Limited monitoring and steering options
- Paint triggered via network or discrete I/O
- Mixing recipes via programmed ADM, PLC or other input
integrated
- End-to-end solution
- Monitoring and steering with Graco software (incl. regular upgrades)
- Paint triggered via programmed ADM, PLC or other input
- Mixing recipes via air control module, PLC or other input
Integrated air control box for maximum efficiency
If you opt for an integrated automatic setup, the integrated Air Control Module provides electrical and air connections to enable the ProMix PD system to operate two spray devices, as well as one or two gun flush boxes or one or two air shutoff valves.
Maintain constant flow rates using positive displacement
Positive displacement technology gives the unique ability to deliver a constant fluid flow rate and pressure, regardless of fluid properties. This feature allows the pump to stall under pressure. Constant pressure is guaranteed by preset values, which prevents misadjusting by operators and eliminates the need for regulators in the mixed material fluid stream. Additionally, the constant pressure level allows for a fast response to changing conditions.
Control the process from a to z from the booth
The compact and easy-to-use booth control provides a safe and efficient way to control recipe, pressure and colour changes, all from inside the spray booth. No need to lose time or switch off the system for simple changes.
Dose pumps for incomparable accuracy
The ProMix PD can operate up to four different pumps, dispense different materials and manage multiple applicators on the same system. Because dose pumps are not sensitive to wear, they are an excellent way to avoid material slippage, ensuring an incomparable mixing ratio accuracy within 1 percent. As seals can be replaced in the field in minutes, the pump's maintenance cost is very low compared to other technologies.
Remote mixing thanks to hose bundle
The hose bundle conveniently combines multiple-coloured hoses – for solvents, catalysts, colours and air – in a single hose connected to the booth. This means the mixing point can be moved much closer to the spray gun.
Efficient flushing with the air/solvent chop
Air/solvent chop allows for customisable flushing recipes that use air and solvent chop (short bursts of air or solvent to flush the system) through the pump. This reduces solvent usage during flushing and reduces the time required to fully flush the pump.
Manual configuration
Manual painting with Graco ProMix PD is as efficient as you can get without going automatic. This technology allows you to limit material waste, control pressure and experience less operator error. It’s your familiar spray gun setup, but monitored by an efficient and highly accurate system.
Maintain constant flow rates using positive displacement
Positive displacement technology gives the unique ability to deliver a constant fluid flow rate and pressure, regardless of fluid properties. This feature allows the pump to stall under pressure. Constant pressure is guaranteed by preset values, which prevents misadjusting by operators and eliminates the need for regulators in the mixed material fluid stream. Additionally, the constant pressure level allows for a fast response to changing conditions.
Add extra colours with the colour change module (optional)
The ProMix PD system can manage up to 30 colours and four catalysts thanks to the optional colour change module and its corresponding valve stacks.
Convenient advanced display module
Make the operator’s life easy thanks to easy-to-navigate screens that guide users through operation, setup and troubleshooting. Our system provides real-time data on system parameters to help you avoid any costly errors. You can access all the data through a PLC or download it using the USB port to optimise processes or make improvements.
Save time and material with the remote mix manifolds
The ProMix PD system is compatible with Wall Mix manifolds for automatic colour switch or Belt Mix manifolds for manual colour switch, carried in hand or mounted to a robot. This reduces not only colour change time, but also flushing, material waste and downtime. Faster colour change means increased throughput and productivity. The ability to load multiple guns on one system means that colour change time can be eliminated.
Single or dual mix: adapt the system to your needs
The PD Dual Mix unit does the job of two systems for maximum production flexibility. Control two guns in one booth at the same time or control two painters in two separate booths with the option to use one or both mix units depending on production needs or maintenance schedules. Dual systems allow you to change colours instantly.
