Page 4: Introduction
Dymax SG-200 High-Flow Spray Gun System User Guide Introduction Introduction to the User Guide This guide describes how to use Dymax SG-200 spray gun systems. These systems are comprised of an SG-200 spray gun used in conjunction with any one of the following reservoirs: ■... -
Page 5: Specific Safety Considerations
To learn about the safe handling and use of dispensing fluids, obtain and read the Material Safety Data Sheet and handling requirements for each fluid before using the fluid. Dymax includes a Material Data Safety Sheet with each adhesive we sell. You can also request Material Safety Data Sheets for our products on our website. -
Page 6: Overview Of The Spray Gun System
How the Spray Gun System Works The Dymax SG-200 spray gun system uses compressed air to pressurize the fluid reservoir. The pressure pushes fluid from the reservoir through the fluid line to the handheld spray gun. A satellite controller is used to control valve actuation. - Page 7 Spraying begins when the operator squeezes the trigger and stops when the trigger is released. The atomizing function on the SG-200 is an “always on” mode, ensuring the heaviest materials atomize upon dispense. The spray gun includes a kit of caps and nozzles of different diameters, allowing users to adjust per flow rates and materials being sprayed.

Page 9: Types Of Reservoir Retainer & Tanks
Dymax SG-200 High-Flow Spray Gun System User Guide Types of Reservoir Retainer & Tanks Depending on the dispensing system you ordered, your system includes: ■ Cartridge reservoir retainer - for high-flow delivery to small or hard-to-access applications ■ Bottle/pail reservoir tank - for applications requiring volume delivery of low/medium-viscosity materials over large areas ■... - Page 10 Dymax SG-200 High-Flow Spray Gun System User Guide Bottle Reservoir Tank The bottle reservoir tank includes a push-through fitting on the tank cover. You push the fluid dispensing line through the fitting and into the tank to form a dip tube. When the tank is pressurized, the fluid is pushed up the dip tube and into the fluid dispensing line (Figure 3).

Page 11: Pail Reservoir Tank
Dymax SG-200 High-Flow Spray Gun System User Guide Pail Reservoir Tank The pail reservoir tank includes a metal dip tube with an outlet fitting on the tank cover. If desired, you can configure the dip tube as a flexible tube using the supplied dispensing line by pushing the line through the supplied push-through fitting. -
Page 12: 5-Gal Ram Pump System
Also included in the high-pressure configuration is a length of stainless, braided hose with compression swivels and fittings to maximize throughput while extending flexibility to the operator. As a system, the SG-200 and ram pump system provide a solution for high-flow, high-viscosity delivery beyond the capabilities of standard pneumatic reservoirs. -

Page 15: Initial Setup Of The Spray Gun
Connecting the Air Filter/Regulator 1. Check to make sure the dual tubes from the atomizing head on the front of the SG-200 valve is connected to the dual port of the atomizing control regulator. The air line between the atomizing control regulator and material pressure regulator should also be pre-configured. -
Page 16: Connecting The Dvc-345 Controller
Dymax SG-200 High-Flow Spray Gun System User Guide Connecting the DVC-345 Controller 1. Locate a convenient, clean position to place the controller. NOTE: If using a spray booth or environment where electrical devices are forbidden, position the controller outside of the immediate environment. -
Page 17: Connecting The Material Reservoir
1. Unscrew the cover from the cartridge reservoir retainer. Remove the empty cartridge reservoir if present. 2. Remove the plastic cover from the top of a Dymax or other cartridge reservoir. 3. Place the cartridge reservoir in the retainer so that the fluid outlet at the bottom of the cartridge extends through the hole in the bottom of the retainer. - Page 18 The dispensing system will not function properly if you plumb the compressed air lines incorrectly. WARNING! Some Dymax fluids can bond skin together in seconds. It can also irritate skin, eyes, and mucous membranes. To minimize the risk of bonded skin or irritation, wear protective gloves and eyewear when working with Dymax fluids and the hand-held spray gun system.

- Page 20 Dymax SG-200 High-Flow Spray Gun System User Guide Fluid Line Connections 1. Determine the working length of the dispensing line from pail tank to the spray gun and cut the line to length. The fluid line should be cut as short as possible to reduce pressure losses in the line, but long enough to enable you to reach and work comfortably with the spray gun in the work area.

Ensure all connections are tight. NOTE: Use Teflon®/sealant tape on all straight connector and fitting threads. For best performance, keep the hose lengths as short as possible and ensure tight connections between fittings.
- Page 23 Dymax SG-200 High-Flow Spray Gun System User Guide 9. Turn on the ram pump. Do NOT turn on the atomizing switch. Aim the SG-200 spray gun away from people and unintended target objects. Purge the material into a container vessel by depressing the spray gun trigger.

Page 29: Cleaning And Maintenance
To switch your system over from dispensing one fluid to dispensing a new fluid, determine if the fluids are compatible with pump and valve components. If you are uncertain about material compatibility, contact Dymax Application Engineering for assistance. If the fluids are compatible, replace the fluid tubing and clean the dispensing valve and spray cap. - Page 30 Dymax SG-200 High-Flow Spray Gun System User Guide 1. Begin disassembly by removing air and fluid pressure from the valve. 2. Remove all pneumatic tubing and fluid delivery fittings, hoses, etc. from the valve. 3. Using the tip of a 3/32” Allen key, loosen the packing nut (6).
