DEMA offers a number of different systems for industrial applications including high volume and drum dispensers. DEMA’s unique designs include reservoir mounted float valve systems for high output or large volume of diluted product storage. Auto scrubber and large reservoir fill-time is greatly reduced with high flow dispensers capable of 10 gallon per minute (40 liters per minute) capability. Also, a complete line of drum-mount dispenser models are available meeting standard and high induction requirements.

Brochure	Watch Guard Reservoir Mounted Float Valve Systems WATCH GUARD™ is the reservoir-mounted float valve system designed to cut service and maintenance costs. Watch Guard delivers reliable water valve activation every time with superior features for greater reliability. The float is filled with water soluble material instead of the standard system-clogging sand. The 90° chemical barb rotates 180° to ensure the chemical pick-up tube does not kink. And metering tips screw in, ensuring proper installation and no damage during maintenance. A number of different models are available for different fill rates and chemical induction.

	607-3 High Flow Dispensers The 607-3 High Flow Dispenser fills Auto Scrubbers and other large reservoirs at 10 gallons per minute (40 liters / min.) to reduce fill time over traditional dispensers. The 607-3 features a 1/4 turn ball valve activation and vacuum breaker for backflow protection. The stainless steel cover provides durability and large area for product identification. The system needs a 3/4” water supply and 10 gpm (38L) at 40 psi (2.8 bar) water flow and pressure to operate properly.
	161 & 162 Drum Mount Dispensers Model 161 and 162 Series drum mount dispensers mount to any 2 1/2” bung opening to dispense chemical solution directly from the drum or tote at the correct dilution. Various models are available to meet standard and high induction applications and multiple flow rates, and use metering tips or metering screw to deliver correct dilutions.   Model No. Maximum Induction Chemical Adjustment 161 1.5 to 1 Metering Screw 162 5 to 1 Metering Screw 162.3 5 to 1 Metering Tips 162HC 1 to 1 Fixed 162HDM.2 4 to 1 Metering Tips
