ST-62 ADJ. CHEMICAL INJECTOR, 2-8GPM

The ST-62 injector allows for water flow adjustment from the pressure pump. By adjusting the water flow through the ST-62, a restriction causes a vacuum which allows the detergent to be drawn through the hose barb when a large orifice nozzle is used. With the adjustment feature, the ST-62 can be used with a variety of water flows, replacing injectors with fixed orifices that are sized to specific flows.

INJECTOR RATIOS:

• Injector ratios are approximate
• They vary with the lift required, downstream restrictions, viscosity, temperature, etc
• To determine the exact siphon ratio for your application: (1). Operate the injection feature for one minute
• (2). Measure how much detergent was used
• (3). Subtract the amount of injected detergent from the total amount of liquid discharged
• (4). Divide this number from the amount of injected detergent. EXAMPLE: If the total amount of liquid discharged equals 5 gallons, and the detergent injected equals 58 oz.(0.45 gal.), the exact ratio woild be determined as follows: 5.0 -0.45=4.55 divided by 0.45=10. The ratio is 10 parts water to 1 part detergent.
