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

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.

SPECIFICATIONS:

• Flow rate: Adjustable 2 to 8 GPM
• Maximum pressure: 3600 PSI
• Forged brass housing
• Viton o-rings
• Stainless Steel spring and ball
• Inlet 3/8" FPT
• Outlet: 3/8" FPT
• 1/4" Hose barb

MOUNTING AND OPERATING INSTRUCTIONS:

• (1). Connect the discharge port of the cleaner to the inlet port of the injector. (the arrow on the injector housing should point in the direction of the water flow)
• (2). Connect dwonstream components, such as discharge hose and gun, to outlet port
• (3). Connect the detergent hose to the hose barb and secure
• (4). Place the other end of the hose into the detergent
• (5). Turn on the water. On the ST-62 also turn adjustment to maximum counter clock-wise
• (6). To activate injector, employ the large orifice nozzle. The ST-62 will now need to be adjusted clockwise for detergent suction.

Thank you for browsing our selection of pressure washers, steam cleaners and accessories.

We have the tools you need to effectively use and maintain your pressure washer.  Quick connect and rotating turbo nozzles are available in various sizes and configurations.  It's important to use the proper size nozzle for your pressure washer.  Nozzles are sized by looking at the PSI and GPM of your pressure washer.  Quick connect nozzles make it easy to change spray patterns or replace nozzles when they are bad while using the same spray wand.

Pressure washer hoses and hose reels will help you reach your work area, and specialized spray guns with different angles and lengths of wands will make certain jobs easier.

To keep your pressure washer working properly, routine parts and maintenance could be required.  Pressure washer pumps, unloaders, and motors should match the specifications of your particular machine.  Hot pressure washers and steam cleaners require additional components like burners, ignitors, and fuel pumps to allow them to heat the water.

There are a number of different accessories for your hot or cold pressure washer to clean different areas.  Surface cleaners are great for cleaning large areas like parking lots, gas stations, industrial facilities, and school yards.  Duct cleaners are designed to clean trash-chutes, vents, ducts, restaurant hoods, tanks and more. Wet sand blasters can be used on various surfaces to remove most coatings down to white metal, for graffiti cleaning, or paint surface preparation.
