CHEMICAL INJECTORS

ST-60 CHEMICAL INJECTORS (downstream)

The ST-60 is a downstream chemical injector that relies on a
pressure drop that is created by using a larger orifice spray nozzle.

• Siphon rate approximately 10:1.
• Forged brass housing, stainless steel spring and ball.
• 4 ft clear hose available, #900000041.
• Fixed flow rate for accuracy.
• 1/2” hose barb.

ST-62 ADJUSTABLE CHEMICAL INJECTOR (downstream)

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.
