Abstract
The present invention discloses operation of a system for injecting a predetermined amount of a secondary fluid into a primary fluid stream. The system uses a liquid additive injection pump driven by a fluid powered motor that is driven by the primary fluid stream and can be selectively suspended by an automated switch mechanism. The automated switch mechanism comprises an actuator in communication with an actuating shaft and a fluid source. When the actuator is pressurized, an actuating shaft is displaced relative to a housing which either engages or suspends the fluid-powered motor.
