ABSTRACT:
The liquid pressure capacity of a chemical injector pump is increased substantially by using high pressure gas to drive the gas motor. In one embodiment, the chemical injector pump includes a liquid pump end, a gas motor end, a low pressure position responsive valve, and a high pressure pilot operated valve manipulated by the low pressure valve for delivering high pressure gas to the gas motor. In other embodiments, the chemical injector pump includes a liquid pump end, a gas motor end, and a high pressure position responsive valve for directly delivering high pressure gas to the gas motor.
