I am using this as a coolant injection pump in a machining process. It is being controlled by a PWM micro controller to feed coolant into a high pressure air stream (125 psi). It has been online for about a week and is performing as expected.
Exact replacement for my last one that lasted almost 9 years. The head unit cracked on my last one likely due to subfreezing weather. Will likely just replace the head on it and have a spare. Great pump, and always worked flawlessly on my AEM water/meth injection kit.
