 Application: Control of plant air to air operated diaphragm pump (Warren Rupp Flap-Valve SA1-A Sandpiper) to control discharge of pump in coiled steel coating process.
Where In Process?: Plant compressed air line to sludge press feed pump after pressure regulator.
Why Flow Rate is Critical?: Plant compressed air line to sludge press feed pump after pressure regulator.
What Alternatives Were Considered: Pressure regulator and control valve.
Main Reasons for Choosing Kates: Kates is required to control air flow for a constant discharge rate regardless of the back pressure fluctuations of the pump. Variability of air flow is needed to determine different pumping rates.
