Abstract
Integrated, stand-alone, multiple-purpose pump stands are provided for controlled pumping of different liquids from a stand-mounted tank to a downstream use location, e.g., a seed treating device. The pump stands are equipped with an operating assembly including a liquid tank, a powered pump, a liquid flow line equipped with a flow meter from the tank and pump to the use location, and a programmable digital control device. During operation, the control device serves to approach and maintain the flow rate from the pump stand at or about a desired setpoint flow rate.
