Abstract
A paint circulation pump control system having a plurality of pneumatic or hydraulic pump assemblies that operate at different outputs in response to load changes on a paint application system is provided. Each pump assembly includes a first regulator and second regulator having different pressure output settings selectively connecting a compressed air source with a pump. A control valve in each pump assembly is responsive to a single switch to connect the compressed air source to the pumps via the first or second regulators. When the switch directs a change, all of the pump assemblies simultaneously change the regulator that is connecting the pump with the compressed air source.
