Abstract: A rotary pump plural component applicator apparatus is provided for dispensing plural components, such as resins and adhesives or the like, with an activator for the resins or adhesives. A plural component applicator uses an electric motor gear box driving first and second rotary pumps. The use of an electric motor driving plural rotary pumps improves the plural component applicator performance in the application of the plural components.

Abstract: A melter, mixer and applicator system for applying coating or sealing compositions is disclosed. An internal combustion engine, such as a diesel engine, is used to provide the motive force necessary to operate many or all of the components of the system. A tank surrounded by an internal heating system is provided for melting a first material, such as asphalt. An insulated cabinet is provided and heated from heat generated by the internal heating system. The plumbing configuration for the system is disposed within the heated cabinet for mixing the material heated within the tank with an additional material fed to the plumbing configuration by a proportioner pump. The output of this mixture serves, through a heated hose, as one of the inputs to the applicator, which is preferably a plural component spray gun. The other input to the applicator is another material fed directly from the proportioner pump.

Abstract: An applicator is provided which through the use of valve assemblies and separate first and second tubing member delivers two separate materials separately to a mixing head. The mixing head is provided with two separate passageways which terminate into an outlet passageway. To help create equal pressure between the materials at the point where the materials meet, an impinger can be placed in one or both of the mixing head passageways. Material flowing into each mixing head passageway first meet and are mixed in the outlet passageway. A tip is attached to the mixing head and a static mixer can be disposed within the tip for further mixing of the combined materials prior to their application out of the tip onto the intended surface. Material is supplied to the valve assemblies by various methods such as hoses. A spray gun embodiment is also disclosed.
