Abstract
A pumping apparatus 10 for dispensing multiple component fluid material. The apparatus 10 includes at least first and second flexible tubes. The tubes each have an inlet and an outlet, and each of the inlets is supplied with a different component of the fluid material. A roller or rollers are provided for pressurized engagement with the tubes. The stop plate is engaged with the tubes at a location opposing the pressurized engagement of the roller. A driver mechanism independently moves the roller in pressurized engagement with the tubes, opposed by the stop plate, in a linear direction. Such linear movement carries the desired and variable amounts of fluid material to the tube outlets. An engagement frame supports the tubes, roller, stop plate and driver mechanism. A mixing reservoir is provided having multiple inlets, each of which is engaged with a flexible tube outlet, and a single outlet, such that the fluid material components are combined within the mixing reservoir and provided to the single outlet. A static mixer may also be provided which is supplied with mixed fluid material via the single outlet of the mixing reservoir for further mixing of the components of the fluid material.
