An apparatus and process are provided for mixing and dispensing high viscosity, multiple component reactive liquids into a mold. The apparatus and process are particularly suitable for mixing and dispensing highly viscous intumescent fireproofing materials. Each reactive liquid component is stored in a separate pressure tank. The liquid components flow through separate conduits leading from each pressure tank, and are metered by a gear pump located in each component conduit. A gear linkage synchronously links the gear pumps together, and a self-locking motor is adapted to drive the linked gear pumps. When the motor is turned off, the gear pumps act as a valve to stop flow of the component liquids. The metered components flow into a common conduit, which has therein a static mixer for thoroughly mixing the components. The mixed components are then dispensed through an orifice. This orifice can be directed to the bottom of the mold so that the mold can be filled with the highly viscous material from the bottom to reduce the formation of air voids.
