Abstract
An apparatus and method for pumping high viscosity mixtures, for example silicone-aggregate mixtures, including a pump and a hose, wherein the hose is impermeable, nonadherent with the mixture, and resistant to swelling, and the pump and the hose are sealable. In preferred embodiments, the apparatus and method can include a metering mechanism for dispensing the mixture to the pump, an agitator for mixing the mixture before it enters the pump, and a spray nozzle for applying the mixture exiting the hose. Even more preferred embodiments can include a metering mechanism in the form of a variable speed auger screw, a hose internally lined with a coating of polytetrafluoroethylene, a hose structurally reinforced, and a pump and hose that are individually sealable.
