METHOD AND APPARATUS FOR ACCURATELY DISPENSING LIQUIDS AND SOLIDS

摘要

A system for metering and dispensing single and plural component liquids and solids. The dispensing system maintains constant pressure between the output of the pump and the dispense head. The progressive cavity pump is formed from individual, interlocking pressure sections (140), each of which has a double helix bore (139). A rotor (141) is inserted into the double helix bore with an interference fit.
