<p>A progressing cavity pump adapted for use in pumping liquid/solid mixtures with a solid content of about 50% has a single start helical rotor and a two start helical stator bore. The ratio of the eccentricity of the rotor to its minor diameter is about 1:4.9. The ratio of the eccentricity of the rotor to the stator lead is about 1:13.3. The pump may be truck mounted and used for pumping explosives. <IMAGE></p> |
