Rotation of rotor causes reciprocating movement of shuttle and piston.Single shaft design with long sleeve-bearing support and external ball bearing.Single gland construction reduces leakage to minimum.Front pull out design permits inspection of parts without disturbing the pipe connection, couplings or prime mover.Slow speed operation contributes to high reliability and less maintenance.Product is pumped without shear, foaming, agitating, heating, emulsifying or chewing.Pumping elements are of simple geometric form. Parts can be manufactured locally in any part of the world by a small repair shop.
