| IRON
PUMP SÉRIES 33, 53 and 63
THE POWER OF THE IRON
 The Hydraulic Gear Pumps and Motors Bushing Series, are produced in single or multiple units, projected
especially for application that demand greater pressures and rotations, providing one better volumetric
efficiency, bigger pressures of work and low index of noise. Three-piece cast iron construction are
assembled with a Main body, Mounting Flange and End cover, in form of segmented, what it allows a good
assembly variation.
Low-Friction bushing provides high efficiency, and long life in severe operation environments, constructed
in metal with covering of Teflon (P.T.F.E.), what a certainty of lesser consuming with consequent increase of
the useful life confers it. Advanced Thrust Plate and seal configuration, which optimizes performance even
in high temperature, shafts and gears manufactured with special and treated steel, with finishing in the
polishing sliding parts.
In the following pages, you it will be able to find a variety of types of Shafts and Flanges that can be
combined between them.
