Hydraulic pump/motor flange cover adapted to prevent contamination, machine surface damage and corrosion

Abstract

A pulp paper formed flange cover is provided. The pulp paper flange cover is adapted for protecting hydraulic motor/pump housing ports and openings, and surrounding surfaces. The flange cover may be infused with corrosion-preventive chemicals to protect the housing from corrosion. Additionally, the flange cover protects the housing surface from damage while preventing infiltration of the openings of the housing by contaminants.

What is claimed is: 
     
         1 . A method of making a flange cover for a hydraulic motor and or pump housing, comprising:
 forming a mass of pulp paper in such a way that a flange cover results, wherein the flange cover is dimensioned to engage a flange of said housing along an outer surface thereof and occupy at least one port in said flange.   
     
     
         2 . The method of  claim 1 , further comprising:
 infusing said flange cover with a corrosive preventative chemical.   
     
     
         3 . A flange cover for a hydraulic motor and or pump housing, comprising:
 pulp paper formed in such a way so as to engage a flange of said housing along an outer surface thereof and occupy at least one port in said flange.   
     
     
         4 . The flange cover for a hydraulic motor and or pump housing of  claim 3 , further comprising a corrosive preventative chemical infused in said pulp paper.
