VOITH Liquid Ring Vacuum Pump Repaired and Coated with CPR Material
CUSTOMER: A papermill in Ontario
APPLICATION DATE: March 2003
PROBLEM: Normal operation had caused corrosion damage plus wear & tear on this liquid ring vacuum pump. Pump casing had actually holed through and OEM pump tolerances were gone in critical areas of vacuum pump including rotor and cone gap.
SUBSTRATE: Cast Iron
APPLICATION METHOD: After thorough surface preparation CPR repair composites and protective coatings were applied, formed and machined according to proven CPR application technologies. All OEM tolerances were restored.
CPR FACTS: This repair was less expensive and time consuming than replacement or exchange option
