Cleaning Hydraulic Pump Bodies / SG iron

Process for cleaning Hydraulic Pump Bodies:

Galvex 17.30 provides both cleaning and anti corrosion protection in one stage, and has very good rinsing properties. This allows us to use an additional DI water rinsing stage with a very concentrated anti corrosion product called Korrostop 5000 to ensure no oxidation. The bath was filled with tap water and diluted with a 3% concentration of Galvex 17.30. The bath was allowed to heat up to the required temperature of 80°C and degassed for 10 minutes.

The part was placed inside a Halar coated basket with the lapped face down. This coated basket will ensure no metal on metal marks are left on the lapped face. By positioning the contaminated area towards the ultrasonic cavitation we ensure optimal results.

Cleaned for 5 minutes in Galvex 17.30 then rinsed in a static tap water bath for 1 minute to remove the soapy residue. Next the part was rinsed in the additional DI water rinse tank with the Korrostop anti corrosive agent for 3 minutes. Lastly the part was dried as before for 5 minutes at 90°C, flipping over to allow the pooling water to escape then back in for anther 5 minutes.

Results: Visually good with no signs of any lapping residue and no oxidation.
