We offer a complete product range of Aluminum Pump Cavitation Corrosion Tester
ApplicationThis test method covers the evaluation of the cavitation corrosion and erosion-corrosion characteristics of aluminum automotive water pumps with coolants
MethodThis test method consists of pumping an aqueous coolant solution at 113°C (235°F) through a pressurized 103-kPa (15-psig) simulated automotive coolant system.
An aluminum automotive water pump, driven at 4600 r/min by an electric motor, is used to pump the solution and to serve as the object specimen in evaluating the cavitation erosion corrosion effect of the coolant under test. The pump is examined to determine the extent of cavitation erosion corrosion damage and is rated according to the system given in Table Photographs of typical eroded pumps after testing Appear in the Appendix
UsesThis test method can be used to distinguish between coolants that contribute to cavitation corrosion and erosion corrosion of aluminum automotive water pumps and those that do not. It is not intended that a particular rating number, as determined from this test, will be equivalent to a certain number of miles in a vehicle test; however, limited correlation between bench and eld service tests has been observed with single-phase coolants. Field tests under severe operating conditions should be conducted as the nal test if the actual effect of the coolant on cavitation corrosion and erosion-corrosion is to be appraised. It is also possible, with proper control of the test variables, to determine the effect of pump design, materials of construction, and pump operating conditions on cavitation corrosion and erosion-corrosion damage
