The pump is filled with the solution in a temperature environment of 35 ° C and 2 ° C. After 8 hours, Placed 16h, according to this repeat five cycles. 3) After the test, the solution should be drained pump, over-flow surface with warm water, carefully check the corrosion. 4) The pump casing made of cast iron, cast aluminum, cast copper, other over-current components made of stainless steel, bronze or aluminum alloy and other highly corrosion-resistant materials pump, the above test may not be carried out.
