Fig. 3From: Effects of metal corrosion in the pump of a dialysis machine on the sterility of the terminal dialysate by spike-and-recovery testing with bacteriaMetal corrosion on the used magnet gear pump parts made by SUS 316. (a) Front plate and (b) gear case. Photos on the left and right represent the front and rear sides, respectively. “Used parts” refers to parts of a pump that had been used routinely in a clinical environment for 10 months.
