The Pacer P-58-0683-40 is a gray polypropylene impeller listed by Pacer for the A and I Series pumps. Polypropylene gives good resistance to many acids and bases, which is why it is used in chemical-handling pumps.
A worn or damaged impeller causes weak flow, low pressure, or noise. When you replace it, check the shaft seal and clearances at the same time, and confirm the part number against your pump plate because Pacer builds several impeller sizes.
