The Pacer P-58-1302-40 is a rear volute molded of gray polypropylene. The volute is the casing section that surrounds the impeller and guides the flow outward, so it sets how efficiently the pump builds pressure.
Pacer lists the same rear volute in black polyester, brown Ryton, and an IPW version, identified by the suffix. Choose the material that matches your pump and liquid, and inspect the volute for cracks, wear, and chemical attack whenever the pump is opened.
