The Pentair C105-137PDBA is the OEM replacement impeller assembly for the Sta-Rite Max-E-Glas and Dura-Glas single-speed pump series — now manufactured and supported under the Pentair brand following Pentair's acquisition of Sta-Rite. IMPORTANT: VERIFY YOUR PUMP MODEL BEFORE ORDERINGThis impeller fits specific Max-E-Glas and Dura-Glas models only. Confirm your pump's model number against the compatibility list below before placing your order. Using an incorrect impeller will result in reduced flow, motor overload, or pump damage. The impeller is the rotating component inside your pump that draws water through the strainer and pressurizes it toward the filter and return system. A worn, cracked, or clogged impeller causes a direct loss of flow rate and system pressure. Replacing it with the correct OEM assembly restores the pump to its rated performance specification.

This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Pro Tip When replacing the impeller, inspect the shaft seal and diffuser at the same time — these components wear together and replacing them as a set during the same service call prevents a second teardown within the same season. Always confirm the impeller spins freely by hand before reassembling the pump housing.
