The Multiquip 0191190732 is a genuine OEM Impeller Bolt 7/16-20 UNF x 32 designed for QP3TY, QP3TH, and QP3TE series trash pumps. As a direct OEM replacement, this bolt is manufactured to the exact thread specification and dimensional tolerance required for proper impeller retention. Sourced directly through an authorized Multiquip parts channel, 0191190732 ensures a correct, secure fit with no guesswork on thread pitch or length. DHS Equipment stocks this part to keep your pump running at full capacity with the hardware it was built around.
Key Features
- Correct Thread Specification — Machined to 7/16-20 UNF x 32 spec, matching the exact thread pitch and engagement length engineered for the impeller assembly.
- Genuine OEM Component — Sourced from Multiquip's authorized parts supply, so the bolt meets the same material and hardness standards as the original fastener installed at the factory.
- Direct Fitment for QP3 Series Pumps — Confirmed fit for QP3TY, QP3TH, and QP3TE trash pumps; drops into place without modification to the impeller hub or shaft.
- Impeller Integrity Under Load — A correctly torqued impeller bolt keeps the impeller locked to the shaft during high-volume pumping cycles; a worn or incorrect bolt risks impeller wobble, reduced flow, and accelerated wear on the pump housing.
- Single-Hardware Fix — When an impeller bolt strips, backs out, or shears, replacing it with the correct OEM fastener (0191190732) restores full pump function immediately without replacing larger components.
The impeller bolt is the critical fastener that secures the pump impeller to the drive shaft inside the pump casing. It holds the impeller at the precise axial position needed to maintain the centrifugal force that moves water and solids through the pump body. If this bolt loosens, strips, or fails, the impeller can shift or spin freely on the shaft, causing a sudden loss of pumping pressure, potential damage to the volute casing, and internal wear that can compromise the entire pump assembly. Replacing a damaged or missing impeller bolt promptly with the correct OEM part is one of the simplest ways to restore full pump output and prevent a minor fastener issue from escalating into a major repair.
