The Multiquip 0191190745 is a genuine OEM Bolt 7/16-20UNFX45 (Impeller) designed for the QP4TE trash pump. As a direct Multiquip OEM component, this bolt is manufactured to the exact thread pitch, grade, and dimensional specification required for secure impeller retention on QP4TE equipment. Sourced directly through authorized channels, 0191190745 ensures you are installing the correct hardware the first time. If you are servicing or rebuilding your QP4TE pump, verifying the correct impeller bolt is a critical step in restoring full pump output.
Key Features
- Correct Thread Specification — 7/16-20 UNF fine-thread form matches the impeller mounting thread exactly, ensuring full torque capacity without cross-threading risk.
- Genuine OEM Hardware — Manufactured to Multiquip's material and hardness specifications for impeller fasteners, so clamping load is maintained under pump vibration and hydraulic loads.
- Direct-Fit for QP4TE — Engineered specifically for QP4TE trash pump impeller assemblies; installs into the existing bore without modification.
- Impeller Integrity Under Load — A properly torqued impeller bolt keeps the impeller centered and locked to the shaft, sustaining consistent flow rate and pressure throughout the pump's operating range.
- Built for Demanding Pump Applications — Trash pump impeller fasteners are subject to continuous vibration and fluid-induced axial loads; OEM-grade bolt material resists fatigue loosening in these conditions.
The impeller bolt secures the impeller — the rotating vane assembly responsible for drawing water and solids into the pump and expelling them through the discharge — directly to the pump shaft. If this bolt is loose, corroded, or improperly torqued, the impeller can shift axially or spin out of balance, causing a rapid drop in flow performance, increased wear on the volute and seal faces, and potential shaft damage. Replacing a worn or damaged impeller bolt with the correct OEM part, Multiquip 0191190745, restores proper impeller clamping and protects the broader pump assembly from secondary wear.
