Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and thread specifications, so the bolt seats and torques correctly against the impeller hub without risk of stripping or misalignment.
- Direct-Fit Installation — Matches the original fastener dimensions exactly, threading straight into the impeller shaft without rework or modification to surrounding components.
- Broad Quick-Prime Trash Pump Coverage — Confirmed fitment across QP4TB, QP3THX, QP4TK, QP4TKT, QP3TK, QP2TK, QP3TS, QP3TH, and QP3TZ pump models.
- Impeller Retention Integrity — A correctly torqued impeller bolt keeps the impeller locked to the shaft at operating speed, maintaining consistent flow rate and preventing catastrophic impeller separation inside the volute.
- Critical Fastener Safety — In high-speed pump applications, fastener failure at the impeller can cause immediate pump seizure or internal damage; using the correct OEM-spec bolt is essential to safe pump operation.
The impeller bolt is the primary fastener that secures the pump impeller to the drive shaft. During operation, the impeller spins at high speed to generate the suction and discharge pressure that moves water and solids through the pump casing. If this bolt loosens, backs out, or fails, the impeller can shift or detach entirely, causing loss of pump output, internal casing damage, and potential shaft damage. Replacing a worn or damaged impeller bolt with the correct OEM part restores proper impeller retention and keeps the pump performing at its rated capacity.
