The Multiquip 0191150625 Impeller Bolt 3/8-24 UNF x25 is a genuine OEM fastener designed for MQ series trash pumps. This bolt secures the impeller directly to the pump shaft, making thread specification and torque integrity critical to safe, leak-free pump operation. As a genuine OEM component, the part is manufactured to the exact thread pitch and length required for correct installation. Confirmed fitment for QP40TH and the broader MQ trash pump family means you can order with confidence.
Key Features
- Exact Thread Specification — Machined to 3/8-24 UNF thread standard, ensuring full thread engagement and proper torque retention at the impeller shaft interface.
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specification, maintaining the mechanical integrity the impeller assembly depends on.
- Direct Replacement for MQ Trash Pumps — Confirmed fit for QP40TH and compatible MQ trash pump models; installs in place of the original bolt without modification.
- Impeller Security Under Load — A correctly torqued impeller bolt keeps the impeller centered and locked during high-volume pumping cycles, preventing wobble, cavitation, and shaft damage.
- Safety-Critical Fastener — An impeller bolt that is stripped, under-torqued, or incorrectly threaded can allow the impeller to loosen during operation, creating a hazard and causing immediate pump failure.
The impeller bolt is the fastener that locks the pump's impeller onto the drive shaft, holding it securely in position so it can move water efficiently under load. If this bolt is loose, cross-threaded, or the wrong specification, the impeller can shift or detach during operation, which leads to loss of prime, internal damage to the pump housing, and potential shaft failure. Using the correct OEM-spec bolt — with the right thread pitch, length, and material grade — is essential to keeping the impeller seated and the pump performing reliably through demanding trash-pumping applications.
