The Multiquip 0151191257 is a genuine OEM Stud Bolt (Drain Cover Handle) M12 X 57 X15 X 22 designed for Multiquip QP-series trash pumps and centrifugal pumps. As a direct OEM replacement, part 0151191257 meets the original engineering specifications, ensuring correct thread engagement and secure clamping at the drain cover. Confirmed fitment includes the QP2TH, QP3TH, QP3THX, QP2TK, QP3TK, QP3TS, QP2TZ, QP3TZ, QP3TB, and QP2TB — covering a broad range of Multiquip quick-prime pump models. Sourced directly through authorized distribution channels, this part is backed by Multiquip's OEM quality assurance.
Key Features
- Genuine OEM Thread Specification — M12 x 57 x15 x 22 dimensions match the original stud exactly, so thread engagement depth and clamping load are correct from installation.
- Drain Cover Integrity — A correctly torqued stud bolt holds the drain cover firmly against its seat, preventing leaks and maintaining pump prime during operation.
- Drop-In Installation — Threads directly into the existing drain cover boss with the same pitch and shoulder dimensions as the original hardware — no rework needed.
- Broad QP-Series Compatibility — Fits QP2TH, QP3TH, QP3THX, QP2TK, QP3TK, QP3TS, QP2TZ, QP3TZ, QP3TB, and QP2TB pump models in one part number.
- Corrosion-Resistant Hardware Grade — Built to withstand the wet, abrasive environment of trash and centrifugal pump service where drain hardware is routinely exposed to water and sediment.
A stud bolt at the drain cover handle anchors the cover against the pump casing, creating a sealed closure that keeps water from bypassing the volute during operation. When this stud is damaged, stripped, or missing, the drain cover cannot be secured properly, leading to leaks, loss of prime, and potential contamination of the work area. Replacing a worn or compromised stud bolt promptly restores a leak-free seal and allows the pump to maintain consistent suction and discharge performance.
