The Multiquip 14660000900002 is a genuine OEM Suction Cover NPT 4" designed for QP4TK, QP4TB, QP4TKT, QP4TZ, and QP4TH quick-prime trash pump models. As a direct OEM replacement sourced through Multiquip's authorized parts program, this cover is manufactured to the same standards as the original component installed at the factory. Proper fitment is confirmed across the QP4T pump series, making it a straightforward swap when your suction inlet needs servicing. Keeping this cover in good condition is essential to maintaining prime and protecting the pump's suction port from contamination and air intrusion.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional specifications as the original, ensuring correct thread engagement on the 4" NPT suction inlet.
- Direct-Fit Replacement — Threads directly onto the 4" NPT suction port with no additional adapters or modifications; designed to seat and seal as the original did.
- Broad QP4T Series Compatibility — Confirmed fitment for QP4TK, QP4TB, QP4TKT, QP4TZ, and QP4TH quick-prime trash pump models.
- Protects Pump Priming Integrity — A properly sealed suction cover prevents air leaks that can cause loss of prime, erratic flow, or pump cavitation during operation.
- Fluid-System Safety — A compromised or missing suction cover exposes the pump inlet to debris ingestion and uncontrolled discharge conditions; replacing it promptly maintains safe pumping operations.
The suction cover on a quick-prime trash pump seals the 4" NPT suction inlet when the pump is not in use or during servicing, protecting the internal pump housing and impeller from debris entry and preventing loss of the pump's self-priming capability. When the cover is cracked, missing, or has damaged threads, the pump may fail to hold prime or draw air into the volute, causing flow loss and accelerated wear on internal components. Replacing a worn or damaged suction cover with a correct OEM part restores proper inlet sealing and keeps the QP4T pump operating at its rated suction performance.
