The Multiquip EM18140 is a genuine OEM Impeller 5/8-18 UNF designed for the QP205SH centrifugal pump. As a factory-sourced replacement, EM18140 is manufactured to the same specifications as the original component, ensuring correct fit within the pump housing and consistent hydraulic performance. This impeller is the right call when flow rate drops, the pump loses prime, or visible wear or damage is found during service.
Key Features
- Genuine OEM Impeller Construction — Manufactured to original material and dimensional tolerances, maintaining the hydraulic efficiency the QP205SH was engineered to deliver.
- 5/8-18 UNF Thread Specification — The 5/8-18 UNF thread ensures correct installation onto the pump shaft with proper engagement and secure retention during operation.
- Direct Fitment for QP205SH — Confirmed OEM replacement for the Multiquip QP205SH centrifugal pump; installs in place of the original with no modification to the pump housing or shaft.
- Restored Flow and Pump Output — A worn or damaged impeller causes loss of flow, reduced head pressure, and potential pump cavitation; replacing with EM18140 restores rated pump performance.
- Long-Term Pump Protection — Correct impeller geometry prevents excessive wear on the pump casing and seal faces, extending the service life of surrounding pump components.
The impeller is the rotating core of a centrifugal pump — it uses centrifugal force to draw water in through the pump inlet and accelerate it outward toward the discharge port. In a dewatering pump like the QP205SH, the impeller directly determines how much water the pump can move and at what pressure. When an impeller becomes worn, corroded, or damaged, pump output drops noticeably and cavitation can develop, which causes vibration and accelerates damage to the pump housing and mechanical seal. Replacing a worn impeller promptly with the correct OEM part keeps the pump operating at its rated capacity and protects the components around it.
