The Multiquip 1878000040 Open Impeller 2 is a genuine OEM component designed for QPT305SLT, QP305SLT, QPT205SLT, and QP205SLT centrifugal pump models. As a direct Multiquip OEM part, 1878000040 is manufactured to the exact specifications required to maintain proper pump output and hydraulic efficiency. This impeller is a precision fit within the pump volute, ensuring correct clearance and flow characteristics that an off-spec part cannot replicate. If your pump is showing reduced pressure, loss of prime, or irregular flow, replacing the impeller with this genuine OEM component restores the pump to its original operating condition.
Key Features
- Genuine OEM Impeller Geometry — Blade profile and vane angle match original design specifications, preserving rated flow and pressure output across all operating speeds.
- Direct-Swap Installation — Engineered to mount directly onto the pump shaft with correct bore and keyway dimensions, requiring no rework or shimming during installation.
- Confirmed Fitment — Verified for use with QPT305SLT, QP305SLT, QPT205SLT, and QP205SLT centrifugal pump models.
- Restored Pump Efficiency — A worn or damaged impeller causes cavitation, flow loss, and motor overload; replacing it with part 1878000040 returns the pump to full hydraulic performance.
- Open Impeller Design — The open-vane configuration allows handling of lightly entrained solids without clogging, suited to the dewatering and transfer applications these pump models are built for.
The impeller is the rotating core of a centrifugal pump — it converts shaft rotation into fluid velocity and pressure by accelerating water outward through its vanes and into the pump volute. An open impeller, like the Multiquip 1878000040, uses exposed vanes without a front shroud, which reduces the risk of debris binding and makes the component easier to clean and inspect in the field. When the impeller wears, chips, or becomes imbalanced, the pump loses prime more easily, output pressure drops, and the drive shaft and seal assembly experience increased stress — making timely replacement essential to protecting the broader pump assembly.
