Key Features
- Genuine OEM Retention Integrity — Manufactured to the original torque and thread specification, this nut holds the impeller firmly on the shaft under continuous pump load.
- Direct Shaft Replacement — Matches the original thread pitch and drive profile for drop-in installation on the impeller shaft with no rework or fitting required.
- Confirmed Submersible Pump Fitment — Verified for ST3020B1, ST3020BCUL, and ST3050D Multiquip submersible pumps.
- Preserves Impeller Alignment — Correct clamping keeps the impeller centered and properly seated, maintaining hydraulic efficiency and protecting the pump housing from wear caused by wobble or lateral movement.
- Corrosion-Resistant Hardware — Built to withstand continuous submersion and the abrasive slurry conditions common in dewatering and transfer pump applications.
The impeller nut is the fastener that secures the impeller to the drive shaft inside a submersible pump. It holds the impeller in precise axial position so that it spins concentrically within the pump housing, generating consistent water flow and pressure. When this nut loosens or fails, the impeller can shift or wobble on the shaft, leading to reduced pumping performance, increased vibration, accelerated wear on the pump housing and seal, and ultimately catastrophic impeller damage if left unaddressed.
