The Multiquip 30311 Stator 1 Phase 2 Pole 90 x 47 x 40L is a genuine OEM component designed for ST1 and ST1F submersible pump models. As a direct Multiquip OEM part, 30311 is manufactured to the same specification as the original, ensuring correct winding geometry, insulation grade, and dimensional fit within the motor housing. This stator is the authoritative replacement choice for operators maintaining ST1 and ST1F units and needing a verified, like-for-like swap.
Key Features
- Correct Winding Specification — Single-phase, 2-pole configuration matches the original motor winding layout exactly, preserving the electrical output characteristics your pump relies on.
- OEM Dimensional Accuracy — At 90 x 47 x 40L, this stator seats directly into the motor housing of ST1 and ST1F submersible pumps without rework or shimming.
- Confirmed Fitment for ST1 and ST1F — Sourced and verified for Multiquip ST1 and ST1F submersible pump models, eliminating guesswork when ordering a motor rebuild component.
- Restores Full Motor Output — A degraded or shorted stator causes reduced pumping capacity, overheating, and eventual motor failure; this genuine replacement brings output back to original operating levels.
- Electrical Safety Integrity — Submersible motor stators operate in wet environments under continuous load; using a genuine OEM stator with correct insulation ratings is critical to preventing electrical faults in submerged applications.
The stator is the stationary winding assembly inside an electric motor that generates the rotating magnetic field used to drive the rotor and, in turn, the pump impeller. In a submersible pump like the ST1 or ST1F, the stator must maintain consistent electrical resistance and insulation integrity while operating fully submerged. When a stator fails — typically through winding breakdown, moisture ingress, or heat damage — the motor loses torque, draws excessive current, or stops running entirely, halting water transfer until the component is replaced.
