Pentair - Pentair Purex Screw Set Self-Lock A-113 - 71708
- Self-Locking Security: Engineered to resist vibration and rotational torque, ensuring the impeller stays firmly attached to the shaft.
- Corrosion-Resistant Material: Manufactured from high-grade stainless steel to withstand constant exposure to chlorinated or salt-water environments.
- Direct A-113 Compatibility: Specifically threaded and sized for the Pentair/Purex A-113 series, providing a factory-perfect fit.
- Prevents Motor Damage: A secure impeller prevents "shaft play" and vibration, which can lead to premature motor bearing failure.
The Pentair Purex Self-Locking Impeller Screw Set (71708) is a critical hardware component designed specifically for the Purex A-113 Series pool pump impeller. This specialized set includes the reverse-thread screw and the required washer/lock mechanism to secure the impeller to the motor shaft.
Because the A-113 impeller rotates at high speeds, a standard screw can loosen over time; the 71708 set features a self-locking design to prevent the impeller from spinning off during pump operation. Replacing these components during an impeller swap or motor change is essential for maintaining the mechanical integrity of your pump's "wet end."
