WET-END FEATURES

• Floating impeller stack and face clearance design: This innovative design allows sand and abrasive particles to pass through the pump without causing blockages or excessive wear, making the NXT SB4 ideal for environments with high levels of sediment.
• Integrated thrust washer: Prevents contact between the impeller faces, minimizing friction and extending the life of the pump.
• High-quality wear-resistant composite materials: The pump is built to withstand abrasives, with 304-grade stainless steel used for the bowls, discharge head/motor adapter, and plate-type non-return valve (NRV).
• NEMA spline and stainless steel shaft: These features contribute to the overall robustness and longevity of the pump, offering added protection against corrosion and ensuring smooth operation even under heavy loads.

MOTOR FEATURES

• Asynchronous two-pole electric motor: The motor is fully constructed from stainless steel for components that come into contact with water, providing superior corrosion resistance and durability.
• Oil-filled and rewindable motor: Using food-grade white oil for lubrication ensures the pump operates smoothly and safely, even in sensitive applications.
• Heavy-duty bearings: Designed to withstand heavy loads and harsh operating conditions, these bearings extend the lifespan of the pump and reduce maintenance needs.
• Filter check valve and pressure equalizing diaphragm: These components maintain consistent pressure, reducing wear and tear and optimizing pump performance over time.
• Removable water-block lead: Allows for easy maintenance and ensures the pump remains free from water ingress that could affect performance.
• Industry-standard NEMA mounting dimensions: The NXT SB4 is designed to fit seamlessly into existing setups with standardized mounting dimensions, simplifying the replacement or installation process.
