Grundfos 96160144 Well Pump

The Grundfos 96160144, model 10SQ15-330, is a 3-inch submersible well pump engineered for contractors requiring high-head performance in residential and light commercial water supply applications. This 1.5 HP submersible pump operates on a 200-240V single-phase power supply and features a permanent magnet motor with a built-in variable speed drive. The technician-grade design includes soft-start technology to prevent water hammer and reduce mechanical wear, alongside integrated protection against dry-running, upthrust, and over/undervoltage. Constructed with a stainless steel housing (304 or 316 grade) and polyamide impellers, this Grundfos SQ series unit maintains a 10 GPM nominal flow rate and is rated for a maximum head of approximately 330 feet. The 1.25-inch NPT discharge and compact 3-inch diameter allow for easy installation in 4-inch or larger casings, ensuring reliable potable water pumping and pressure boosting even in demanding deep well environments.

Key Benefits for Contractors

• Integrated Protection: Features internal electronics that prevent damage from dry-running and voltage fluctuations without requiring external control boxes.
• Soft-Start Motor: Reduces amperage spikes during startup, extending the service life of the motor and protecting the plumbing system from pressure surges.
• High Efficiency: The permanent magnet motor provides high starting torque and superior efficiency compared to traditional AC motors.
• Corrosion Resistance: Stainless steel construction ensures durability in various water chemistries and prevents mineral buildup on the pump exterior.
• Compact Form Factor: The 3-inch diameter allows for installation in narrow or restricted well bores where standard 4-inch pumps cannot fit.

Common Questions

What is the maximum pumping depth for the 10SQ15-330?
The 10SQ15-330 is designed for high-head applications, supporting a maximum head of approximately 330 feet to 400 feet depending on the specific duty point, making it ideal for deep wells requiring a consistent 10 GPM flow.

Does this pump require a dedicated control box?
No, the Grundfos 96160144 features a built-in motor controller. It can be connected directly to the pressure switch and power supply without the need for an external starter or control box.

Can this pump handle sandy water?
While the SQ series features "floating" impellers that provide better sand handling than fixed designs, it is intended for clean water applications. Excessive abrasives will accelerate wear on the internal components.
