Knifel Submersible Water Pump 660 GPH — 8.2 ft Lift, Auto Shut-Off for Fountains & Ponds

The Knifel Submersible Water Pump delivers up to 660 GPH flow with an automatic shut-off and an 8.2‑foot maximum lift for reliable pond, fountain, and water feature use.

Designed for homeowners, landscapers, and hobbyists who need a compact but powerful pump, this submersible unit balances performance with safety features. Its auto shut-off protects the motor from running dry, while the 8.2‑foot head and 660 gallons-per-hour capacity handle common outdoor water-circulation tasks. Built to be easy to install and maintain, the pump fits many small- to medium-sized setups without complicated plumbing.

How much water can the pump move and how high can it push it?

The Knifel pump is rated at 660 GPH (gallons per hour) under optimal conditions and provides an 8.2‑foot maximum vertical lift (head). Flow will vary with piping, fittings, and the height you install the outlet above the waterline.

• 660 GPH nominal flow at low head for fast circulation.
• 8.2 ft maximum head for fountains, small waterfalls, and raised planters.
• Expect reduced flow as lift and hose length increase; plan for head loss.

What does the auto shut-off feature do and why is it useful?

The built-in auto shut-off detects low water levels and stops the pump to prevent overheating or motor damage. Once water is restored to a safe level, the pump restarts automatically, reducing the need for constant monitoring.

• Prevents dry-run damage and extends motor life.
• Automatically restarts when water returns to operating level.
• Improves safety for outdoor installations prone to evaporation or splash loss.

How easy is it to install and maintain the Knifel submersible pump?

Installation is straightforward: submerge the unit, connect the discharge hose, and power on. The pump’s simple design makes periodic cleaning and debris removal quick, and routine checks of the strainer and outlet keep performance steady.

• Plug-and-play electrical connection for typical outdoor outlets (use GFCI-protected circuit).
• Accessible strainer and exterior housing for fast debris clearance.
• Compact footprint fits inside many pond skimmers, fountain basins, and containers.

What applications is this pump best suited for?

This pump is optimized for fountains, small ponds, water gardens, waterfalls, and circulating water in outdoor planters. It’s not intended for potable water supply or heavy industrial use, but it performs well in decorative and recirculation roles.

• Small- to medium-sized fountains and pond circulation.
• Waterfall returns and raised feature fills up to 8.2 ft high.
• Indoor water features where submersible operation is allowed and safe.

Who is this for: The Knifel Submersible Water Pump suits homeowners and landscapers seeking a reliable, easy-to-install pump with automatic protection against dry-run damage. Choose this model if you need a mid-range flow rate (660 GPH), a solid vertical lift (8.2 ft), and a safety-minded design that reduces maintenance and the risk of motor failure.
