Overview

The Knifel Submersible Pump 400GPH is engineered to power fountains, hydroponics, ponds, and aquariums with steady, dependable flow. Its compact form hides neatly under water, while delivering consistent performance when you need it most.

Quality you can feel and hear

Built with a high quality rotor and copper, the pump operates quietly and lasts longer than typical compact units. The result is a serene water display with minimal maintenance and a dependable daily rhythm.

AUTO-SHUT-OFF for peace of mind

When water levels drop due to evaporation or splash, the pump automatically stops to prevent overheating or burn-out. It restarts once water is restored, helping protect your setup and giving you confidence in unattended operation.

Detachable and easy to clean

The compact design makes it easy to hide and simple to disassemble without tools, so routine maintenance takes moments rather than hours.

Control the flow

A simple adjustable knob lets you dial in the exact water pressure you want. With a maximum flow of 400GPH (1500 L/H), you can tailor the display from a gentle ripple to a lively jet.

Versatile setups and real-world uses

  • Fountains and decorative water features benefit from a consistent, controllable flow.
  • Hydroponic systems require steady circulation to keep roots moist and nutrients evenly mixed.
  • Ponds and outdoor water gardens fit behind rocks or plants while remaining easy to access.
  • Aquariums demand adjustable flow to protect inhabitants while maintaining clean water movement.

Quick tips for best results

  • Fully submerge the pump before power-up and use appropriate tubing for leak-free connections.
  • Start with a low flow and gradually increase to your preferred setting.

Whether refreshing a small fountain, powering a hydroponic loop, or moving water in a compact pond, the Knifel Submersible Pump 400GPH offers dependable, adaptable performance without unnecessary fuss.
