EG Danner® Supreme Hydroponics™ Submersible Water Pump — 200 GPH Max Flow

Oil-Free Adjustable-Flow Submersible Pump for Hydroponic Reservoirs, 200 GPH

The EG Danner® Supreme Hydroponics™ Submersible Water Pump delivers reliable, oil-free water movement for nutrient circulation, ebb-and-flow flood tables, deep water culture reservoirs, and inline water-transfer applications. With a maximum flow of 200 GPH and a maximum pumping height of 6.5ft, it handles the demands of active hydroponic systems where consistent, energy-efficient flow supports root-zone oxygenation and nutrient delivery.

The oil-free motor design removes any risk of oil contamination in a nutrient reservoir, and an adjustable flow-control dial (when submerged) lets growers fine-tune output without external valves. Included 1/4in and 1/2in tubing adaptors add connection flexibility, and the 6ft power cord reaches standard outlets in most growing environments.

Key Features & Benefits

• Oil-free motor — eliminates contamination risk in nutrient solution reservoirs, maintaining solution integrity throughout the growth cycle.
• Adjustable flow control — built-in dial adjusts output flow rate when used submerged, without external valves or pump replacement.
• Submersible or inline use — installs submerged in a reservoir or inline for water-transfer applications.
• Included tubing adapters — comes with 1/4in and 1/2in tubing adaptors for flexible connection to common hydroponic tubing sizes.
• 6ft power cord — reaches standard outlets from most reservoir positions without extension cords.

Who Should Use This

Hobby and small-to-mid-scale hydroponic growers running ebb-and-flow, DWC, NFT, or recirculating drip systems use the Supreme Hydroponics™ pump as the heart of their nutrient circulation, especially in grow tents, countertop systems, and small flood tables.

About Danner

EG Danner Manufacturing began as a small operation in a Brooklyn cellar in 1934 and has remained family-owned through its relocation to Islandia, New York in 1974. The Supreme Hydroponics™ line applies that manufacturing background to pumps built specifically for hydroponic reservoir and irrigation use.

Frequently Asked Questions

Is this pump safe to use with nutrient solutions?

Yes — the oil-free motor design and wetted components are intended for use in hydroponic nutrient solutions. Always verify chemical compatibility with highly concentrated or specialty additives before use.

Can I run this pump continuously (24/7)?

Yes — the Supreme Hydroponics™ pump is designed for continuous-duty operation in hydroponic systems. Keep the pump fully submerged when used in submersible mode to prevent overheating.

How do I adjust the flow rate?

When submerged, the built-in flow-control dial adjusts the output flow rate directly. In inline applications, flow control instead depends on an external valve or timer configuration.

Can this pump run dry momentarily without damage?

No — this pump is designed for submersible use and should remain submerged during operation. Running dry can damage internal components, so maintaining adequate reservoir water level is important.
