Struggling with water pumps that can't reach the last inch of your reservoir? The EcoPlus Convertible Bottom Draw Water Pump 585 GPH solves this with a patented bottom draw inlet that operates in less than 1/2 inch of water, eliminating waste and maximizing efficiency. For growers with smaller reservoirs, the EcoPlus Convertible Bottom Draw Water Pump 265 GPH offers the same low-profile performance at a lower flow rate.
The EcoPlus Convertible Bottom Draw Pump features a unique convertible outlet system that switches between horizontal and vertical configurations, giving you complete control over water flow direction. The interchangeable fitting design ensures compatibility across different system types, from deep water culture to nutrient film technique setups. With US Patent Pending technology, this pump represents a genuine innovation in hydroponic water management.
Built for reliability in continuous-operation environments, the 585 GPH model handles both reservoir circulation and nutrient delivery duties. To maintain optimal nutrient temperatures while circulating, this pump is an ideal companion for the EcoPlus 1/10 HP Water Chiller. The bottom draw design prevents sediment buildup and ensures consistent flow even as water levels drop during feeding cycles.

Operates in less than 1/2 inch of water depth, eliminating dry-run failures and ensuring consistent circulation even in shallow reservoirs.

Patent-pending interchangeable fitting switches between horizontal and vertical discharge, providing installation flexibility for any hydroponic application.
Delivers consistent circulation for small to medium hydroponic systems with energy-efficient operation.
Interchangeable outlet fittings accommodate standard tubing sizes for seamless integration into existing setups.
Fully submersible construction operates quietly underwater while maintaining prime during water level fluctuations.
First hydroponic pump with convertible outlet technology, offering unmatched versatility for diverse growing systems.

The bottom draw inlet is positioned at the base of the pump, allowing it to pull water from the very bottom of your reservoir. This design enables operation in less than 1/2 inch of water, ensuring you can utilize nearly all available water without the pump losing prime or running dry.
The convertible outlet uses interchangeable fittings that can be repositioned to direct water flow either horizontally or vertically. Simply detach the fitting, rotate it to your desired orientation, and reattach it securely. Refer to the included fitting guide for detailed instructions on proper installation.
The 585 GPH flow rate is ideal for small to medium hydroponic systems, typically reservoirs ranging from 20 to 100 gallons. It provides sufficient circulation for nutrient distribution and oxygenation in DWC, ebb and flow, and NFT systems. For larger commercial setups, consider the EcoPlus Convertible Bottom Draw Water Pump 730 GPH.
This model is designed as a submersible-only pump and must remain fully underwater during operation. If you require a pump for external or inline applications, we recommend the EcoPlus Eco 633 Fixed Flow Submersible/Inline Pump.
The pump includes a set of interchangeable outlet fittings designed to accommodate standard hydroponic tubing sizes. The fitting guide PDF provides detailed specifications on compatible tubing diameters and installation instructions for each fitting type included in the package.
Regular cleaning every 2-4 weeks is recommended to prevent mineral buildup. You can reduce maintenance and protect the motor by using an EcoPlus Large Pump Filter Bag to catch debris before it enters the intake. Frequency may increase if using heavily mineralized nutrient solutions.
Yes, the EcoPlus Convertible Bottom Draw Pump is designed for continuous operation in hydroponic systems. The submersible design keeps the motor cool through constant water contact, allowing for reliable 24/7 performance. Ensure the pump remains fully submerged at all times during operation.
The patented bottom draw inlet and convertible outlet system set this pump apart from conventional designs. While most pumps require several inches of water to operate effectively, this model works in less than 1/2 inch, maximizing water usage. The convertible outlet provides installation flexibility not found in fixed-outlet pumps.
