Fully oil-free and wet-tested for optimum performance, a Little Giant 5 Series submersible pump is engineered to protect the purity of your water and the health of your plants. Weighing just under eight pounds and featuring a garden hose adapter, it’s ideal for a variety of essential growing tasks, including hand watering, general water circulation, transfer or dewatering; drawdown height for dewatering of 1/8" with screen and 1/16" without a screen. The fully submersible robust design is rated for continuous duty for reliable performance.
Ideal for feeding a water circulating system in smaller growing spaces, these premium corrosion-free stainless steel and bronze pumps provide quiet operation and zero noise pollution. Use submerged or in open air below water level to pull water from a variety of water sources or tanks. A 20' power cord provides ample length for operation.
The Little Giant F Series Wet Rotor pump lets you feed and water your grow rooms with the adjustable flow you need. Engineered for consistent water circulation, each unit is designed to pump water directly from a reservoir and can be mounted horizontally or vertically in or out of the water, depending on your need. The wet rotor design allows the pump to operate without the use of a mechanical seal or oil, for less maintenance and a healthy environment.
Tough, corrosion-resistant and dependable, the NK-2 Series is the perfect workhorse for recirculating water when fertilizers or other mild chemicals are present. The ideal size for residential applications or smaller grow rooms.
Get all the power and flow you need while using less energy and reducing your carbon footprint. Little Giant submersible magnetic drive pumps give you all the pumping benefits of a Little Giant with enhanced energy efficiency. Fully submersible and engineered for maximum corrosion resistance, these pumps are ideal for intermittent cycling/water flow in residential and commercial settings.
Enhance the sustainability of your growing operation with a Little Giant external magnetic drive pump. Engineered to work using a fraction of the electricity of traditional pump designs, these Little Giant magnetic drive external pumps are ideal for in-line applications where continual operation and water delivery are essential, such as drip or filtration systems. Available in a variety of flow rates and discharge capabilities based on your hydroponic pumping needs.
Power your irrigation system or transfer water from one grow room to another with the proven performance of an LSP Series pump. Used for decades by residential and commercial agricultural growers, the pump easily pulls water from a lake, pond, or nearby water source directly into sprinkler or drip irrigation systems. The self-priming design works consistently without hands-on maintenance – just flip the switch.
Our ABS Series automatic condensate pump is perfect for cycling water from shallow or small trays, pans, flood tables, or even larger buckets, helping to keep plants’ water supply fresh and properly aerated. This pump is ideal for propagation rooms, general irrigation needs, or water removal and is designed for constant use. It also features an integrated, unique float switch design that delivers reliable operation and is easy to access for quick adjustments.
The air inside your growing rooms and facility is just as important as the water that feeds it. A Little Giant VCMA-20 Series pump helps you handle the excessive condensate produced by HVAC systems, allowing you to recycle and reuse water for more sustainable hydroponic operations. The state-of-the-art and compact design features a vertical-type pump that fits in tight spaces, utilizing a smaller footprint.
Protect the quality of your water with a Little Giant Auto-Fill Valve Kit. It allows you to automatically maintain a constant water level in your garden by adding water slowly as the existing water evaporates. This can help reduce dramatic changes in water chemistry and temperature. The valve kit works with most Little Giant pumps, and it features a 1/2-inch NPT valve that attaches easily to your water source.
The sacrificial anode is designed to protect aluminum-bodied pumps from corrosion when the pump is exposed to other metals such as stainless steel or brass. A sacrificial anode provides the solution – extending the life of your pump and its overall performance. They are made from a metal alloy with a more “active” voltage than the metal in the pump. The difference in potential between the two metals means that the anode corrodes instead of the pump – for longer, more reliable operation.
This tank and pump combo is ideal for impractical gravity drainage areas. It removes water from sinks, dehumidifiers, air conditioners, water softeners, and more. Its portability allows for extra sinks to be placed anywhere throughout a facility, and the WRS is compact, so it fits underneath the basin.
WCR grinder package is a perfect solution for outdoor water collection and floor drain lift stations that commonly see clogged pumps from clippings and debris. Passes up to 2" solids.
Keep your facility clean and your drains flowing with a 16G Series grinder pump. The unit fits easily into floor drain pits and grinds clippings, post-harvest processing waste, and debris into organic material that runs off with your wastewater. Grinds up to 2" solids into a slurry.
Our CRO Series is made to handle commercial-size hydroponic needs, delivering 2,000 to 16,000 gallons per day of filtered water. Ideal for any large grower, its easy-to-maintain system recovers and recycles more water waste than other units in its class – giving you the ability to maximize your water usage while you minimize your water consumption. Constructed with a proven Franklin Electric pump and motor and lightweight, rust-free components.
Perfect for small grow operations, the DWRO Series’ compact size and streamlined operation handles 150 to 300 gallons per day to remove up to 98.5% of all contaminants. You can choose the level of filtration and output desired depending on your water source and growing conditions.
