HOW TO CHOOSE A HYDROPONIC, AQUAPONIC, ALGAPONIC, AQUARIUM, POND OR FOUNTAIN PUMP

First remember:

 • “Maximum Flow Rate” is meaningless because it is at ZERO head.

 • “Maximum Head/Lift” is meaningless because the flow at that height is only a trickle.

You need an affordable quality pump with the desired flow at your required head and lowest wattage.

Step 1: Determining Desired Flow Rate

Most ponics systems flow through a single loop allowing a single pump. A flow rate near 100 GPH is sufficient for grow beds loop up to 120 feet. If you have multiple grow-bed loops, then 100 GPH is needed for each loop. Flood/drain beds needs 2 to 4 cycles per hour.

Step 2: Calculating System Head

Measure the vertical distance from the “top” of the water in the pump tank to the pump discharge pipe. A typical requirement is 100 GPH @ 3 feet.

Step 3: Pump Selection Considerations

 • Continuous vs. intermittent pump duty cycle increases pump life, plus no need for a timer or level control.<br
 • Low cost (<$60) pumps in the 6 to 60 watt pump range are typically submersible.

 • A rule of thumb is that an average pump will last 2-4 times the stated warranty period.

 • Best to buy a backup.

Step 4: Is A Foam Filter Needed?

The objective of a filter is to keep objects/grit out of the pump.

 • While great for ponds, a foam filter in “ponics” systems is a maintenance headache as good place for algae to grow.

 • If you endeavor to have clear water… you will likely need a separate pre-filter, so a foam filter is redundant.

 • Green water algaponics systems require a vortex pre-filter; a foam filter would only clog with desirable algae.

 • Micro-algae will not hurt a pump unless it stops water flow.

Product Features

• COMPLETE SELECTION: We have 7 sizes & 13 models. Click on “PonicsFarm” near the top of the page to see them all. This model has a high quality 6 foot waterproof cord. A similar model with a 16 foot cord is available. Comes with adjustable input flow-rate screen and 3 outlet adaptors for 1/2″, 5/8″ and 3/4″ tubing.
• DURABLE QUALITY: Our Polished Aluminum Oxide Ceramic Impeller Shaft insures long pump life because it is non-corrodible and more than 3 times as hard as stainless steel. Epoxy Resin Encasement of key internal motor components prevents unwanted conductivity and corrosion of metal parts. This pump incorporates a magnetic wet-rotor design, so there is no seal to fail that would damage the pump motor.
• EFFICIENT: Neodymium Iron Boron (NdFeB) Magnets are used in all our electric motors because they are the most powerful permanent magnetic materials commercially available and increase energy efficiency. Water-Lubricated Nitrile Bushings are used because they possess a very low coefficient of friction, have inherent vibration-dampening qualities and are non-polluting.
• SAFE & EASY: Safe for fish with no exposed copper and oil free. Easy to clean with no tools required to disassemble and clean filter/impeller. Our SJTW Electric Cord is waterproof, 18# gauge copper wire, molded plug with ground, heavy duty flexible vinyl jacket, resists oil/grease/moisture, abrasion resistant and very good flexibility at all temperatures.
• SPECIFICATIONS: Salt or fresh water ready with flow Rates of 396 Gallons Per Hour (GPH) @ 0′ Lift; 370 GPH @ 1′ Lift; 363 GPH @ 2′ Lift; 343 GPH @ 3′ Lift; 306 GPH @ 4′ Lift; 264 GPH @ 5′ Lift; 221 GPH @ 6′ Lift; 132 GPH @ 7′ Lift; 3 GPH @ 8′ Lift; Max Lift – 8′ 2″. Dimensions are 3.94″ x 2.72″ x 3.39″. 120VAC – 25 WATTS – 60Hz. 1 year limited warranty when sold by PonicsFarms.
