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

First remember:
 – “Maximum Flow Rate” is meaningless because it is at ZERO lift.
 – “Maximum Head/Lift” is meaningless because the flow at that height is only a trickle.

You need to choose an affordable quality pump that produces the “desired flow at your required lift” at the lowest wattage.

Step 1: Determining Desired Flow Rate
Hydroponic Systems – typically flow through a single loop allowing a single pump and need a flow rate near 100 GPH for each grow bed loop up to 120 feet. Flood/drain beds – need 2 to 4 cycles per hour. Fish tanks – need a least one exchange per hour or extra oxygenation. Waterfalls – need 100 GPH for each inch of width.

Step 2: Calculating System Lift
Measure the “vertical distance” from the “top” of the water in the pump tank to the pump discharge point.

Step 3: Pump Selection Considerations
 – Continuous instead of intermittent pump duty cycle greatly increases pump life, plus no need for a timer or level control.<br  – Low cost (<$60) pumps in the 3 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 pump if fish or plants depend on the pump.

Note: A foam filter is rarely needed, a screen cover is enough.

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 16 foot waterproof cord. A similar model with a 6 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.
