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.
DO NOT USE WITH SOLAR POWER! Voltage often fluctuates below requirements.
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 793 Gallons Per Hour (GPH) @ 0′ Lift; 775 GPH @ 1′ Lift; 761 GPH @ 2′ Lift; 726 GPH @ 3′ Lift; 687 GPH @ 4′ Lift; 660 GPH @ 5′ Lift; 608 GPH @ 6′ Lift; 528 GPH @ 7′ Lift; 449 GPH @ 8′ Lift; 330 GPH @ 9′ Lift; 211 GPH @ 10′ Lift; 79 GPH @ 11′ Lift; Max Lift – 11′ 6″. Dimensions are 4.84″ x 2.72″ x 3.82″. 120VAC – 60 WATTS – 60Hz. 1 year limited warranty when sold by PonicsFarms.
Great pump I bought this pump 3/31/13. I’ve been running this non-stop for almost a year now in my aquaponics system without fail. This pump is an animal. I really didn’t need one this powerful but I’m into over kill. I really had to dial it back or it would flood the grow bed along with the floor. I’m going to buy another one for back up but less GPH. UPDATE: March 31, 2014. The pump started making some really scary noises the last few days and died completely today. In all fairness to the pump, I…
Fine little pump, GREAT customer service. 0
