Frequently Asked Questions
What is the difference between the Newa Jet NJ1700, NJ2300, NJ3000, NJ4500 and NJ6000?
The difference is flow rate and physical size. The Newa Jet range runs from the NJ1700 at 1000 to 1700 L/H right up to the NJ6000 at 6000 L/H, with max head height, power draw and outlet size all stepping up to match, as shown in the spec table above.
Can a Newa Jet pump run fully submerged in my reservoir?
Yes, every Newa Jet pump is designed to run fully submerged in a tank or reservoir, and can also be mounted outside the tank if you prefer, using the inlet adapter fitted as standard.
Will a Newa Jet pump work with my IWS FlexiTank?
Yes. Any Newa Jet pump will work with an IWS FlexiTank, and the Newa Jet NJ3000 IWS Pro Fill version comes fitted with a 2-pin plug that connects straight to the IWS brain unit so it powers up automatically when the feed timer activates.
What pipe size do I need for a Newa Jet pump?
The NJ1700, NJ2300 and NJ3000 take 21.4 to 26.9mm pipe, and the NJ4500 and NJ6000 take 25 to 35mm pipe. Our 25mm Pro Flexi Pipe fits all of them.
Is the Newa Jet NJ3000 IWS Pro Fill the same pump as the standard NJ3000?
Yes, it's the same NJ3000 pump and the same flow rate, just fitted with the 2-pin plug for a direct connection to an IWS brain unit instead of a standard mains plug.
Description
The Newa Jet Submersible Pump range is a line of high flow, low noise water pumps for hydroponic reservoirs, feed tanks and irrigation setups. They are built for growers who want a pump that just gets on with it: strong flow, barely any noise, and nothing to fiddle with once it is in. There is a size for most jobs, from the 1700 L/H Newa Jet NJ1700 for a single reservoir right up to the 6000 L/H Newa Jet NJ6000 for bigger irrigation and dosing runs.
Efficient. Silent. Bulletproof. Every Newa Jet pump moves serious volumes of water or nutrient solution while staying whisper quiet and close to maintenance free. Whether you are feeding multiple pots, circulating a reservoir, or running a full irrigation system, they hold consistent pressure without heat buildup or vibration noise. Once it is plumbed in, it just works.
Adjustable flow control on the inlet gives you full command over how much liquid moves through the system. Dial it down for gentle feeding or open it up as your grow area expands. Water, nutrients, or mixed solutions all run through it without fuss.
Every Newa Jet pump can be used fully submerged or mounted outside the tank. An inlet adapter is fitted as standard for direct pipe connection, so they drop straight into tanks, reservoirs or custom plumbing.
The protected motor design stops the pump overheating on long runs, and the rotary inlet regulator lets you fine-tune flow without putting the motor under strain, so long feed cycles and demanding hydro systems are no problem.
Specialist IWS compatibility: the Newa Jet NJ3000 IWS Pro Fill comes fitted with a 2-pin plug that connects straight to the IWS brain unit, so power is supplied automatically the moment the feed timer fires.
Pair any Newa Jet pump with 25mm Pro Flexi Pipe for smooth flow and an easy install, or go straight for the IWS Dripper Pump & Pipework Kit, which is built around the NJ6000 and gives you all the fittings to plumb a Newa Jet pump into an IWS FlexiTank or IVXX tank properly, rather than the pipe flopping out of the top.
In the box: one Newa Jet pump with its power lead and the inlet adapter already fitted. No extra hose, pipe or fittings are included, so check the pipe and pump kits linked above if you need the plumbing to go with it.

- High flow rates with low energy consumption
- Extremely quiet operation for indoor grow spaces
