£11.82

Please sign in to see pricing

Compact 400L/hr submersible water pump with adjustable flow for circulating nutrient solution and water in hydroponic systems and reservoirs.

The Maxi-Jet New-Jet 400 is a small but capable submersible water pump designed for applications where dependable circulation is needed without taking up much room in the reservoir. With a maximum flow rate of 400 litres per hour, it is well suited to smaller hydroponic systems, nutrient tanks and water circulation duties.

Flow can be adjusted directly at the pump, allowing the output to be reduced when the full 400L/hr is not required. Its compact dimensions also make the New-Jet 400 useful in reservoirs where available space is limited.

Four suction cups provide secure positioning inside the tank, while the removable outlet allows the pump to be incorporated into a suitable pipe or hose arrangement.

Why choose the Maxi-Jet New-Jet 400?

400L/hr maximum flow – provides reliable water and nutrient solution circulation for smaller hydroponic systems.
Adjustable flow – reduce the pump output to suit the requirements of your individual setup.
Compact design – measures just 62.4 x 51.4 x 45mm, making it easy to position in smaller reservoirs.
Low 5.5W power consumption – efficient circulation from a compact submersible pump.
Four suction cups – help keep the pump securely positioned during operation.
IP68 rated – designed for submerged operation.

What is the New-Jet 400 suitable for?

The New-Jet 400 is designed for moving and circulating water, making it a useful pump for smaller hydroponic reservoirs and active irrigation systems. It can be used wherever nutrient solution needs to be moved from a tank through suitable pipework or kept circulating within a reservoir.

Its relatively small physical size makes it particularly useful where a larger pump would occupy too much reservoir space. The adjustable flow also gives growers more control when working with systems that do not need the pump's full 400L/hr output.

How to use the Maxi-Jet New-Jet 400

Position the pump in the reservoir and use the four suction cups to hold it securely in place. Connect suitable pipe or hose to the outlet where required, then make sure the pump is correctly submerged before switching it on.

Once running, use the integrated flow adjustment to increase or decrease the water output to suit the system. Avoid allowing the pump to operate without sufficient water around it.

As with any hydroponic water pump, periodically inspect the inlet and rotor area and remove accumulated debris or nutrient deposits. Keeping the pump clean helps maintain reliable water flow and reduces unnecessary strain on the motor.

Yes. The pump can be used to keep nutrient solution moving within a reservoir or as part of a suitable pumped hydroponic or irrigation setup.

Does the New-Jet 400 need regular cleaning?

Periodic cleaning is recommended, particularly when the pump is being used with nutrient solution. Keeping the inlet and rotor area free from debris and deposits helps maintain consistent water flow.

Maxi-Jet New-Jet 1200 Water Pump – 1,200L/hr

£23.73

Please sign in to see pricing

Adjustable water pump delivering up to 1,200L/hr for circulating nutrient solution through hydroponic systems and reservoirs.

The Maxi-Jet New-Jet 1200 is a versatile water circulation pump for hydroponic systems that need more flow than the smaller New-Jet models. With an adjustable output of up to 1,200 litres per hour and a maximum pumping head of 1.45 metres, it is well suited to nutrient circulation, irrigation and reservoir duties.

An integrated flow control lets you reduce the output when the full 1,200L/hr is not required, giving you greater control when matching the pump to different systems. The outlet assembly is removable, allowing the pump to be connected to suitable flexible or rigid pipework.

Four suction cups help keep the pump securely positioned, while built-in thermal protection protects the motor if operating conditions cause it to overheat.

Why choose the Maxi-Jet New-Jet 1200?

Up to 1,200L/hr flow – provides plenty of circulation for hydroponic nutrient reservoirs and irrigation systems.
Adjustable output – reduce the water flow to better suit the requirements of your growing system.
1.45m maximum head – capable of moving water vertically as well as around a recirculating system.
Thermal protection – the motor incorporates protection against overheating.
Removable outlet – allows connection to suitable flexible or rigid pipework.
Secure positioning – four suction cups help hold the pump firmly in place.

What is the New-Jet 1200 suitable for?

The New-Jet 1200 is designed for water circulation, making it a useful pump for hydroponic irrigation systems, nutrient reservoirs and recirculating setups.

Its combination of adjustable flow and a 1.45m maximum pumping head gives growers flexibility when moving nutrient solution between different parts of a system. It can also be used simply to keep solution moving within a reservoir.

Because the maximum output can be reduced, the New-Jet 1200 does not have to run at full flow in every installation. This makes it easier to tailor circulation to the requirements of the system rather than relying on a fixed pump output.

How to use the Maxi-Jet New-Jet 1200

Position the pump securely and connect suitable pipe or hose to the outlet where required. The outlet assembly can be removed or configured to suit the pipework being used within the installation.

Once the pump is operating, use the integrated flow adjustment to set the required water output. The maximum rated flow is 1,200 litres per hour, with actual delivered flow reducing as pumping height and system resistance increase.

When used submerged, make sure the pump remains covered by sufficient water or nutrient solution during operation. The pump should not be allowed to run dry.

Periodically inspect and clean the pump, particularly when it is being used with hydroponic nutrients. Removing accumulated deposits and debris from the inlet and rotor area helps maintain consistent flow and reliable operation.
