NEWA Microjet Water Pumps – MC320 & MC450 Hydroponic Pumps
The NEWA Microjet Water Pumps are compact, reliable and energy-efficient submersible pumps designed for hydroponic irrigation, nutrient solution circulation and aquarium applications. Available in two models, the MC320 (320 litres per hour) and MC450 (450 litres per hour), these small but powerful pumps provide dependable water movement for a variety of growing systems.
Featuring an adjustable flow rate, removable foam filter and low power consumption, NEWA Microjet Pumps are particularly well suited to GT NFT (Nutrient Film Technique) hydroponic systems, where consistent nutrient solution circulation is essential.
Each pump comes ready to use with approximately 2 metres of power cable and a fitted UK 13A plug, making installation straightforward.

| Frequency | 50Hz | 50Hz |
| Outlet Connection | Approx. 13mm | Approx. 13mm |
Please Note: Maximum flow rates are measured under favourable conditions. Actual water delivery will reduce as pumping height, tubing length and system resistance increase.
NEWA Microjet MC320 – 320L/H
The NEWA Microjet MC320 is ideal for smaller hydroponic reservoirs and compact NFT systems. Delivering up to 320 litres of water per hour, it provides reliable nutrient solution circulation while consuming just 6 watts of electricity.
- Maximum Flow Rate: 320 litres per hour
- Maximum Pumping Height: 45cm
- Power Consumption: 6W
- Adjustable Flow Control
- Ideal for Smaller NFT Systems
NEWA Microjet MC450 – 450L/H
The NEWA Microjet MC450 provides increased water flow for hydroponic systems requiring greater circulation. With a maximum output of 450 litres per hour and a pumping height of up to 70cm, it offers additional flexibility for NFT installations and nutrient reservoir applications.
- Maximum Flow Rate: 450 litres per hour
- Maximum Pumping Height: 70cm
- Power Consumption: 6W
- Adjustable Flow Control
- Suitable for NFT Systems Requiring Higher Flow
Ideal for GT NFT Hydroponic Systems
NEWA Microjet Pumps are commonly used in GT NFT hydroponic systems, where nutrient solution must be circulated continuously or at regular intervals from the reservoir to the growing channel.
Their compact size allows them to fit inside smaller nutrient tanks, while the adjustable flow control helps growers regulate the amount of solution delivered to the system.
When installing the pump in a compatible GT NFT system, the plastic outlet connector can be removed and suitable 10mm supply tubing fitted directly into the outlet opening for a secure connection.
Adjustable Water Flow
Both NEWA Microjet models feature an adjustable flow control, allowing you to increase or reduce the amount of water being circulated.
This makes them useful for hydroponic installations where precise water delivery is important, including NFT growing channels, small irrigation systems and nutrient reservoir circulation.
Top Tip: Avoid closing the flow adjustment completely. Always ensure water can circulate freely through the pump during operation.
Low Power Consumption
Despite their compact design, NEWA Microjet Pumps provide reliable water circulation while consuming just 6 watts of electricity.
The low power requirement makes them particularly suitable for hydroponic systems where pumps may need to operate for extended periods.
Removable Foam Filter for Pump Protection
Each Microjet pump includes a removable foam filter designed to help prevent particles and debris from entering the pump mechanism.
Regular cleaning of the filter is important to maintain water flow and reduce the risk of blockages.
In hard water areas, periodic descaling is also recommended to prevent mineral deposits building up inside the pump.
Compact & Easy to Install
The small dimensions of the NEWA Microjet make it ideal for installations where reservoir space is limited.
Each pump is supplied ready to use with a fitted UK plug and approximately 2 metres of cable.
The outlet connector is suitable for approximately 13mm flexible irrigation pipe, although some tubing may require a suitable hose clip or additional sealing to achieve a secure connection.
Ideal Applications
- GT NFT hydroponic systems
- Nutrient Film Technique (NFT) growing
- Hydroponic nutrient reservoir circulation
- Small automatic watering systems
- Hydroponic propagation systems
- Small water transfer applications
- Aquarium water circulation
