Mantis Tornado Submersible Pump 4000

Mantis Tornado Submersible Pump 4000 The Mantis Tornado Submersible Pump 4000 is a powerful and energy-efficient DC aquarium pump designed for medium-sized marine, reef and freshwater aquarium systems. Delivering up to 4000 litres per hour with a maximum head height of 4 metres, it is ideal for sump return applications, filtration systems, media reactors and general aquarium circulation. The included controller provides 20 adjustable speed settings, allowing the flow rate to be matched to your aquarium's plumbing, overflow and filtration requirements. This makes it easy to reduce excessive turbulence, balance a sump system and operate the pump at the most efficient output for your setup. Key Features Maximum flow rate: 4000L/h Maximum head height: 4m Safe 24V DC operation Power consumption: 10W to 50W 20 adjustable speed settings Ultra-quiet and energy-efficient operation Durable high-performance ceramic bearings Compact design for sump installation Suitable for marine and freshwater aquariums Designed for continuous aquarium use Specifications Model: Tornado 4000 Voltage: DC 24V Maximum flow: 4000L/h Maximum head: 4m Minimum power consumption: 10W Maximum power consumption: 50W Controller: 20-speed variable control Inlet and outlet sizes: 25mm and 32mm Dimensions: 176.1 x 91 x 159.6mm Installation: Submersible Adjustable Flow Control The 20-speed controller allows precise adjustment of the pump output without relying only on a restrictive valve. This is particularly useful when matching the return flow to the capacity of an aquarium overflow, reducing drain noise or supplying equipment that requires a controlled water flow. Operating the pump below maximum output when full flow is not required can also reduce energy consumption, vibration and unnecessary heat transfer into the aquarium. Quiet DC Performance The Tornado 4000 uses a low-voltage 24V DC motor and durable ceramic bearing system to provide smooth, quiet operation. This makes it suitable for display aquariums installed in living rooms, offices and other areas where equipment noise needs to be kept to a minimum. Suitable Applications Sump return systems Marine and reef aquariums Freshwater aquariums Aquarium filtration systems Media reactor feed pumps UV steriliser feed applications General aquarium circulation Choosing the Correct Pump The rated maximum flow is measured under minimal head pressure. Actual water flow will decrease as vertical lift and plumbing resistance increase. Pipe diameter, pipe length, elbows, valves and connected equipment can all reduce the flow delivered to the aquarium. Before choosing the Tornado 4000, measure the vertical distance from the sump water level to the return outlet and consider the resistance created by your plumbing. The maximum rated head height is 4 metres, but the pump should not be selected to operate continuously at its absolute limit. Frequently Asked Questions What is the maximum flow rate? The Mantis Tornado 4000 has a maximum rated flow of 4000 litres per hour under minimal head pressure. What is the maximum head height? The maximum rated head height is 4 metres. Delivered flow decreases as pumping height and plumbing resistance increase. Can the flow be adjusted? Yes. The included controller provides 20 adjustable speed settings. Is it suitable for marine aquariums? Yes. The Tornado 4000 is suitable for marine, reef and freshwater aquarium systems. How much power does it use? Power consumption ranges from 10W to 50W depending on the selected speed and operating conditions. Please Note Do not operate the pump dry. Actual flow varies according to head height and plumbing resistance. Clean the pump housing, impeller and intake regularly. Confirm that the pump is suitable for your aquarium, overflow and plumbing capacity. Click to see our full range of Mantis Water Pumps
