JEREPET Aquarium Water Pump, 520 GPH 20W 24V with Adjustable Flow Controller

JEREPET is a 20W, 24V DC aquarium return pump for freshwater and marine systems, with a 520 GPH maximum flow and six adjustable speed settings.

• 520 GPH maximum flow (1,968 L/h) — moves water for aquarium return and circulation needs.
• Six speed settings, adjustable from 30% to 100% — lets you set the flow for your setup.
• Maximum lift of 10 ft (3.05 m) — supports water movement across a vertical rise.
• Noise level below 30 dBA — supports quieter operation around the aquarium.
• Automatic shutoff if the pump runs dry or becomes blocked — provides a protective stop in those conditions.

For aquarium keepers and water-feature setups, choosing a pump means matching flow, lift, and installation style to the system. JEREPET is designed to serve freshwater or saltwater aquariums, including nano reef tanks, as well as fountains, hydroponic systems, and waterfalls. It can be used submerged or as an external/inline pump.

What can the JEREPET pump be used for?

JEREPET can move water in freshwater and marine aquariums, sump systems, fountains, hydroponics, and waterfalls. Its submersible or inline installation options suit different water-system layouts, including nano reef setups.

• Suitable for saltwater and freshwater use.
• Works as a submersible or external/inline pump.
• Intended for aquarium, fountain, hydroponic, and waterfall applications.

How much flow and lift does it provide, and how large is the pump?

The pump reaches a maximum flow of 520 GPH (1,968 L/h) and a maximum lift of 10 ft (3.05 m). The flow figure is measured with the largest nozzle at 0 ft (0 m) of lift, so actual flow depends on lift and nozzle selection. The pump measures 5.4 × 2.6 × 3.4 in (13.7 × 6.6 × 8.6 cm).

• Maximum flow is based on the largest nozzle at zero lift.
• Compact pump dimensions help you compare its size with your installation space.

How do the controller and protective features work?

The controller provides six speed settings that adjust flow from 30% to 100% of maximum, plus a 10-minute feeding mode and a wave-maker function. A seal impeller and ceramic shaft support operation with a noise level below 30 dBA. The pump automatically shuts off if it runs dry or becomes blocked.

• Power: 20W, DC 24V.
• Check the controller and power-supply lights if the pump does not operate; the user manual provides reference guidance.

JEREPET is suited to aquarium keepers and water-feature users who need adjustable flow, a choice of submerged or inline installation, and compatibility with freshwater or marine applications. Its six-speed controller, 10 ft maximum lift, and multiple stated use cases make it a fit for varied aquarium and water-system layouts.
