BARST's 400GPH submersible water pump is a compact, energy-efficient unit that delivers up to 400 gallons per hour with adjustable flow and a 16-foot grounded power cord for flexible indoor or outdoor water features.

Whether you need steady circulation for an aquarium, reliable flow for a small pond or fountain, or a compact pump for hydroponics and irrigation, this BARST pump combines strong performance with easy maintenance. The 25W motor provides robust water movement while remaining energy-conscious, and the detachable housing gives quick access to the impeller for cleaning. With multiple nozzle options and a long power cord, placement and flow customization are simple.

How powerful is the pump and what performance can I expect?

The BARST pump moves up to 400 gallons per hour (GPH) powered by a 25W motor and can lift water as high as 8.2 feet. Actual flow depends on head height: as lift increases, reachable GPH decreases. It performs well for medium-sized tanks, koi bowls, decorative fountains, and small pond recirculation.

• Maximum flow: 400 GPH at minimal head
• Motor power: 25 watts for energy-efficient operation
• Maximum lift: 8.2 feet for elevated features

How do I control flow and adapt it to different uses?

Flow is adjustable with a simple turn knob, letting you reduce output for gentle aquarium currents or increase it for fountain jets. The pump ships with three nozzle attachments so you can fine-tune spray patterns and pressure for specific applications.

• Easy-turn flow control for on-the-fly adjustments
• Three nozzles included for varied spray and pressure options
• Flow rate changes predictably as lift height rises

Is maintenance and installation straightforward?

The unit disassembles without tools for quick impeller access and cleaning, reducing downtime. Compact dimensions make it easy to hide in tanks or position discreetly in ponds, and the included suction cups support secure horizontal or vertical mounting.

• Tool-free detachable housing for fast cleaning
• Compact size: 3.94 x 2.72 x 3.39 inches for discreet placement
• Suction cups for stable mounting in multiple orientations

Where can I safely place this pump and what power requirements apply?

The BARST pump runs on standard household voltage (110–120V) and includes a 16-foot grounded power cord with a three-prong plug for safer installation and more flexible placement outside or inside structures. Use GFCI-protected outlets when installing near water for added safety.

• Power: 110–120V compatibility for standard outlets
• 16-foot grounded cord for flexible location options
• Suitable for indoor and outdoor water features—use GFCI for safety

Who is this for? If you run aquariums, small-to-medium decorative ponds, tabletop fountains, or need a compact pump for hydroponic or irrigation projects, the BARST 400GPH submersible pump is designed to deliver adjustable, reliable flow without occupying much space. It’s a good option for hobbyists and homeowners who want an easy-to-maintain, energy-conscious pump with versatile mounting and nozzle choices.
