Shurflo Livewell - Aerator Pumps

Shurflo Livewell & Aerator Pumps: Built for Serious Anglers

When bait survival is on the line, the pump powering your livewell or baitwell can make or break a day on the water. Shurflo, a trusted name in marine fluid management and now part of Pentair, has engineered a focused lineup of livewell aerator pumps purpose-built for the demands of sport fishing — from bass tournaments to offshore trips. With multiple product series addressing different tank sizes and installation needs, Shurflo covers nearly every livewell scenario an angler might face.

The Piranha Series: Reliable Submersible Aeration

The Piranha is Shurflo's flagship aerator pump line, available in both straight-port and angled-port configurations to suit different livewell layouts. The tough, high-density nylon housing and heavy-duty water-cooled motor give Shurflo Livewell Pumps unparalleled reliability in the corrosive marine environment. Flow rates span from 600 GPH up to 1,100 GPH, giving anglers the flexibility to match pump output to their tank volume.

One of the Piranha's most critical engineering features is its patented anti-airlock feature, which allows the pump to clear trapped air in rough water or when the boat is anchored — a common failure point for lesser pumps that can leave bait gasping at the worst possible moment. All Piranha Series aerator pumps also have a removable cartridge for easy cleaning , and the dual port fitting allows for easy washdown pump connections , adding utility beyond pure livewell duty. The pumps ship with a tinned 6-foot wire assembly, include a hex nut and washer, and are ignition protected to meet ISO 8846 standards — an important safety certification for enclosed engine compartments.

The Bait Sentry Series: Magnetic Drive Innovation

For anglers seeking an even more robust solution, Shurflo's Bait Sentry series takes a different engineering approach. The sportfishing livewell application requires an extremely rugged pump to withstand the harsh marine environment, and the Bait Sentry is designed for easy installation and trouble-free operation — with magnetic drive technology that eliminates unnecessary failures. Because the impeller is magnetically coupled rather than directly driven, debris that enters the pump cannot damage the motor, extending service life considerably. Available in 500 GPH and 800 GPH variants, dual ports allow for easy washdown pump connections on these models as well.

Pro Baitmaster II: Heavy-Duty Diaphragm Performance

Shurflo rounds out its livewell pump lineup with the Pro Baitmaster II, a heavy-duty solution for larger tanks and dual-duty livewell/washdown use. This model features a 4-chamber diaphragm design for consistent, reliable flow, a continuous-duty corrosion-resistant motor with thermal overload protection, and is self-priming — capable of running dry without damage. It is UL Marine listed and ignition protected, making it one of the most versatile pumps in the Shurflo marine catalog.
