The T-H Marine HYDRA™ Livewell Pump (PMP-LWL8-DP) is a professional-grade 800 GPH livewell circulation pump engineered for serious anglers who demand consistent performance and easy serviceability. Backed by 4,000 hours of rigorous testing, this 12V pump is built to deliver reliable livewell water circulation in demanding marine environments.
A standout feature is the anti-airlock design, which ensures dependable restarts even when air is trapped in the line — a common issue that sidelines lesser pumps. The precision-balanced motor paired with a 316 stainless steel motor shaft minimizes vibration and noise while resisting corrosion over the long haul.
Servicing the HYDRA is faster and easier than traditional pumps thanks to the dual-lock cartridge system, which allows full motor removal without disconnecting any hoses or plumbing. The removable long nozzle adds further convenience for quick maintenance access. Stator vane technology optimizes flow efficiency, ensuring you get the full 800 GPH output your livewell needs.
This pump also doubles as a wash-down source via its dedicated secondary outlet, and includes an integrated sealant channel to prevent leaks at the installation point. Both short and long threaded intake options are supported for flexible installation configurations.
