Treela 12V Automatic Bilge Pump 1100GPH — Integrated Float Switch, Anti-Airlock Design

Treela's 12V automatic submersible bilge pump kit provides reliable, self-activating water removal for boats with up to 1100 GPH flow, combining pump and float switch in one compact unit.

Designed for small to medium craft, this two-piece set from Treela pairs a high-flow submersible pump with an integrated float sensor and heavy-duty motor components for continuous use in marine environments. The pumps are built to run automatically when water rises and include features intended to resist corrosion, prevent airlock and simplify routine maintenance.

How does the automatic feature activate and protect the pump?

Each Treela pump includes a built-in float switch and an electronic reed sensor that detects rising water and starts the motor without a separate external float. A relay loop design reduces the risk of high inrush current on startup and the unit is shaped to avoid airlock, improving dependable operation.

• Integrated float switch and reed sensor for hands-off activation
• Relay loop limits startup current spikes
• Anti-airlock design keeps impeller primed for reliable restarts
• Quick-release strainer simplifies debris clearing and inspection

What are the key specifications and performance details?

The pumps operate at 12 volts with a flow rating up to 1100 gallons per hour (GPH) and a max head of 5 meters, while drawing approximately 3.8 amps under typical load. Their outlet diameter and compact footprint let them fit into common bilge hose layouts without reworking plumbing.

• Rated flow: 1100 GPH; voltage: 12V; current: ~3.8A
• Maximum head: 5.0 meters (approx. 16.4 feet)
• Outlet: 29 mm (1-1/8 in) — fits standard marine hose adapters
• Physical size: 5.71 × 4.06 × 3.27 in (14.5 × 10.3 × 8.3 cm)

How durable and serviceable are these bilge pumps?

Treela constructs the pumps with corrosion-resistant materials and a water-cooled motor to extend life in salt and fresh water conditions. A stainless-steel shaft, tough thermoplastic housing and sealed motor design reduce leak risk and improve long-term reliability, while the quick-release strainer makes periodic cleaning straightforward.

• Stainless-steel shaft resists corrosion and wear
• Water-cooled motor and sealed construction for longer life
• High-impact thermoplastic housing resists cracking and UV exposure
• Removable strainer for fast maintenance and debris removal

Can I install and wire these pumps easily onboard?

Yes — the pumps are designed for straightforward installation: they are submersible, include a one-meter wire conductor, and eliminate the need for a separate float switch. Because the activation switch is built in, wiring is reduced to a simple positive/negative feed and fuse or breaker protection on the 12V circuit.

• Included 1 m wiring simplifies connection to the 12V distribution
• No separate float switch required, reducing parts and wiring
• Use a fused circuit or breaker sized to pump current for safety
• Compact footprint fits common bilge spaces and hose runs

Who is this for: The Treela 2-piece automatic bilge pump kit is aimed at recreational boat owners, day sailors, small cabin cruisers and anyone needing a compact, self-activating bilge solution. It's especially suitable if you want an easy-to-install, low-maintenance pump with decent flow capacity and corrosion-resistant construction for occasional or continuous bilge duty.
