1500 GPH Electric Bilge Pump

Dependable Rule Bilge Pumps for Marine Environments

When water intrusion threatens your bilge, you need a pump you can trust without hesitation — and Rule has been the name boatbuilders and boaters rely on for decades. The Rule 1500 GPH Electric Bilge Pump is a submersible, non-automatic workhorse engineered to move serious volumes of water quickly when conditions get rough, whether you're dealing with rain, spray, a leaking fitting, or a genuine emergency.

At the heart of every Rule 1500 is a fully submersible motor built around a non-corroding stainless steel shaft, sealed against water intrusion and cooled by the very water it pumps. The vibration-free centrifugal impeller runs silently and can withstand short-term dry running without burning out the motor — a critical safety margin when bilge levels fluctuate. Anti-airlock protection keeps the pump priming and moving water even when air pockets would stall a lesser design, and moisture-tight seals throughout the housing protect the internal components from the harsh, damp marine environment the pump lives in.

Compact and energy-efficient, the long-life motor is built for tight bilge spaces and supports both horizontal and vertical mounting, giving you flexibility across a wide range of hull and bilge configurations. Used by leading boatbuilders worldwide, the Rule 1500 platform has earned its reputation as one of the most trusted names in marine dewatering.

Key Features:

• High Performance: 1500 GPH open-flow rate, with more pumping capacity and design refinement than comparable competitive pumps.
• Durable Design: Non-corroding stainless steel shaft, marine-grade blocked/sealed wiring with 6' leads, moisture-tight seals, and full rust and corrosion protection throughout.
• Anti-Airlock Protection: Maintains consistent flow and priming even when air pockets are present in the line.
• Ease of Maintenance: Snap-lock strainer base unsnaps in seconds for fast, tool-free debris removal.
• Flexible Installation: Mounts horizontally or vertically to fit tight or unconventional bilge spaces.
• Flexible Operation: Non-automatic design requires a float switch or water-sensing switch for activation; can also be wired to a bilge pump panel switch for remote/manual operation from the helm.
• Quiet Operation: Silent, vibrationless performance minimizes noise and onboard fatigue during extended runs.
• Run-Dry Protection: Short-term dry running capability prevents motor burnout if the bilge empties before the switch cycles off.

Capacity (Open Flow — Varies with Lift/"Head"):

• @ 0m (0'): 1500 GPH
• @ 1m (3.35'): 1200 GPH
• @ 2m (6.7'): 680 GPH

Note: All centrifugal bilge pump capacities are rated at open flow, with no hose or resistance impeding output. Actual performance decreases with lift height, hose length, elbows, and internal hose corrugation — if your installation has demanding lift or run requirements, consider sizing up to a higher-capacity Rule pump.

Additional Information:
The Rule 1500's outlet port is compatible with 1 1/8" ID hose — shop our full range of bilge pump hose and stainless clamps for a secure, leak-free install. Pair with a Rule float switch or panel switch (each sold separately) to complete your bilge pump system. Backed by Rule's 3-year limited warranty, this pump remains one of the most trusted choices for reliable, efficient water removal aboard boats of all sizes.
