Key Features & Benefits

1. Robust Bronze Construction

Unlike plastic pumps, the Water Puppy features a high-quality bronze body and a stainless steel shaft.⁶ This prevents the threads from stripping and ensures the pump head can withstand the high pressures of washdown applications without cracking.

2. Excellent Self-Priming

The flexible impeller design allows the pump to create a vacuum even when dry. It can lift water up to 4 feet (1.2m) vertically, meaning you can mount the pump in a dry location above the bilge or waterline for easier maintenance.

3. Debris Tolerance

The flexible vanes of the impeller can pass small solids (like sand or fish scales) that would jam a centrifugal or diaphragm pump. This makes it an ideal choice for bilge pumping in real-world conditions.

4. Versatile Ports

The pump head is designed to accommodate multiple connection types:

• Internal: 1/2″ Female NPT (standard pipe thread).

• External: 1″ Hose Barb (for large diameter bilge hose).

• Included Adapters: 3/4″ Male Garden Hose (for standard washdown hoses).

Pro-Tip for Maintenance:

“The 18660-0121 comes with a Neoprene impeller, which is perfect for water but will swell and fail if it touches oil or diesel.¹⁴ If you are using this pump for a bilge that often has engine oil in it, you should swap the impeller for a Nitrile (oil-resistant) version (Jabsco Part 6303-0003).”
