The Jabsco Commercial Duty Water Puppy is a rugged, high-performance 12V flexible impeller pump designed for demanding commercial marine and heavy-duty onboard applications. Built for continuous operation, this pump delivers dependable water transfer performance in harsh environments where reliability and durability are essential.
Widely trusted across the marine industry, the Water Puppy series is ideal for washdown systems, livewell circulation, ballast transfer, utility pumping, and general water movement on commercial vessels and larger recreational boats.
Featuring a proven flexible impeller design, the Water Puppy provides smooth, consistent flow while maintaining excellent suction capability. This makes it well-suited for applications requiring steady output and reliable performance under frequent use.
The flexible impeller allows the pump to be self-priming, enabling installation above the waterline and reliable operation even with vertical lift. This design also contributes to quieter operation and improved efficiency compared to centrifugal pumps.
Designed for 12V DC electrical systems, this model is compatible with a wide range of commercial and recreational marine installations, making it a versatile choice for boats operating on standard 12-volt power systems.
Constructed with corrosion-resistant materials, a heavy-duty motor, and sealed components, the Jabsco Commercial Duty Water Puppy is engineered to withstand saltwater exposure, moisture, and continuous use in demanding marine conditions.
(1) Commercial Duty Water Puppy Pump: 12V DC unit with a solid bronze head.
(1) Nitrile Impeller: Pre-installed (oil-resistant for bilge/sump use).
(2) Port Adapters: 1/2" NPT to 3/4" Male Garden Hose.
(4) Vibration Dampening Feet: Pre-installed rubber grommets in the mounting base.
(1) Data Sheet: Includes wiring specifications and a full exploded-view parts diagram.
The "Commercial Duty" designation means this unit is built with a larger motor than the standard 18660-series Water Puppy. It delivers a flow rate of 9 GPM (34 LPM), providing the extra power needed for continuous-duty applications like transferring water between tanks or running a high-volume livewell.
The pump comes standard with a Nitrile impeller. Unlike standard neoprene, Nitrile is resistant to oil and diesel fuel.5 This is critical for bilge pumps, as it prevents the impeller from swelling or disintegrating if it comes into contact with fuel spills in the engine room.
The pump head is uniquely engineered to allow three different types of connections:
External: 1" (25mm) Hose Barb.
Internal: 1/2" (13mm) Female NPT.
Included Adapters: 3/4" (19mm) Male Garden Hose.

"Because the Commercial Duty Water Puppy uses a flexible impeller, it should never be run dry for more than 30 seconds. If you find the pump isn't pulling water, check the O-ring behind the end cover. Even a tiny air leak at the cover plate will prevent the pump from creating the vacuum needed to prime."
Would you like me to find the part number for the replacement Nitrile impeller kit so you can have a spare ready for your next service interval?
