The Jabsco 50840-0012 Cyclone low-pressure centrifugal pump delivers efficient 12V DC water transfer and circulation for marine, RV, and off-grid systems. Built with a heavy-duty stainless steel motor and pump unit, it provides high flow up to 29.7 gallons per minute (110 liters/min) with pressure up to 0.6 bar (8.7 psi), while supporting quiet operation. An anti-clogging impeller, long-life mechanical seal, and 90° rotatable head enhance reliability, simplify installation, and help reduce maintenance for clean or lightly contaminated water handling.

Jabsco 50840-0012 Cyclone Stainless Steel Centrifugal Pump Unit
The Jabsco 50840-0012 is a 12V DC, low-pressure centrifugal pump designed to move water efficiently in a wide range of onboard and mobile systems. With a robust stainless steel motor and pump construction plus a high-flow performance profile, it is well-suited to circulation and transfer duties where quiet running, durability, and easy service access matter.
Application
- Water transfer for marine, RV, and off-grid systems
- General circulation tasks for clean water and lightly contaminated water
- Bilge and deck wash systems
- Ballast transfer systems
- Hot water circulation duties such as engine cooling and central heating systems
- Small-scale irrigation systems
- Cooling systems requiring quiet and efficient water movement
Installation note: This pump is non-self-priming and requires flooded suction. It should be mounted where the inlet is continually flooded and installed below the lowest fluid level to maintain flooded suction. If mounted vertically, ensure the motor is above the pump head.
Important: Do not pump gasoline, petrol, or fluids with a flash point below 37°C.
