Johnson Pumps 09-46839-01 Accumulator Tank 1/2" Hose Barb

The Johnson Pumps 09-46839-01 is a pressurized accumulator tank designed to optimize the performance and longevity of marine and RV water systems. By incorporating this accumulator tank into your pressurized water system, you'll experience significantly longer intervals between pump cut-in and cut-out cycles when drawing small amounts of water.

Key Features:

• Reduces pump cycling frequency, extending pump service life
• Minimizes wear and tear from frequent starts and stops
• 1/2" hose barb fitting for easy installation
• Maintains consistent water pressure throughout the system
• Ideal for marine, RV, and mobile water applications
• Pressurized tank design dampens pressure fluctuations

This accumulator tank is particularly beneficial in applications where water is frequently used in small quantities—such as washing hands, rinsing dishes, or brief faucet usage—preventing the pump from constantly cycling on and off. The result is quieter operation, reduced energy consumption, and extended pump life.
