Manual and Specifications

Accumulator tanks store air and water downstream from the pump to improve the overall operation of the system. The contained air absorbs pressure fluctuations, smoothing the flow and reducing noise. Accumulators allow pumps to reach shut-off pressure smoothly and minimise on/off cycles (increasing the expected lifespan of the pump).

Features and benefits

• Compact design with easy maintenance.
• Longer pump life and reduced battery drain.
• Better control of hot water temperatures.
• Quiet operation.
• NPT threads (American National Pipe Standard Taper Pipe Thread).
