Specifically designed to be installed downstream of your pump, these tanks help reduce unwanted cycling, pulsation and pressure spikes, while helping to prolong pump life and save battery power. SHURFLO accumulator tanks use a patented domed displacement diaphragm to minimize noise and power usage. These accumulators are available in both a 24 Ounce nylon tank as well as a 2 Gallon stainless steel tank, helping to accommodate any space constraints in your RV.
