It is solidly built of rustproof castaluminum alloy and uses all stainless steel hardware.With minimal care, it will probably outlast yourgrandchildren. It is more efficient because it uses adiaphragm in the air chamber, preventing loss of aircharge, and eliminating the need for a snifter valveFolk rams require a minimum of 2 gpm and 3 feet of drive pipe fall to operate. The largest units canaccept up to 75 gpm, and a maximum of 50 feet of drive pipe fall. Delivery height can be up to 15 timesthe drive fall, or a maximum of 500 feet lift. The drive pipe should be galvanized Schedule 40 steel, andthe same size the entire length. Recommended drive pipe length is 24 feet for 3 feet of fall, with anadditional 3 feet length for each additional one foot of fall. Be absolutely sure you have enough water tomeet the minimum gpm requirements of the ram you choose. Rams will stop pumping and simply dumpwater if you can’t supply the minimum gpm.To estimate delivery volume, multiply fall in feet times supply in gpm, divide by delivery height in feet,then multiply by 0.61. Example: a ram with 5 gpm supply, a 20-foot drive pipe fall, and delivering to atank 50 feet higher. 20ft x 5gpm ÷ 50ft x 0.61 = 2.0gpm x 0.61 = 1.22gpm, or 1,757 gallons per daydelivery.
