WaterWorker 153921 44Gal Vertical Well Tank 44 Gallon

Factory pre-charge: 38 psi pounds per square inch. maximum working pressure 100 psi. Maximum operating temperature 200 F Degree Fahrenheit. engineered to provide years of trouble-free service using cold rolled steel for a higher strength to weight ratio. Rugged stable steel base with protective plastic strip. Heavy-duty butyl rubber diaphragm and durable polyolefin liner to prevent corrosion. Water worker tanks feature an appliance quality finish which is resistant to sunlight and harsh conditions. All tanks are completely lead free for safety. Meets nsf National Sanitation foundation standard 61 for clean safe drinking water. 5 year warranty. Blue tank. The WaterWorker pre-charged tanks utilize a butyl composite diaphragm which flexes up and down based on water level and air pressure as the pump fills the tank with water the air above the diaphragm is compressed increasing the pressure in the tank until the pump cut-off pressure is reached. When water is drawn from the tank the pressure inside the tank decreases until the pressure switch starts the pump. The amount of usable water for every pump cycles is called drawdown. The greater drawn-down capacity you select the less your pump cycles saving energy money and extending your pump life. Advantages over galvanized well tanks: Pre-charged tanks do not have water-logging problems like the galvanized tanks. The air and water are totally separated using a diaphragm. No external air controls needed. Pre-charged tanks have a much larger draw-down for the same physical size. Larger draw down reduces pump cycles and pump wear i.e. at 30/50 PSIG range three times the draw-down for pre-charged tanks of the same physical size. Pre-charged Tanks completely empty during each pump cycle. Pre-charged Tanks are much smaller and easier to handle that galvanized well tanks. Pre-charged tanks with a 30/50 Pressure Switch would be one-third the size of a galvanized tank with the same drawdown. Deep Well Jet Pumps could use either a vertical tank or a horizontal tank depending on space requirements and sizing. Submersible Pump applications would usually use vertical tanks again based on proper sizing. Shallow Well Jet Pumps could use vertical or horizontal tanks based on proper sizing. The rule of thumb in sizing is to count the number of fixtures in the home i.e. sinks showers toilets dishwasher faucets washing machines outside faucets etc. and multiply it by 3. Example: a house with 11 fixtures x 3 would be 33-Gallon tank. We would suggest our 44-Gallon tank which is the next larger sized tank.
