- Designed to meet the requirements of, and are listed by the National Sanitation Foundation (NSF) under ANSI/NSF Std 61.
- The Butyl diaphragm has seamless construction and is designed to flex rather than stretch and crease like bladder tanks.
- The polypropylene liner for the water reservoir will not flake, chip, crack or peel and does not impart taste and odor to the water.
- Diaphragm, liner isolate water from contact with deep drawn steel domed shell - twice as strong as rolled steel shell of same thickness.
- A high gloss enamel finish protects tank from the elements.
- Pre-charged to 25psi: please refer to product manual for proper pre-charge setting.
Product Description
-------------------
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 a 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.
