American Diaphragm Pump Tanks are designed for great flexibility in installation and years of trouble-free service. They offer numerous advantages over competitive tanks. Smooth, dependable diaphragm design and operation provides precise control of system operation cycles.
Free-standing vertical tanks are available in 20 Gals, 32 Gals, 36 Gals, 52 Gals
 
  • Convenient size for cabins and summer homes
  • Ideal for continuous use applications such as lawn sprinkling
  • Tough, finish for extended life
  • Heavy gauge steel construction
  • 1 inch NPT female plumbing connection
 
Features:
  • • Metal air valve, 100 PSI working pressure.
  • • Multiple head construction provides added structural strength and more capacity within the same diameters.
  • • Interior epoxy coating is permanently bonded to the tank shell to provide the ultimate protection on the water side of the tank.
  • • Durable Butyl Diaphragm Ensures long life and prevents rubbing on the tank wall or rolling over on itself
  • • Positive Lock Retention System: Quality controlled compression in the diaphragm connection eliminates loss of air or water leaks in the tank.
  • • Ultra-UV Exterior Powder Coated: Tough powder coating provides the ultimate exterior protection and is undercoated with zinc phosphate for the highest corrosion resistance.

  • Pre-Pressurized Pump Tank Operation Cycles 
           
    Start-Up Cycle*
    Diaphragm is pressed against the bottom of the chamber.                                                                                                                                                                        		 Fill Cycle*
    Water is pumped into the reservoir, which forces the diaphragm upward into the air chamber.                                       		 Hold Cycle*
    Pump-cutoff pressure is attained. Diaphragm reaches its uppermost position. Reservoir is now filled to its rated capacity.                         		 Delivery Cycle
    Pump remains shut off while
    air pressure in top chamber forces diaphragm downward, delivering water to system.                                                                                   

    * Based on 30-50 PSI operating system.

    Sizing

    The charts below allow you to easily select the right American APT Series tank for standard-size pumps between 2-1/2 and 30 gallons in capacity and for 20-40 PSI, 30-50 PSI and 40-60 PSI pressure ranges. Minimum run times shown (from start-up) are 1 minute, 1-1/2 minutes and 2 minutes. For example, for a system that delivers 12 GPM at 30-50 PSI, with a minimum run time of 1 minute, Chart 1 indicates that the proper tank is the APT-45.
     

    If proper tank selection cannot be made using Chart 1, follow this procedure. First, find the “drawdown multiplier” by matching the pump start-up and shut-off pressures on Chart 2. For example, the multiplier for a 30-50 PSI pressure range is .31.

    Next, insert the pump GPM capacity and desired minimum run time into this formula:

    To assume dependable drawdown volumes, and in keeping with present industry practice, drawdowns are based on Boyle’s Law. For example, using a 10 GPM pump, a one-minute minimum run time, and a 30-50 PSI pressure range, the formula is as follows:

    Then, using Chart 3, select the tank that has a minimum volume that meets or exceeds your minimum volume requirement and supplies adequate drawdown at the required pressure range. Minimum drawdown equals Pump GPM X Minimum Run Time. Therefore, in the above example, select the APT-45 45-gallon tank. It provides adequate drawdown at 30-50 PSI.
