  Concrete Base (Pad) Information 
  Suggested Concrete Base Sizes: 

  • Duplex – Length 44” Width 25” Height 8” Spring Depth 4” Spring Type C
  • Triplex – Length 64” Width 50” Height 10” Spring Depth 8” Spring Type U
  • Quad – Length 80” Width 50” Height 12” Spring Depth 12” Spring Type CT
  • To Determine Springs = Base Length X Base Width X Depth,
  • Assume Pump System weight at ¾ of Total weight of Pad
  • Bases should never be less than 8” Thick
