Benefits:

  • Removable rotating element is provided by back pull out design. piping need not be disturbed.
  • Interchangeability; twenty-three pump sizes utilize only six bearing journals with eight shaft sizes, fewer parts need to be kept on hand.
  • Flip-over (reversible) casings provide for clockwise or counter-clockwise rotation using "cw" or "ccw" impeller.
  • Discharge nozzle may be positioned in 45o increments.
  • Axial adjustment; easy wrench adjustment to maintaain clearance between impeller eye and suction plate.
  • Hardened stainless steel shaft sleeves are standard and protect the machined and polished machinery steel shaft.
  • Every impeller has back pump out vanes which reduce stuffing box pressure, prevents clogging or ragging and reduces axial thrust bearing loads.
  • All pumps 6315 and larger have a tapered shaft with matching tapered impeller which assures both a tighter fit and easy impeller removal.
