  1. Frame - Heavy duty cast iron with precision bore provides rigid support for rotating assembly.
  2. Shaft - Large diameter shaft supported by two widely spaced ball bearings provides smooth quiet operation.
  3. Shaft Adjusting Nut - Permits axial adjustment of impeller - for regulation of capacity and head and to compensate for wear without dismantling pump.
  4. Stuffing Box - Furnished as standard with packing,  lantern ring,  and  split gland for easy servicing. Special stuffing boxes or mechanical seals are available.
  5. Liquid End - Four-piece assembly with separate suction head permits easy access to impeller, low cost maintenance. Standard cast iron construction designed for working pressure of 150psi. Can be manufactured of other materials to meet special applications without changing power end.
  6. Impeller - Semi-open adjustable impeller with extra heavy vanes gives outstanding performance and wear resistance. Impeller keyed to shaft with precision taper fit to assure easy impeller removal and perfect alignment
  7. Suction Head - Separately removable, permits inspection and servicing without disturbing discharge piping or pump alignment.
  8. Bearings - Two widely spaced ball bearings provide solid shaft support. In given Fig., frame has a double row bearing at the stuffing box end. Fig. 4021H  frame  has  larger shaft with double row bearings at both ends.
  9. Interchangeability:-
    Figs. 4011, 4021 and 4021H power frames are each suitable for several sizes of liquid ends. In addition, Figs. 4011, 4021 and 4021H liquid ends thru 3" are interchangeable. This permits 4011 liquid ends to be assembled on 4021 power frames thus providing a much heavier pump for heavy duty service. Selection tables indicate the most suitable combinations for various pumping conditions.
