  • Page 16: General Pump Assembly Sequence

    Rev 4 August 2014 A.R. Wilfley and Sons, Inc. 10.0 General Pump Assembly Sequence 10.1 Power End Assembly Step 1 – Shaft assembly. The thrust bearings (16) are two taper roller bearings mounted to the shaft in a face- to-face arrangement. The radial bearing (18) is a spherical roller bearing. The thrust bearings are a matched pair and cannot be assembled by mixing and matching pairs.
  • Page 17 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 2 – Bearing Cartridge Assembly. To install the shaft assembly from Step 1 into the bearing cartridge (99), the shaft should be vertically lowered, radial bearing or keyed side first, into the bearing cartridge. If unsure which side of the bearing cartridge is which, the side that has a lip in the bore is the thrust bearing side, and that side will be the side the shaft is lowered into.
  • Page 18 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 2 – Lowering the shaft into the bearing cartridge Press fit the bearing isolaters (47) and (49) into the bearing caps (35) and (37) respectively. Next install the o- rings (35B) into the thrust bearing cap (35), and (37A) into the radial bearing cap (37). If the bearings are grease lubricated, the area directly outboard from the bearings should be packed with grease prior to assembling the bearing caps.
  • Page 19 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 3 – Pedestal Assembly. Install the clearance adjustment bolt (149), nuts (149B), and washers (149C) into the pedestal (53). At this point it is recommended to bolt the pedestal to a rigid base or structure to prevent it from tipping forward when the wet end of the pump is assembled.
  • Page 20 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 4 – Power End Assembly. To complete the assembly of the power end, lower the bearing cartridge assembly from Step 2 onto the pedestal assembly from Step 3, making sure the threaded side of the shaft is on the bracket side.

  • Page 25 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. To prevent a packing seal failure the packing in all expeller sealed pumps must be lubricated during pump operation. An o-ring (71C) seals the case and expeller cover joint and another o-ring (83C) seals the expeller cover and the stuffing box joint as seen in the figures below.
  • Page 26 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. The flush configuration (spacer ring, lantern ring, and three rings of packing) directs the majority of the coolant towards the seal chamber, pushing solids away from the packing using more flush water.
  • Page 27 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 7 – Case Assembly (Expeller Seal). At this point, if the pump assembly is not bolted down, it must be attached to a structure or workbench before proceeding. The pump will tip forward when the case is assembled onto the pump.

    Rev 4 August 2014 A.R. Wilfley and Sons, Inc. 10.2.2 Packing Step 6-1 – Packing Seal Assembly. The packing seal creates a simple static and dynamic seal. Step 6-1 - Packing Seal Components (Weep Configuration Shown) The packing seal consists of a stuffing box (83X) four rings of packing (13), a lantern ring (29), a spacer ring (63), a gland plate (17), a gland ring (17C), two gland studs (17A) and two gland nuts (17B).
  • Page 30 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Packing Seal (Weep Configuration) The weep configuration (spacer ring, packing ring, lantern ring, and three rings of packing) directs a lesser amount of coolant towards the seal chamber than a flush configuration and uses less flush water.
  • Page 31 Rev 4 August 2014 A.R. Wilfley and Sons, Inc. Step 6-2 – Wet end assembly – Packing Seal. Install the shaft o-ring (119B) into the shaft sleeve (14) and insert the shaft sleeve onto the shaft (6) butting it up against the release collar (36). Take the stuffing box assembly (83P) and slide it onto the shaft sleeve (14).
