Page 10: Mounting The Support Set And The Bare Shaft Kit To The Pumphead
INSTALLATION 3.2.1 Mounting the support set and the bare shaft kit to the pumphead For mounting the kit to the pumphead, the pump must not be part of a process line and must not contain lubricant. Use a hoist to place the pumphead (A) against the support set (B). - Page 11 INSTALLATION Clean the contact surfaces (B) for the bearing and the seal. Put some transmission oil on these surfaces (B). Place the retaining ring (C) in the groove (A) of the shaft. Apply an excessive amount of grease on the seal (D).
- Page 12 INSTALLATION Place the key (A) in the shaft end. Loosen the setscrew (B) from the coupling half. Screw a threaded rod (E) into the shaft end. Place the coupling half (C) on the shaft end. Install a disc (D) and nut (F) on the threaded rod (E).

Page 13: Mounting And Aligning The Drive
INSTALLATION 3.2.2 Mounting and aligning the Drive Use a hoist to lift the heavy drive. Mounting and aligning the drive must be done on the pump’s final operation position. Moving the complete pump assembly after alignment will require re- alignment at the pump’s final operation position. - Page 14 INSTALLATION Place coupling half (B) on the output shaft of the drive and slightly fasten screw (C). Make sure the shaft end has been shifted far enough into the coupling half but will not penetrate into the coupling spider (A). Use a hoist to place the drive on the support set.
- Page 15 INSTALLATION Drive a pin (A) into each drilled hole to fix the horizontal plate in the support set side plates. Use two alignment jigs (D) to check the C D C E alignment of the coupling halves in the horizontal plane. Looking from above both coupling halves (C) must touch the edge of both jigs.

Page 16: Maintenance
MAINTENANCE MAINTENANCE Cleaning Warning When cleaning the pump do not use a high-pressure spraying pistol. This might damage the seal and the bearing. Demounting the pumphead To demount the bare shaft hub the pump must be separated from the drive. This can be done in two ways: demounting the pumphead from the support set or demounting the drive from the support set. -
Page 17: Demounting The Drive
MAINTENANCE Attach a hoist to the pumphead (A). Remove the six sets of bolts and washers (B). Move the pumphead horizontally away from the support set to separate the coupling (A). Demounting the drive To demount the bare shaft hub the pump must be separated from the drive. -
Page 18: Demounting The Bare Shaft Hub
MAINTENANCE Move the drive (C) horizontally away from the support set to separate the coupling halves (A and B). Demounting the bare shaft hub Loosen screw (B) and remove the coupling half (A). Remove key (B) from the shaft end. Remove the eight sets of washers and bolts (A). -
Page 19: Disassembling The Bare Shaft Hub
MAINTENANCE Locate the two threaded holes (A) in the hub. Place two M10 bolts (B) with a threaded length of approximately 55mm. Turn the bolts (B) until they touch the face of the pumphead to which the hub is mounted. Gently turn the bolts (A) alternately half a turn clockwise to press the hub from the pumphead. -
Page 20: Assembling The Bare Shaft Hub
MAINTENANCE Use a suitable tool (B) to press the bearing (C) out of the hub (D). The seal (A) can get damaged during this step. Remove the seal (B) from the hub (A). Assembling the bare shaft hub Check the bearing and the seal before reuse. If necessary use a new bearing and a new seal. - Page 21 MAINTENANCE Use a suitable tool to press seal (B) into hub (A) until it rests on the collar. Keep the closed side of the seal upward. Apply an excessive amount of grease on the lip seal. Use a suitable tool to press bearing (B) into hub (A) until it rests on the rim.

MAINTENANCE Mounting the bare shaft hub onto the pump Clean the contact surfaces (B) for the bearing and the seal. Put some transmission oil on these surfaces (B). Place the retaining ring (C) in the groove (A) of the shaft. Apply an excessive amount of grease on the seal (D). -
Page 23: Mounting The Drive
MAINTENANCE Tighten the bolt or nuts in at least two crosswise cycles. In the last cycle tighten them with the correct torque. See section 6.3. Place the key (A) in the shaft end. Loosen the setscrew (B) from the coupling half. Screw a threaded rod (E) into the shaft end. - Page 24 MAINTENANCE Slide the drive (B) toward the pumphead. Make sure that the coupling halves (A) and the spider mesh correctly. Place the fasteners (A). Do not tighten them. Use two alignment jigs (D) to check the alignment of the coupling halves (C) in the horizontal plane.

MAINTENANCE Mounting the pumphead Attache a hoist to the pumphead. Move the pumphead horizontally towards the support set. Make sure the coupling halves (B) and the spider mesh correctly. Place the fasteners (A). Do not tighten them. Use two alignment jigs (D) to check the alignment of the coupling halves (C) in the horizontal and vertical plane. - Page 26 MAINTENANCE Tighten the fasteners (A) with the correct torque. See section 6.3. Place the coupling guard (B). Tighten the fasteners (A) with the correct torque. See section 6.3. Connect the suction and discharge lines and open any shut-off valves in these lines. Connect the drive to the electrical supply.
