For fixed seal versions: Lubricate the stationary part of the seal (433) with water or a soap solution and insert it in the chamber of the cover. Assemble the cover on the shroud. The standard orientation of the G 3/8 socket is in the same direction as the G 1/4 plugs in the pump casing. Make sure the cover (160) is fully adjoined to the shroud (10-6). Assemble the motor stool (341) on the cover. Assemble the hexagon cap nuts (920.03) and washers (554.01) on the tie bolts and tighten them in a crosswise fashion at the specified torque. Slide the mechanical seal kit (433.02) on the shaft. Assemble the hexagon socket head cap screws (914.03) and fasten them at the specified torque. For HP/HT cartridge seal versions: Apply a thread locker with medium strength (e.g. Loctite 2400) on the grub screws. For cartridge seal versions: fasten the grub screws (904) at the specified torque. Slide an o-ring (412.07) on the plug (903.01) and assemble it in the socket at the specified torque. See chapter 9.4 Assembling the motor and adjusting the pump shaft DPV 15 C. for assembly of the motor and adjustment of the pump shaft.

Assembling the pump DPV 15 C Heavy Duty Place the basic hydraulic assembly on the pump casing assembly. Assemble the stage casing upper (108.05). Note the location of the ribs and locate them at the level of the fill plug, so a wave spring peak is always supported by a rib. Insert o-ring (412.01) in the o-ring chamber of the motor stool (341.05). Assemble the wave spring HD (950) in the motor stool. Note the position of the wave spring in regard to the Motor Stool. Point the ends of the wave springs towards the Motor Stool. Assemble the motor stool (341.05) on the shroud. The standard orientation of the G 3/8 socket is in the same direction as the G ¼ plugs in the pump casing. Make sure the cover (160) is fully adjoined to the shroud (10-56). Assemble the hexagon cap nuts (920.03) and washer (554.01) on the tie bolts and tighten them in a crosswise fashion at the specified torque. Slide the mechanical seal kit (433.02) on the shaft. Assemble the hexagon socket head cap screws (914.03) and fasten them at the specified torque.
