Dismantle upper wear ring support. Loosen bolts for impeller hub two turns. Knock carefully on (or press down) all bolts. When impeller is loose remove all bolts. Remove bolts between volute casing and cargo leg. Replace one bolt between volute casing and pump unit diagonal on each side of the pump with lifting bolts(M12x100). Remove remaining bolts between volute casing and pump unit. Lower volute casing, suction cover, impeller and wear ring in one piece.

Fig. 03 Slide/lift volute casing together with impeller and suction cover out of well (fig.04). To avoid damage on suction well coating, volute casing must be placed upon slide. W ear rings can now be replaced. Suction cover and impeller can now be dismantled from the volute casing.

Assembling sequence CHECK ALL SEAL ELEMENTS, BACK-UP RINGS, SEAL ELEMENT GROOVES, AND SEAL FACES. PAY SPECIAL ATTENTION TO THE TEFLON RINGS AND BE ABSOLUTE SURE OF NO DEFORMATION NOR RADIAL GROOVES. NEVER INSTALL DAMAGED O-RINGS. CHECK SEAL FACES ON PUMP AND BE SURE OF NO CORROSION, CRACKS, DIRT ETC. ---- USE ONLY GENUINE SPARE PARTS --- ALL SCREWS AND NUTS HAVE TO BE ASSEMBLED WITH SPECIFIED TORQUE. IF NO TORQUE IS SPECIFIED, USE TORQUE ACCORDING TO FOLLOWING TABLE:  ACID RESISTANT BOLTS AND NUTS, QUALITY A4-80 M6 9.2 Nm

 All bolts and nuts are to be fastened using a torque wrench, and acid resistant bolts are to be coated with "Molybdenum disculphide" (Molycote) on threads and under bolt heads / nuts prior to assembling.

 All assembling has to be done in reversed way according to the dismantling sequence. PAY SPECIAL ATTENTION TO THE FOLLOWING POINTS: Hydraulic motor If a new hydaulic motor is installed, check that both drain connections are plugged with Check that the shaft seal is removed.

Back Stop Unit Check direction of back stop unit. (Counter clockwise, seen from threaded end of the shaft.) Ball bearing Ball mounting slot pointing downwards against the back stop unit when mounting ball bearing. Mechanical Oil Seal  Assemble mechanical seal according to instruction 290-36-4E. Clean seal faces with clean rags wetted with denaturated alcohol. Lip seal arrangement Use assembling cylinder to assemble ceramic sleeve. Do not remove the cylinder before all FRAMO shaft seals has been installed. When assembling lip seals be sure that support ring is tightened up until metallic contact. This to avoid screws to loosen. The spring marked with red colour on the double lip seal shall be mounted against mechanical seal. THE CERAMIC SLEEVE MUST BE HANDLED VERY CAREFULLY AS IT IS VERY BRITTLE AND MAY CRACK IF DROPPED Impeller Hub When assembling impeller hub, be careful not to damage o-rings. Be sure to lock the impeller hub bolt properly. Check the shaft alignment according to fig. 19. The retainer ring has to be fitted in the right position at the end of the ceramic sleeve, by using some grease.

Fig. 19 Wear Rings When mounting new wear rings be sure that support ring is tighten until metallic contact.

Volute casing with impeller Slide volute casing and impeller into suction well. Framo seal element is to be placed on top of impeller when volute casing is in position below impeller hub. Check position of the guiding pin in flange connection between pump unit and volute casing. Lift the complete unit with 2 lifting bolts M12x100 until these bolts can be replaced with the original bolts. Assemble the bolts for impeller hub and volute casing. Tighten all bolts evenly. To avoid rotation of impeller hub use anti rotating tool (special tool list).

Pressure test of pump

The cofferdam must be pressure tested by blinding off the exhaust trap vent pipe. Unscrew the complete relief valve and connect a manometer to the G1/4 connection. Connect air/nitrogen supply to the snap-on coupling on the purging connection and increase pressure to max. 3 bar. Flush all parts, connections, seals etc., which have been dismantled, with soapy water to be sure of no static leakage. Remember to remove blind plug from exhaust trap vent connection and assemble the pipe afterwards. Install the complete relief valve.
