Mechanical Seal If the pumped liquid is inflammable, explosive, toxic, of high cost, or when after an accurate cost analyze the result is benefic, we recommend the use of Mechanical Seal.
  • Page 14: Transportation

    Service / Storage The following procedures of service and storage are performed by KSB and by DEALER NETWORK up to effective delivery of the pump. It is the responsibility of the client to continue with this procedure after receiving the pump. When the pump is not subjected to a performance test after is sale, the areas in contact with the pumped liquid which are not painted as: stuffing box housing, wear rings, flange sealing areas, etc, receive an application of RUSTILO DW-301 by brush.
  • Page 15: Additional Procedures Of Service And Storage

    KSB Megaflow 11.1 Additional procedures of Service and Storage Pumps stored for periods exceeding one year should be serviced every 12 months. They should be disassembled, cleaned and the whole process described in the item 11 should be repeated. Pumps equipped with PACKING should have their packing removed before storage.
  • Page 16: Base Leveling

    KSB Megaflow 12.2 Base Leveling Check if the base plate is equally resting on its chock blocks. If it is OK, place and tighten uniformly the nuts on the foundation bolts. With the help of a precision level, check the leveling of the base longitudinally and transversally.
  • Page 17: Suction Pipe Line - Recommendations

    KSB Megaflow Fig. 12 – Radial Control Fig.13 – Axial Control To correct the alignment, loosen the driver bolts and replace driver over the side face or insert shim to adjust height as required. Axial and radial alignments should remain with a tolerance of 0.1 mm with the pump and driver set screws tighten securely.
  • Page 18 KSB Megaflow When the liquid being pumped has large temperature variations, expansion joints should be installed preventing the effects of contractions and expansions of the suction pipeline on the pump. With positive suction, it is advisable to install an inlet valve to close the flow to the pump when necessary. During the pump operation it should stay totally opened.
  • Page 19: Discharge Pipeline - Recommendations

    KSB Megaflow 12.6 Discharge Pipeline - recommendations To install the discharge pipeline follow these instructions: if the overpressures originated in liquid returning on long lines exceed the limits specified for the line and the pump, water hammer control devices should be installed on the discharge pipe line.

    KSB Megaflow Carefully, remove the shaft (210) from the casing pump side to drive end side. The shaft with the bearing (321) and the inner ring of the other bearing (322) will be released from the bearing bracket (330). Then, remove the parts located in the sealing chamber as packing rings (461), lantern ring (458), neck bush (456).
  • Page 28 KSB Megaflow Mount the bearing (320) and the bearing inner ring (322) in the shaft. With a piece of lead, mount the shaft in the support, from the suction side, making the external side of the bearing slide into the support until they reach the same measures in both sides of the support for setting the bearing covers.
