KSB Megaflow 7. Constructive Details 7.1 Casing Ample clearance volute, one piece casting including support feet. Radially split with discharge cover. Replaceable wear plate on suction side. 7.2. Nozzle Layout Axial, horizontal suction and radial vertical discharge. Optionally an intermediate suction piece with clean out and inspection manhole can be offered.
KSB Megaflow Impeller type E: Single vane closed impeller, recommended for liquids containing solids in suspension, as for example, sewage, long fibers, sludge with air concentration, fruits, vegetables, fish, sugar cane, residues in the food industry, rags, wood pieces, bones, etc.
KSB Megaflow 8.2.2. Pump with Impeller type E Fig.6 Notes: To calculate pressure PW, please consult the Type series booklet. 9. 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.
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.
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.
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.
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.

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.
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.
For pumps with Mechanical Seals it is possible to have another connections installed in the gland. In case of supply with Mechanical seals, additional instructions will follow. Accessories (Optionals) 13.1 Coupling KSB standard or from other manufacturers with or without spacer. 13.2 Electrical Motor, Turbine, Diesel Motor, etc. 13.3 KSB standard of structural welded steel with under drain channel.
KSB Megaflow 13.4 Coupling Guard KSB Standard, belts and pulley in accordance to its manufacturers. Intermediate part KSB standard. See Technical manual. Operation 14.1 First start-up procedure The following items must be provided for pump first starting: Pump and its driver must be securely fastened to the base.
KSB Megaflow 14.3 Operation supervision Depending on the disposability of personnel and on the importance of the pump, we recommend the following supervision. In case of any irregularity, the maintenance supervisor should be called immediately. 14.3.1 Weekly supervision Check: Operating point of the pump...
KSB Megaflow 15. Maintenance 15.1 Bearing Maintenance Remove vent plug. Tilt the reservoir down. Pour oil through the hole left by the vent plug until oil appears in the vertical section of the elbow connecting bearing bracket and reservoir. Fill up the reservoir Snap the reservoir back into position.
KSB Megaflow Fig.24 – Clearance Impeller type E Clearance (mm) Pump Size 80-200 0,25 + 0,05 100-250 125-315 150-400 0,45 + 0,05 200-500 Table 12 – Clearances for Impeller type E 15.4.2 Replace of the Volute Casing Wear Plate Center the impeller through the inner passage hole of the shaft (use cutter block), machining the wear region of the impeller (hub suction side) until it becomes uniform (machining limit 2 mm of diameter).
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).

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.
