(once in a month) to prevent pitting of bearing surfaces. 1.5 Generally all the i-HT pumps mentioned above are similar in construction with minor changes of some parts. 1.6 Pump identification: All pumps are designated by serial number, model number, size and type.
Whenever the equipment is operated, maintained or used in any way, the procedures detailed within the Health and Safety Dossier (DHS) and any procedures detailed within these instructions shall be followed. The pump supplied by Kirloskar Brothers Limited (KBL) has been designed with safety in mind, where hazards cannot be eliminated; the risk has been minimized by the use of guards and other design features.

pressurized systems and hazardous substances. Other personal protection equipment must be worn where local rules apply. DO NOT wear loose or frayed clothing or jewellery, which could catch on the controls or becomes trapped in the equipment. Operation of the equipment for the application other than for which it is supplied can increase the risk from hazards.
Pump set must be lifted from the lifting holes provided on the pump by using suitable four chain lifting equipment. 2.6.3: Storage. 2.6.3.1: Temporary storage for up to six weeks. If the pump unit is not be used immediately it should be stored carefully in a horizontal position, in a sheltered, dry location.

b) Remove the glands, packings and lantern rings from the stuffing box if the pump is equipped in this manner. If the pump is equipped with mechanical seal, dismantle and coat the seal with light oil. c) Ensure that suction and discharge branches of the pump and all other openings are covered with cardboard, wood or masking tape to prevent foreign objects entering the pump.

d) Missing parts. e) Pump shaft rotates freely. Parts or accessories are some times wrapped individually or fastened to the equipment. If any damage or losses have been incurred; promptly notify your KBL representative, KBL Dealer and the transport company who delivered the pump. When unloading pump units, lift equally at four or more points from the base.

base plate flange, nuts and washers. The foundation should be allowed to cure for several days before the base plate is shimmed and grouted. 3.5 Base plate setting Use blocks and shims under base for support at foundation bolts and midway between bolts, to position base approximately 25 mm above the concrete foundation with studs extending through hole in the baseplate.

A flexible coupling will only compensate for small amount of misalignment and should not be used to compensate for excessive misalignment of the pump and driver shafts. Inaccurate alignment results in vibration and excessive wear on the bearings, sleeve or shaft and wear rings.

Make sure that all piping joints are air tight. Provide pipe expansions bellows when hot fluids are to be pumped. Where reducers are used, eccentric reducers are to be fitted in suction lines and straight taper reducers in discharge and vertical lines (See Fig.5). Misuse of reducers may cause the formation of air pockets in the pipe and thus preventing the correct operation of the pump.

4.1.7 Pump is primed. Never run the unit dry. The liquid in the pump serves as a lubricant for close running fits within the pump and the pump may be damaged if operated dry. The pump may be primed by using an ejector, exhauster or vacuum pump. If a foot valve is used in the suction line, the pump may be primed by venting and filling the casing with liquid.

c) With mechanical seal fitted pumps, check that there is no leakage from the stuffing box. d) Suction and discharge gauge readings. 4.4 Stopping a) Slowly close delivery valve and shut down driving unit in accordance with manufacturer’s instructions. b) Shut off external sealing liquid supply, if supplied, to relieve stuffing box pressure. c) Successful operation of the pump depends on accurate alignment.

5.4 Lubrication Details Initially bearings are lubricated during assembly. In the regreasing period these bearings should be repacked with a high quality, lithium soap base, ball and roller bearing grease free from resin and acid, not liable to harden or crumble and possessing rust preventive properties.
6. MAINTENANCE. Maintenance EHS (Environmental Hazard Safety) Instructions Following hazards may arise during maintenance work. Fluid Pressure Jet Hazards Check and ensure that the pump operates at below the maximum Working Pressure specified. Hazardous materials: Wear a suitable mask or respirator when working with chemical material handling. Hazardous Gases, Mists, Sprays and Leaks.
Isolate the equipment before any maintenance work is done. Switch off the mains supply, remove fuses, apply lockouts where applicable and affix suitable isolation warning signs to prevent inadvertent re-connection. In order to avoid the possibility of maintenance personnel inhaling dangerous fumes or vapours, it is recommended that maintenance work be carried out away from the pump location by removal of the rotating unit assembly to a suitable maintenance area.

ASSEMBLY PROCEDURE For clockwise rotation Wipe shaft [18000] with clean light oil. Screw impeller nut [33000] onto shaft at drive end as per dimension “A” given on page34. Place impeller key [32000] into key way and tap milled-down end right home under sleeve.
Page 27
Slide the heated bearing onto the shaft to about shoulder ring [19900] [coupling end]. Cool the bearing to room temperature and coat both sides with recommended grease. Coat the inside of the bearing housing [24001] with grease and slide into place over bearing.
Page 28
Check impeller for correct rotation page 31 and slide onto shaft from drive end. Screw second impeller locking nut [33000] or shaft sleeve onto shaft at drive end and using hook spanner, lock up tight against the impeller hub. From step 5 the assembly procedure is the same as for clockwise rotation pumps.
Page 29
7.5 Assembly Procedure 1. Check the “O” rings (522) for cut or flows, discard if faulty, lubricate and roll the “O” ring in groove. 2. Wipe over the shaft (180) with clean light oil. 3. Place the impeller key (320) into the keyway and interstage ring (204) along with interstage bush (313).

Check whether both Impellers are centrally placed in volute. If it did not, adjust NDE sleeve. Place the cylindrical pins (used to locate the wear ring) in their respective holes. Install casing gasket (519) with a light coat grease on both gasket surfaces.

equipment is recommended but locally approved equipment of suitable rating may be used. While lifting, the equipment adjusts the center of gravity, so that it is balanced properly. Do not place fingers or hands etc into the suction or discharge pipe outlets and do not touch the impeller, if rotated this may cause severe injury.
Page 50
Isolate the equipment before any maintenance work is done. Switch off the main supply, remove fuses, apply lockouts where applicable and affix suitable isolation warning signs to prevent inadvertent reconnection. In order to avoid the possibility of maintenance personnel inhaling dangerous fumes or vapours locations by removal of bearing housing and shaft assembly to a suitable maintenance area.
