2 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 1 Life Cycle Costs In Pumps and Pumping Systems (Based On Guidelines of Hydraulic institute Standard)

3 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 2 Life Cycle Cost (LCC) The LCC of any piece of equipment is the total Lifetime cost required to Purchase, Install, Operate, Maintain, and Dispose of that equipment.

4 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach Purchase price Operating cost Maintenance cost Pumping system account for nearly 20% of worlds electrical demand and range from 20- 50% of pump energy usage in certain industrial plant operation. For majority of the facilities, lifetime energy and maintenance cost will dominate the LCC

5 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 4 Why LCC Why should organizations care about life cycle cost? Many organizations only consider the Initial purchase and installation cost of the equipment. It is in the fundamental interest of the plant designer and manager to evaluate the LCC of Different solutions before installation of new plant or major over haul. This Evaluation will help in identifying financially attractive alternative / solution. In todays competitive market organizations must continuously seek cost saving which will improve their profitability. Along with economic reasons, LCC helps in developing awareness about environmental impact of their business and conserving energy as one way to reduce emission, preserve natural resources and reduce carbon foot print. This will also help in reducing emission of Green House gases. The developed world has become acutely aware of the effect of its energy waste and the introduction of levies on CO2 emissions now directly taxes the inefficient users of energy.

7 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 6 FEATURE/ADVANTAGECUSTOMER BENEFIT Shaft CouplingsKeyed muff type couplings fitted as standard.Easily removable, unlike lower cost screwed couplings ensuring increased component life. Reduced maintenance costs. Universal Seal Chamber Customer specified mechanical seals or traditional soft packed gland arrangements. Site standards and customer specified options accommodated. Facilitates compliance with customer frame contracts for mechanical seals etc. Spacer CouplingSpacer Coupling as standard.Facilitates removal of cartridge type mechanical seals without disturbing thrust bearing assembly or driver and negates the need for expensive split mechanical seals. Substantial reduction in maintenance costs. Thrust Bearing Assembly Heavy duty thrust bearing assembly.Anti-friction or Michell type thrust bearings dependant on load. Minimum L10 life in excess of 50,000 hours under all design load conditions. HeadpieceLarge heavily engineered fabricated headpieces, ensure minimal vibration and long bearing life. Longevity of design combined with increased bearing life ensures lowest cost of ownership. CoatingsDrinking water approved coatings.Facilitates use on potable water applications.

9 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 8 LLC HSC FEATURES & BENEFITS CasingFEATURE/ADVANTAGECUSTOMER BENEFIT Axially split casing with nozzles in the bottom half casing Rotating element can be removed in- situ, without need to disturb either the pipework or driver avoiding the need for subsequent re-alignment Enhanced bearing life. Less downtime. Reduced maintenance costs. Double volute casings, where radial loads dictate. Reduces radial load and subsequent shaft deflection. Only incorporated where necessary, as double volute design tends to have an efficiency penalty. SPP (Our) policy on smaller frames is to enhance the L 3 /D 4 ratio, by incorporating more generous size pump shafts. Enhancement in L/D ratio helps in limiting shaft deflection lesser than wear ring clearance. Enhanced bearing life. Some competitors offer double volute across the range. This is not energy efficient. SPPs (Our) smaller frames will be more efficient reducing energy costs. CoatingAn efficiency enhancing drinking water approved coating is standard for water applications. This is optional for general service pumps. Reduced energy consumption/cost.

10 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 9 FEATURE/ADVANTAGECUSTOMER BENEFIT ImpellerPrecision casting in austenitic stainless steel as standard. Axially hydraulic balance of double suction design improves efficiency and enhances bearing life. Rotating assemblies are dynamically balanced minimizing vibration. Increased component life Increased cavitation resistance. Superior hydraulic performance. Increased bearing and component life. All above result in reduced maintenance costs. Impeller Fixing Positively locked and keyed to pump shaft. The new Weir Uniglide E does not incorporate a key driven impeller, hence it will be difficult to remove and may not offer the conservative thinking engineer the comfort required. Easily removable and positively driven. Pump handing can be changed insitu. Not so easy with a shrink fit impeller. Security of operation Lower maintenance costs. ShaftCorrosion resistant rigid stainless steel shaft as standard. Low L 3 /D 4 ratio ensures minimum deflection and long bearing life. Maintains optimum efficiency longer, as no contact between impeller and wear rings. Increased bearing and shaft life. Reduced maintenance and energy costs.

11 This is a proprietary document of Kirloskar Brothers Limited Life Cycle Cost Analysis – Systematic Approach 10 FEATURE/ADVANTAGECUSTOMER BENEFIT BearingsAPI type double row thrust bearing assembly. Thrust Bearing assembly situated at drive end, ensuring any thermal growth on high temperature service is not transmitted to coupling and driver. L10 life in excess of 50,000 hours, under all design load conditions. Security of operation for the more conservative thinking engineer. Wear RingsHard metallic serrated casing wear rings. Impeller wear rings are optional and can be fitted during overhaul. Long life and reduced energy consumption. Lowest whole life cost option. Minimises initial capital cost and can be fitted during overhaul if impeller wear is evident. Seal Chamber Universal seal chamber. Weir Uniglide E does not accommodate soft packed gland and is fitted with a Weir Mech. Seal. Maintains regulated pressure in at seal faces ensuring no dry running and facilitates high temperature operation. Accepts most commercially available single or double cartridge mechanical seals or traditional gland packing. Operation up to 120 o C with standard seal arrangement.
