  1. Note on Special Differential Features of Extended UP (Metric) pumps Extended UP (Metric) series covers performance range of OLD UP pumps with value added features – benefits to end customers as well as to KBL. Following features make the pumps unique of their own. ? These pumps facilitate bi-directional rotation thereby direction of rotation of the pumps can be changed without changing any components at site (except for model UP150/56). ? 400 mm delivery and above size pumps (UP400/48, UP400/51, UP400/67, UP500/51 and UP500/68) are offered with duel drive arrangement with shaft extensions at both ends. Pumps can be coupled with motor on one side and engine on the other side using a clutch arrangement. This totally avoids keeping one additional engine driven pump to take care of pumping requirement during power failure situation. o No standby pump requirement and this also ensures that the pumps are put in operation without losing any time. o The pumps are so designed that there is no need to even modify the base plates when direction of rotations are changed. o Due to this feature, direction of rotation of pump can be changed merely by changing the location of drive motor. ? These pumps are not only suitable for both gland packed and mechanical seal sealing but outline dimensions also remain same, irrespective of whether the pumps are gland packed or is fitted with mechanical seal. Hence same base plates can be used for both the versions (Except for UP250/33 pump). ? Impellers are located at the desired position without any extra efforts, with the help of special nut and sleeve arrangement. In this case worn out sleeve can be replaced without disturbing the impeller assembly. No need to deploy skilled persons for reassembly of sleeves as the impeller remains intact in its original position. Also this ensures that there is no change in hydraulic performances since impeller remains correctly in position in hydraulic passage. ? Due to modular concept, better interchangeability of components is possible, which results in to fewer inventories. ? These pumps are designed with higher shaft diameter, lower bearing span and higher bearing size compared to standard split case pumps. These features make the pumps sturdier and ensure lesser downtime and better life. ? As an option the pumps are supplied with cartridge type mechanical seals. It is easier for customer to fit the seals in the pumps without disturbing the suction Document No–Prod/diff/UP(E)/001 page 1 of 2

A major reduction in downtime and maintenance cost. ? Bearings can be replaced without removing upper half casing. This saves lot of man-hours and expenses especially for large size pumps where casings are to be removed using large cranes/ labour. ? Extended series models are with double suction impellers (except for UP150/56) giving better NPSHR and hydraulic thrust balance. ? Flanges have been standardized and are drilled as per BS4504 PN16FF making the site management much better. Document No–Prod/diff/UP(E)/001 page 2 of 2
