Amount

Decoupling of pump from motor, dismantling of pump casing from base frame, extraction and removing of pump parts viz., shaft, impeller and other pump accessories. 02 no. pumps.

Mechanical transportation, loading, unloading and handling of pump using appropriate means of transport like load carrier/auto minivan upto a lead of 18 Km per trip.

Repairing of horizontal C.I. pump casing, end suction type by required mechanical operations viz., bevelling, grinding, buffing, welding etc. The welding includes DG set, welding set, skilled workers and superior quality C.I electrodes/welding rods of Make: (Essab/Adore/Advani/Drew marine) for welding of the pump casing as per requirement. Before repairing the welding portion is to be cleaned, bevelled/ V-grooved by bevelling tool/ portable grinder to billet the welding material to make the joint strong enough and leak proof to withstand full hydrostatic pressure. The welding to be carried out in fragments with Manual Metal Arc welding in multi-layer stringer beads and skip-welding. The job includes pre-heating of surface with proper heating equipment. The welding should be neat and smooth with zero porosity including removing of abrasive material. The job also includes providing and fitting of M.S. plate of required size to be fitted on the repaired portion of pump casing by required C.I. welding electrodes, if required, complete. The job also includes cutting, grinding and finishing of plate.

Installation and fitting of pump casing after repairing at site and fitting of pump parts. The job includes coupling of pump to motor and successful testing of pumping unit on full hydrostatic pressure.
