Submersible pumps

ATALANTA Submersible Pumps are available with special features to handle seawater in offshore installations.

The construction is either in SS-316L or SDSS. Nickel Aluminum Bronze Impellers are also used in some applications. We specialize in tailor made solutions for specific requirements of the Customers.

General Construction of the pump and motor

Multistage centrifugal submersible pumps have radial or mixed how impellers. These are cast ensuring smooth water passages. Dynamically balanced impellers and shaft assemblies guarantee minimal vibrations and wear on the bearing bushes. All the Bearings are water lubricated and protected from sand and other suspended particles.

Discharge outlet fitted to the top bowl streamlines the flow which then passes through Non Return Valve. This can be supplied in screwed or flanged construction.

Intermediate piece (suction housing) of the pump is fitted with pre formed strainer to prevent entry of suspended particulate matter. Cable clips and guard are provided to protect Submersible cable coming out of the motor.

ATALANTA Submersible Motors are 2 pole 14 pole asynchronous wet squirrel cage induction motors that are water cooled and lubricated. The motor body is made of SDSS/316/304 and the motor ends are either in SDSS/316U304 or bronze material.

Tilting pad type thrust bearing is specially designed to withstand high values of axial thrust loads with minimum wear and tear. The stator windings are re-wirable and water cooled. The bearings are made of composites 1polymer 1rubber lined stainless steel.

The motor is provided with a reflux pressure - compensating device, to guard against pressure variations. The current is fed through special cables, brought out of the motor through' water tight' sealing glands and protected by means of a metal sheet covering the length of the pump.
