Impeller / DiffuserThese pumps are made with SS impeller and Diffuser for high efficiency and less loss. Impellers and Diffusers are avilable with various material grades like AISI 304 / AISI 316.
ShaftStainless steel pump shafts are designed and made of AISI 304 / AISI 431 grade Stainless steel material.
Non return Valve with bodyThe integral Non return valve prevents back flow and reduces the risk of water hammer which paves the way for trouble free performance. Non return valve available with various material grades like AISI 304 / AISI 316.
Suction HousingSuction housing are designed & manufactured in investment casting with various material grades like AISI 304 / AISI 316.
Wearing Ring / Intermediate BushThe wearing Ring and Intermediate bush are made with high quality rubber like NBR which has less wear and tear resistance.
StrainerStrainers are provided in the inlet which prevent the oversized particulars entering inti the pump.
ReliabilityReliability is ensured by means of high material standard and process methods. Pump parts are made up of stainless steels. These can withstands high abrasive and corrosive environment. Bush bearing and other rubber components are also designed to withstand sand abration and erosion.
Technology - Pump
The technology of submersible pumps are multistage single suction centrifugal type and provided with integral check valve which can be coupled to a submersible electric motors. The submersible pumps are designed and manufactured to provide smooth and easy installation.
Point submersible pumps can be offered with either Point water filled submersible motors or other NEMA standard motors.
The pump is checked during each stage of the assembly process up to the final stage, where in every pump is checked for flow, pressure, power consumption and leaks.
The submersible pumps are available in stainless steel AISI 304 and AISI 316 grade in 4" and 6" submersible pumps.
|Pump shaft||AISI 304 & AISI 431|
|Diffuser casing||AISI 304 / AISI 316|
|Impeller||AISI 304 / AISI 316|
To make a positive impact in the pump efficiency level effective measures have been taken in designing every component. Superior manufacturing methods are adopted to achieve higher efficiencies.
The best material, high quality manufacturing methods and rigorous safety tests are conducted to ensure superior strength and durability of each product range.
