What are high speed pumps?

The pumping application uses a different kind of pumps. Different kind of pump system such as pumps withnon metallic wear parts, low-speed pumps, centrifugal pumps, high speed pumps etc is available. For any layman, these pumping nomenclature seems like an alien language. All they can understand from high speed pumps in India is that the pumps pass the liquid at high speed. But what exactly are these pumps? What are their benefits and why are they used? We have tried to simplify the complex pumping terms and explain what these high speed pumps are. High speed pumps in India are a revolutionary pumping application. These pumps, made from non metallic wear parts improves the pumping performance and provides mechanical advantages to that of normal pumps.  Usually, normal pumps run around 3600 rpm. Much pumping application requires speed higher than that, but because of pump reliability, maintenance, and high cost, commonly used pumps stick to the limit of 3600 rpm. High speed pumps in Ind…

Why should one use centrifugal pumps

Integrally geared centrifugal pumpsare preferred in India now-a-days. These centrifugal pumps are fairly simple. They use kinetic energy to move the liquids. The low flow pumps in India has an engine attached to the axis similar to that of ship’s water wheel.
While most of the integrally geared centrifugal pumps are used for water, some of these low flow pumps in India are also used for sewage and chemicals.  Because of the direct conversion of the energy, this is a very simple pump. As with all the pumps, there are advantages and disadvantages for these pumps too.
Advantages of Integrally geared centrifugal pumps
The biggest advantage is that they require no values or any moving parts. It also allows high flow at a very low maintenance. The output is also very steady. As there is no drive seals or values, there is no leakage in the pump. There is almost zero noise and has minimum wear. Centrifugal pumps eliminates the risk of motor damage. It can be used to pump hazardous liquids and che…
