Pump Shafts Manufacturers in India

A Pump Shaft is a structural element of a pump. It is linked to the prime mover and rotates with the impeller. The Pump Shafts may be carbon structural steel, alloy steel, or austenitic stainless steel. The material selected depends on the pressure and working conditions. For example, cast iron is a material used for chemical pumps. This type of material has good mechanical properties and is resistant to corrosion. However, the corrosion resistance is not as high as stainless steel. Therefore, it is not recommended for corrosive liquids.

A typical pump shaft comprises a supporting element, a protective sleeve, and guide bearings. These components are assembled to effect efficient circulation of the liquid being pumped. If the liquid is abrasive, a different material is used for the bearings. Depending on the application, they are either dry-lubricated or liquid-lubricated. Liquid lubrication is generally done with a grease fitting on the lube line. An alternative is a spring-loaded grease cup.

In a standard pump, the lubrication line connects to each bearing assembly to ensure that the bearings are lubricated. It is recommended to use a pressure equal to half of the pump discharge pressure to lubricate the bearings. There is also a valve to flush the liquid to the bearings. Usually, this is done using a solenoid valve.

The pump base should be at a suitable height and level upon installation. The pump base should be grounded to the foundation. Additionally, it should be supported vertically to reduce unwanted vibration. When the pump is installed, it is important to check the alignment of the motor and shafts to ensure proper collinearity. Besides, the shafts should be aligned to the piping system.

Another important factor to consider is the bearing sleeve. A resilient perforated bearing sleeve is adapted to receive a revolving pump shaft. This bearing is designed to prevent chattering and provide support for the shaft.

What materials are used for manufacturing pump shafts?

Pump shafts are commonly made from materials such as carbon steel, stainless steel, and various alloy steels, depending on the application's requirements for strength, corrosion resistance, & temperature resistance.

Stainless steel pump shafts are suitable for high-pressure ratings?

Yes, stainless steel pump shafts are suitable for high-pressure ratings due to their excellent strength, corrosion resistance, & durability. They can withstand the mechanical stresses and pressure encountered in high-pressure pump applications.

What is the main difference between Alloy Steel Pump Shafts & Cast Iron Pump Shafts?

Alloy steel pump shafts contain additional alloying elements, providing higher strength & toughness, while cast iron pump shafts are made of iron-carbon alloys, offering good wear resistance but lower strength compared to alloy steel.
