Barrel casing pump

Pumps have a hard working life, especially in the petrochemical and oil and gas industries, where some of the fluids can be very corrosive. Specifying the most suitable materials for pump casings, impellers and seals is essential for durability in service. However, changing applications can often leave pumps ill-equipped for their new task. Retrofitting new components or upgrading materials is a cost-effective method of meeting performance and reliability expectations.

The barrel casing plays a crucial role in the pump's operation and performance. Casings can be re-engineered to accept a new pump cartridge that has been created for the new application. • Pump footprint retained • No changes to surrounding infrastructure • Pump efficiency optimized

The cartridge serves several essential functions to facilitate the pump's operation and maintain its efficiency. • Containment • Pressure control • Flow direction • Energy conversion • Turbulence reduction Pump hydraulics can be improved, reliability extended and parts inventories reduced by retrofitting the cartridge.

Impellers and diffusers can be re-engineered to suit the new application. Materials and coatings can be upgraded to handle abrasive fluids. Custom hydraulics for each application ensure long life and low vibration at high energy levels. Pumps can be de-staged to meet new requirements and achieve optimum efficiency.

The shaft is a critical component that serves several essential functions in the pump's operation. It is responsible for transmitting power to the impellers as well as supporting and aligning the impellers.

The primary function of a balance drum is to improve the overall stability and efficiency of the pump. By creating a pressure differential and harnessing hydraulic forces, the balance drum ensures that the pump operates with reduced axial thrust, leading to improved efficiency, increased reliability, and extended component life.

To ensure no leakage, high-pressure mechanical seals are housed in the seal box. These are specified according to the lubrication system and type of seals required.
