Bregton places strong emphasis on developing innovative technology that adds value for our customers.

Since its founding, Bregton has consistently invested significant time and money on research and development as a long-term strategy to support and grow our technology leadership. Short-term business cycles do not affect our commitment.

Bregton’s research and engineering facilities are working every day to develop products, services and solutions that optimize customer performance in a safe and environmentally sound manner.

To improve the efficiency of impellers and diffusers of an Electrica Submersible Pump ( ESP ), Bregron’s specialists developed and significantly improved one of the most advanced tools used in the ESP industry - the Computational Fluid Dynamics (CFD) analysis.

A detailed CFD analysis is done to predict the flow pattern inside the impeller which is an active ESP component. From the results of CFD analysis, the velocity and pressure in the outlet of the impeller is predicted. CFD analyses are done using Star CCM+ software. These outlet flow conditions are used to calculate the efficiency of the impeller. The calculated value of efficiency from the empirical relations is 55%.

The optimum inlet and outlet vane angles are calculated for the existing impeller by using the empirical relations. The CAD models of the mixed flow impeller with optimum inlet and outlet angles are modeled using CAD modelling software ProE WF3.

To find the relationship between the vane angles and the impeller performance the optimum vane angle is achieved step by step. CAD models are modeled with the vane angles between existing and optimum values.

These models are analyzed individually to find the performance of the impeller. By changing the outlet angle the efficiency of the impeller is improved to 61%.

Thus, BREGTON CFD analysis is an effective tool to calculate quickly and inexpensively the effect of design and operating parameter of pump. By properly designing pump impeller the efficiency of pump can be improved.

Besides, the software simplifies the process of optimizing and accurately predicting the future performance under different conditions with extensive case comparison capability.

Profitability of any oilfield depends on ESP runlife. Bregton's impeller and diffuser coating technologies optimize the runlife of an ESP by several advanced methods.

Bregton optimizes traditional coatings technologies and developing modern ones, such as:

1) Coating with cobalt-bound tungsten carbide, using a high velocity oxyflame (HVOF).

2) Sprayforming of Sputtering Targets ( SST ) enabling rapid fabrication of rotary sputtering targets of tin, zinc and aluminum alloys at rates exceeding 30lbs/min, providing improved density and lower gas content.

3) Plasma Electrolytic Oxidation (PEO) - depositing dense hard oxide coatings on aluminum, magnesium, titanium and nickel alloys. These coatings are harder and denser than those obtained by anodizing.

4) Electroless Nickel Plating ( ENP ) - an autocatalytic chemical reaction to form a nickel-phosphorus ( plus molybdenum, wolfram, manganese ) deposition on metal parts rather than an electric current.

5) High-chrome metallurgy ( HCM ) for housing and bar stock parts. The enhanced metallurgies have demonstrated excellent results in substantially increasing run life in severely corrosive conditions.

Using state-of the-arts technologies, improvements in the materials and coating processes, Bregton manufacture impellers and diffusers of a very wear-resistant elasticity and toughness, providing reliable working in fluids with a high abrasive content. After 5 thousand operating hours, submersible pumps with Bregton's components do not exhibit any symptoms of abrasive wear, such as increased vibrations or balance liquid quantity.
