Advantages of an API610 BB2 centrifugal oil pump

• API610 BB2 centrifugal oil pumps have high energy efficiency.
• They have a wide operating temperature range hence suitable for handling fluid at different temperatures.
• They are consistent, effective and highly reliable in operation if used according to the API610 BB2 centrifugal oil pump manufacturer's instructions.
• The pumps are fully compliance with API610 standards.
• They are perfect for applications requiring high pressure.
• They are easy to maintain because the rotor is removable without dismantling the piping.
• Their double suction impeller construction reduces end thrust.
• They have a wide application versatility.
• They can pump oil over long distance.

Troubleshooting an API610 BB2 centrifugal pump

• The pump is operating in reverse. Ensure that the motor rotation direction follows the API610 BB2 centrifugal oil pump manufacturer's guide. Reverse the motor polarities.
• There is air in the Pump or suction pipework. Check that the pump and pipe network are filled with water.
• The filter or check valve is blocked with impurities. Inspect the pump filter or check valve and remove any sediment present.

• Large misalignment between the pump shaft and the motor shaft. Inspect and realign the shafts.
• Pump bearings or impeller is worn out. Check the bearing and impeller for wear and replace them if it is necessary.
• The pump operates in cavitation. Ensure the inlet valves are fully open, and the pump is working at the speed recommended by the API610 BB2 centrifugal oil pump manufacturer.

• Poor coupling alignment. Ensure the pump is properly aligned and the coupling rubber is in place.
• The pump grease is contaminated or excessive. Ensure grease is clean, and it does not exceed the pump manufacturer's specification.

• There is no priming liquid in the casing. Ensure that pump casing is filled with the liquid.
• Leakage in the mechanical seals. Replace seals.
• Leakage in foot valve or check valve. Replace the valves.

• The mechanical seals or O-ring is worn out. Replace the seals and O-ring.

Summary
API610 BB2 centrifugal oil pump is a type of pump with a between bearings design, radially split casing, double suction and complying with the standards set out in the API610 10^th edition. The API610 BB2 centrifugal oil pump's manufacturers avail them in vertical and horizontal configurations and single-stage and multistage designs. Typical construction materials for API610 BB2 centrifugal oil pumps includes carbon steel for crude oil applications and 25% Cr super duplex for seawater applications.
API610 BB2 centrifugal oil pump manufacturers produce these pumps for use in applications such as petroleum refining and distribution in offshore refineries, chemical processing, and transferring fluid under a wide range of temperatures and pressure. Pump manufacturers design these pumps for high-performance characteristics such as high capacity (up to 1740 cubic meters per hour), high maximum head (up to 280 m), and a wide temperature range (between -45 and 400 degrees centigrade). API610 BB2 centrifugal oil pumps are highly energy efficient, they are double suction, reliable, and simple to maintain and have wide application versatility.
