Centrifugal pumps are the most common type of pump used to move liquids through a piping system. They work by converting rotational energy from a motor to energy in a moving fluid.
Positive displacement pumps move fluid by trapping a fixed amount of it and then forcing (displacing) that trapped volume into the discharge pipe. They provide a consistent flow regardless of the pressure.
Submersible pumps are designed to be submerged in the fluid they are pumping. They prevent pump cavitation, a problem associated with a high elevation difference between the pump and the fluid surface.
Peristaltic pumps, also known as tubing pumps, move fluids through a flexible tube fitted inside a pump casing. A rotor with several rollers compresses the tube, forcing the fluid to move.
Diaphragm pumps use a combination of reciprocating action of a rubber, thermoplastic, or teflon diaphragm and suitable valves on either side of the diaphragm to pump a fluid.
Gear pumps are a type of positive displacement pump where the displacement mechanism consists of gears. These gears mesh to move fluid within the pump.
API 610 sets the standard for centrifugal pumps in the petroleum, petrochemical, and natural gas industries. These pumps are designed for high reliability and low maintenance.
API 674 sets the standards for reciprocating positive displacement pumps in the oil and gas industry. These pumps are perfect for high-pressure applications.
API 675 covers standards for controlled volume positive displacement pumps, including metering pumps. These pumps are used for precise fluid dosing and transfer, ensuring accuracy and reliability in critical applications.
API 676 defines standards for rotary positive displacement pumps, including gear, lobe, vane, and screw pumps. These pumps excel at handling viscous fluids with reliability and efficiency.
API 682 outlines guidelines for mechanical seals in pumps used in petroleum, natural gas, and chemical industries. These seals are essential for preventing leaks and ensuring safe, reliable operation.
