How Centrifugal and Positive Displacement Pumps Work (The Core Difference) A centrifugal pump accelerates liquid through a rotating impeller. Kinetic energy converts to pressure e

What Is Upstream Pumping (USP) Seal Technology? Upstream pumping borrows a proven concept from gas-lubricated seals and applies it to liquid environments. The inboard seal face ca

What Is a Reciprocating Positive Displacement Pump? 15,000 psi of fluid pressure does not happen by chance. It is the product of a machine that captures a fixed volume of liquid a

On August 28, CNOOC released its semi-annual report for 2024, showing that the company achieved 185.11 billion yuan of oil and gas sales revenue during the reporting period (the same below), an increase of 22% year-on-year; The net profit returned to the mother was 79.731 billion yuan, an increase o

The Organization of the Petroleum Exporting Countries (OPEC) cut its forecast for oil demand growth in its latest monthly oil market report, raising concerns in the market. At the same time, the outside world is also continuing to pay attention to the tensions in the Middle East, and the future vola

How Centrifugal and Positive Displacement Pumps Work (The Core Difference) A centrifugal pump accelerates liquid through a rotating impeller. Kinetic energy converts to pressure energy inside the volute. Flow is not constant — it varies dramatically with discharge head. When a valve downstream cl

What Is Upstream Pumping (USP) Seal Technology? Upstream pumping borrows a proven concept from gas-lubricated seals and applies it to liquid environments. The inboard seal face carries a precision‑etched spiral groove pattern. When the shaft rotates, those grooves draw clean barrier fluid toward

What Is a Reciprocating Positive Displacement Pump? 15,000 psi of fluid pressure does not happen by chance. It is the product of a machine that captures a fixed volume of liquid and pushes it forward with every stroke. That machine is a reciprocating positive displacement pump. Unlike a centrifugal
