Our F-series triplex mud pumps are designed and manufactured based on the American Emsco F-series mud pump strictly in accordance with API 7K specification. All of the expendable parts are interchangeable with any other similar spare parts produced according to API specification. Therefore, repair and maintenance of our product are possible all around the world.
Features
-
Our triplex mud pump features a compact and robust design, offering a small footprint without compromising on power. Engineered for high performance, it meets the demanding technical requirements of high pumping pressure and large displacement in modern drilling operations.
-
The pump is designed with an extended stroke length and operates at a lower stroke rate. This combination significantly improves the pump's fluid intake efficiency and greatly extends the service life of fluid-end expendable parts. The incorporation of an advanced suction pulsation dampener further ensures optimal suction performance under varying operating conditions.
-
At the power end, a dual lubrication system combining forced and splash methods is employed. This reliable lubrication architecture effectively enhances durability and prolongs the service life of the power end components.
