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 has a firm and compact structure, and is small in size. With outstanding performance, it is adaptive to the technical requirements of high pumping pressure and high displacement in well drilling.
Our drilling pump has a longer stroke and can operate with a lower stroke rate. This effectively improves water feeding performance of the pump and greatly lengthens the service life of expendable parts in the fluid end. With advanced structure, the suction pulsation dampener is helpful to make the pump realize its best suction performance.
The power end of this slurry pump adapts a lubricating system combining forced lubrication and splash lubrication. The reliable lubricating system helps extend the service life of the power end.
