A solid and compact structure, miniature volume, good and reliable performance, which can meet the drilling requirements such as high pump pressure and big displacements in the oil field. F series mud pump has a longer stroke and can be operated at a lower stroke, thus improved the water supplying performance effectively and extended the lifetime of expendable parts in the fluid end greatly. The suction pulsation dampener has an advanced structure which is reliable to use and can make the pump realize its best suction performance. The power end uses combined lubricating system of forced lubrication and splash lubrication. Reliable to lubricate and promote the service life of power end. This series mud pumps are widely used in the oilfields and other industrial mining enterprises for well drilling and well repairing etc. This series mud pump are strictly manufactured according to API Spec 7k “the Equipment Specification of Well Drilling and Repairing”, and are tested accordingly when leave factory.
