FT Split Series
Available in 800, 1300, and 1600 horsepower configurations.
Technical Description
▶ Gear pair Integral herringbone gear transmission provides high torque capacity and smooth operation.▶ Frame Fabricated from welded steel plates and annealed after welding. Necessary oil reservoirs and oil passages are arranged inside the frame. Due to weight limitations on the frame modules, a split structure is adopted.
▶ Crankshaft Made of alloy steel, with double-row self-aligning spherical roller bearings at both ends.
▶ Pinion shaft Made of alloy steel forgings, with herringbone teeth machined on the shaft. Both shaft extensions can be fitted with transmission devices.
▶ Crosshead Integrally cast from nodular iron, providing good wear resistance.

▶ Fluid cylinder Made of alloy steel forgings and available in two structural types: I-type and L-type. The I-type fluid end features a compact structure, while the L-type is easier to maintain.
▶ Lubrication system A combination of forced lubrication and splash lubrication is adopted. An externally mounted motor-driven oil pump can also be used according to user requirements.
▶ Spray system A centrifugal pump supplies cooling liquid to the cylinder liners. It can be belt-driven by a pulley mounted on the main pump transmission shaft, or driven independently by an electric motor.
▶ Jib crane system Installed on the frame for use when dismantling and replacing fluid-end components such as cylinder liners. It helps reduce the labor intensity of drilling workers.
▶ Safety valve Two options are available: shear pin type safety valve and spring-reset safety valve.If you have any special requirements for mud pumps, please contact Rongsheng’s technical staff.
