■ This pump consists of the fluid end and power end, its discharge pressure is high and has the extensive applications.

■ Power end: Adopts the worm gear reduction, which has the larger torque and higher input power, discharge pressure and output power. Such design makes it easier to be distributed both on the deck and the skid.

■ Fluid end: The surface of the plungers is covered by the hard, worn-resistant, and erosion-resistant alloy layers, which makes it last longer. The fluid end contains the separate valve sections whose volume is small. Such characteristics facilitate the operators to disassemble, assemble and conduct the maintenance, esp. for the field well application and offshore platform well application.
