Our P series single acting triplex mud pumps are featured by its compact structure, small weight and high efficiency; they are durable and compact and can ensure stable operation.

During shallow/middle to deep well drilling, the P series mud pumps can meet the special requirements of users.

The durable fluid end of P series mud pumps significantly increases the performance of three cylinder mud pumps. In addition, the independent structure is easy to inspect and maintain.

Features of Power end in P Series Mud Rumps

·         The base of machine frame adopts one-piece welded structure and the seats of main bearing and transmission bearing are made of one-piece cast steel. The whole pump has good stiffness and strength.

·         The crankshaft adopted a mosaic structure of alloy steel forge with full balance, so that it operates very smoothly.

·         The pinion shaft is made of an integral structure and belt pulley or chain wheels may be installed on wither or both side of the shaft.

·         Roller bearings are installed at both ends of the shaft in order to improve the stability in operation and bearing capacity.

·         The gears and crossheads of the bearing are lubricated by splash methods.

·         The integral herringbone gear structure is adopted to ensure that the pump operates smoothly.

·         The extension rods are connected to the crossheads by pin holes, so as to ensure the concentricity of the pump. The packing adopts quad layer sealing structure, which realizes good seal performance.

Features of Fluid end in P Series Mud Pumps

·         The hydraulic cylinder is deployed in an L form so as to keep the liquid flow stable and to reduce vibration and pressure fluctuated.

·         The combined hydraulic cylinders are interchangeable and may be replaced individually.

·         The fast rotary valve cover is easy to remove and install. The cone bolts have a self-locking mechanism which helps to reduce vibration at the valve cover and to ensure the fastening and stability.

·         The piston rod and intermediate rod are joined by clamps, which is easy to remove and replace.

·         The combined piston rod allows replace of pistons without need to disassemble the liners.
