F Mud Pumps
·Long stroke enables operation under low speed to lengthen the use of vulnerable parts at the fluid end

·Forced lubrication combined with splash lubrication makes the lubrication effective

·Advanced structure is durable ensuring smooth operation and meeting the special requirements of customers to drill medium deep wells

·Compact, safe, suction valve and discharge valve are interchangeable, main components of hydraulic cylinder and fluid end on each pump are interchangeable

·Durable fluid end greatly improves the performance of triplex mud pump; furthermore, its independent structure makes examination and maintenance convenient
Features of Series 3NB Mud Pumps：

·Dynamic End:  the frame is a welded structure with steel plate subject to post welding internal stress relief.  The type of transmission gear is involute, smooth running, efficient, and durable. Crankshaft is one-piece hollow cast and is splash lubricated

·Fluid End:  suction flange and discharge flange conform to ASA and API specification

·Piston rod and extension rod are connected by clamp to make assembly and disassembly easy and quick

·Bench at the bottom of valve positioning hole prevents valve seat sinking. Piston and cylinder liner are cooled and lubricated by independent spraying pump device for longer service life

·Vulnerable parts are interchangeable
