Mud pumps are used to circulate drilling fluids,cleaning bottom of the hole,carry the drill cuttings out of the hole,cool,clean and lubricate the bit,and support the wall in drilling operation in oil and gas field,are a kind of horizontal medium-speed triplex single-acting piston pump.It is especially suited to high press- ure jet drilling for increasing penetration rate,and it can also supply flowing drilling fluids for downhole motors to drive the downhole drilling machines and downhole tools.
3NB series mud pumps are composed of the power end and the fluid end.The power end includes the following parts such as:frame,a drive shaft,a driven shaft,a transmission shaft of lubricating oil pump,and a lubricating system.The fluid end includes the following parts such as:valve pots,liners and pistons,high pressure manifolds, suction manifolds.
3NB mud pumps series are 3NB—500, 3NB—800, 3NB—1000, 3NB—1300, 3NB—1600
