Bw Series Piston Mud Pump for Water Well Drilling Rig
Description of Piston Mud Pump
Mud pumps serve as the heart of the mud circulating system. Reciprocating piston pumps (also called slush pumps or power pumps) are widely used for drilling oil and gas wells. The advantages of the reciprocating positive-displacement pump include the ability to move high-solids-content fluids laden with abrasives, the ability to pump large particles, ease of operation and maintenance, reliability, and the ability to operate over a wide range of pressures and flow rates by changing the diameters of the compression cylinders (pump liners) and pistons.

Application of BW Bw320 Piston Mud Pump
The pump is mainly used for supplying flushing fluid to the borehole in the geological drilling process. It can match with big-diameter rigs in different drilling depths and improve drilling efficiency and borehole quality.
Features of BW Mud Pump
1. There are five dust-proof sealing rings on the tie rod to prevent the mud at the hydraulic end from being brought into the power end and the lubricating oil filter at the power end. It has been proved by many production tests that the sealing is reliable and the performance is good. Extend gear life.
2. The inlet and outlet valves use steel balls. And there is a sound-absorbing rubber pad on the valve cover to reduce impact noise.
3. Compact structure and beautiful appearance.
4. Good disassembly, easy maintenance, and relocation.
Working Process of BW Mud Pump
1. Inhalation process
When working, the power machine drives the main shaft and the crank fixed on it to rotate through transmission components such as belts, transmission shafts, and gears. When the crank rotates counterclockwise from left to right from the horizontal position, the piston moves to the 2. power end, the pressure in the liquid cylinder gradually decreases and a vacuum is formed. , until the piston moves to the right dead center.
Discharge process
After the crank completes the above-mentioned suction process, it continues to rotate in the counterclockwise direction. At this time, the piston starts to move to the hydraulic end, and the liquid in the cylinder is squeezed. The pressure rises, the suction valve is closed, the discharge valve is pushed open, and the liquid enters the discharge pipe until the piston moves to the left dead center.
