Rod Baffle
Pump Parts
A Rod Baffle guides the flow of drilling mud around the piston rod as it moves back and forth within the Liner of the mud pump. By doing so, the rod baffle helps to reduce turbulence and wear on both the piston rod and the liner. The Rod Baffle serves as a flow director, ensuring that the drilling mud is evenly distributed around the piston rod during the pump's operation. This placement on the piston rod is crucial for maintaining the efficiency and longevity of the mud pump.
