Mud pump piston seal



Rubber drum seal; double acting fluid seal The cross section is a drum shape, also known as a piston seal ring, designed for one-way and two-way action pistons. According to the use requirements, there are different cross-section structures, but they are all composite elastic seals made by NBR and tape directly molded. When using the tape, two plastic retaining rings or L-shaped bushings must be applied to ensure the initial sealing by pressing the lip of the sealing lip and compressing the cross-section to press the lip against the sealed surface. This type of seal is particularly suitable for large hydraulic lift plugs, stable hydraulic cylinders, etc., which allow a working pressure of up to 75 MPa and a line speed of 0.5 m·s-1.
