Crosshead and Extension Rod

Crosshead and Extension Rod of features Renewable crosshead guide. The crosshead and crosshead guide are made of ASTM A48-83 meehanite cast iron featured by good abrasion resistance and long service life. Upper and lower guides are used for F-800 and F-1000 mud pumps, so that the concentricity can be adjusted by adding shimes beneath the lower guide. F-500 mud pump is the cylindrical structure. The connection between the crosshead and the extension rod is made by using bolted flange. The rigid connection ensures the concentricity of the crosshead and the extension rod. The coupling is used for connecting the extension rod to the piston rod. The light-weight coupling enables the extension rod and the piston rod to connect to each other easily and reliably.
