ELW440/446 Pump can be widely used in all kinds of worksin oil field. When the cylinder liner specification is 6”-3 1/2”, pistonstructure is recommended and it is suitable for Oil-Well Repair andshallow-well drilling, etc. When the cylinder liner specification is 3 1/4”-2”,axial piston structure is recommended and it is suitable for high-pressurework.

Supreme liner(bi-metal liner) for EWS446 triplex piston pump has zise from3-1/2" to 6". With alloy steel outer shell and over 27% chrome inner sleeve.
The bore hardness is60 to 65 RC while the hull has high tensile strength of more than 90000psi. Allhy-chrome liner are manufactured with an “HP” lip in case of inner sleeveslippage.
Theservice life of this liner is more than 800 hours under normal drillingconditions. Eastland’s hy-chrome liners are made for superior performance undertough corrosive and abrasive conditions.
Valve & Seat
ESW446 piston pump uses API4# full open valve & seat with forged alloy struction,deep curburized wear
surface and greater fluid flow and easier maintenance and seat pulling.
Eastland offers replacement rubber piston,rubber bonded piston,urethane replacement piston and urethane bonded piston which allows to work under different drilling condition.
Size from 3" to 7-1/2".
