Features

1)Power end features
    Continuous tooth herringbone gear. One-piece alloy steelcrank. Renewable crosshead guide. The frame is made of welded steel plate toprovide the frame with high strength, good rigidity and lightweight. Theextension rod packing is of duplex seal structure to provide the good sealresult.
