Abstract
A hydraulic end and a fracturing pump. The hydraulic end includes a body and a functional device. The functional device includes at least one of a base plate, an end cover assembly, and a packing assembly, and the functional device is detachably fixedly connected to the body. The above hydraulic end can solve the problem of relatively high production costs caused by replacement of an entire hydraulic end body in case of failures such as leakage caused by wear of a packing or cracking of an end cover under a force.
