The invention provides a pump body assembly and a compressor with the same. The pump body assembly comprises two structural members, a cylinder, a rotating shaft, a plurality of sliding pieces and at least one friction reducing structure; the air cylinder is arranged between the two structural members; the rotating shaft penetrates through the two structural members and the air cylinder, a plurality of sliding piece grooves are formed in a rotor part of the rotating shaft, and the multiple sliding pieces are slidably and correspondingly arranged in the multiple sliding piece grooves; and the friction reducing structures are arranged between at least one structural member and the air cylinder to prevent contact friction between the air cylinder, the rotor part and the multiple sliding pieces and the structural members. The pump body assembly effectively solves the problem that reliability of the pump body assembly is reduced due to the fact that the internal structure of a pump body assembly in the prior art i
