The pillar fills is it suffer the one of the dint spare parts primarily. The slippery boots is one of the form that high pressure pillar fill the pump to often adopt. It can adapt to the high demand turning soon in high pressure dint, go together with the oil dish and the efficiency of the direct influence in a pump with life span. Because of going together with the oil dish fills ,pillar and a slippery boots these two rightness of high speeds the sport the vice- all adopting a the static pressure accepts. The province went to the big capacity push the bearings, have the construction tightly packed, the spare parts is little, the craft is good, the cost is low, the physical volume is small, the weight is light, comparing
