As there is a certain gap between the spool ring and the pump chamber, the pump chamber and the slide valve outside the park are not easy to wear. 2 pump at ambient temperature 5-40 ° C range, the maximum oil temperature measured at the filler hole 3 pump is not suitable for pumping high oxygen content, toxic, explosive, corrosive to the metal, The gases that chemically react with the pump oil and contain particulate dust are also not suitable for transporting gas from one container to another for use as a transfer pump. If necessary, to be fitted with a good effect, easy to clean the dust filter and other accessories. 4 pump continuous work of the highest entrance pressure and time, it is recommended when 133pa
