N32 and N46 freezing lubricating oil or other types of lubricating oil are used for conveying ammonia or fluorine machine, the temperature is 10°C to 80°C, the viscosity is 5 to 1500cst, it can convey pressure injection fuel pump in the fuel oil system, and can be used as lubricating oil pump in all industrial areas.
Gear uses the new technique that has the international advanced level in 80s’ to be round arc sin curve dentition. Compared with involute gear, that there is no relative sliding on the outline surface during the period of intersection is the most outstanding merit. So there is no abrasion on the surface, running balance, no rudimental liquid phenomena, little noise, long natural life and high efficiency. The pump gets rid of the tie of the traditional design, so it enters into a newfield including design, production and use.
There are two designs for the airproof of axes end, one is mechanicalairproof, the other is stuffing airproof.
