The two forms of the gear pump seal

Gear pumps are relying on the pump cylinder and the ring gear is formed between the working volume change and move to transport the pressurized fluid or the rotary pump. The two gears, pump and front and rear cover consists of two closed space, when the gear rotates, the gear disengagement-side small volume of the space becomes large, a vacuum, the liquid suction, the gear meshing side volume of the space from the drastic change small, and the liquid pipe to squeeze. Suction chamber and the discharge chamber is by two gears meshing lines separated. Gear pump discharge pressure at the outlet of the pump source resistance full size.
Gear shaft end seal design in two forms, one a mechanical security seals, and the other one is packing pull tight security seals, according to the specific use conditions and user requirements. Ninety one gear of an internationally advanced level of new technology - dual arc sine curve tooth arcs. It is compared with involute gear, the most prominent advantage is the process of meshing tooth profile surface without sliding, so no tooth wear, running balance, phenomenon of trapped liquid, low noise, long life and high efficiency. The pump is designed to get rid of the shackles of tradition, making the gear pump in the design, production and use into a new area.
Pump with pressure relief valve as overload protection, total reflux pressure relief valve discharge pressure of 1.5 times the rated pump. Also allow the discharge pressure range to be adjusted according to actual needs. But this can not be the safety valve valve long-term work, when necessary, be installed in the pipeline.
