Gear pump is a rotary pump that relies on the change and movement of the working volume formed between pump cylinder and the meshing gear, to transport liquid or pressurize it. The main applications of gear pumps are hydraulic transmission, mechanical engineering and so on. In terminology, a gear pump is also called a positive displacement device, which is like a piston in cylinder. When one tooth enters the fluid space of another tooth, because the liquid is incompressible, the liquid and the tooth cannot occupy the same space at the same time. In this way, water or other liquids are mechanically squeezed out.
On the point of structure, gear pump is divided into external gear pump and internal gear pump. In terms of materials, gear pumps include aluminum alloy gear pumps, stainless steel gear pumps, cast iron gear pumps, plastic gear pumps, brass gear pumps, etc.
Gear pump has the advantages of compact structure, small size, light weight, low price, strong self-priming, insensitive to liquid pollution such as fuel, large speed range, impact load resistance, and simple use. Gear pumps cannot be used as metering pumps. ATO provides hydraulic gear pumps for sale, single/tandem/triple working pump, please visit the catalog.
