In an Internal Gear Pumps , a gear with internal teeth meshes with a gear with external teeth. These pumps are available with or without a crescent-shaped diaphragm. Regardless of the direction of rotation of the shaft, designs that provide the same flow direction can be used.
The disengagement gear on the inlet side draws liquid into the pump. The mechanical contact between the gears forms part of the dynamic seal between the inlet and outlet. The meshing of the gear forces the liquid out of the discharge port.
The relatively low speeds and inlet pressure requirements of pumps often make them a more efficient alternative to centrifugal pumps, especially as liquid viscosity increases. These designs have proven to be reliable, easy to operate and easy to maintain.
Roughly shown that commercially available internal gear pumps can provide flow rates of 1–400 m3 / h and exhaust pressures of up to 40 Barg (sometimes higher). Pumps usually contain at least one bushing in the liquid. They can be damaged when pumping large solids.
Pinion driven internal gear pumps are a unique sub-category with unique operating characteristics. They are usually direct-drive devices that operate at bipolar, quadrupole, and hexapole speeds, and are often used to remove to very light wear, low viscosity liquids, such as hydrocarbon-based liquids. They are designed in single-stage or multi-stage modules and are capable of withstanding 200 Barg (sometimes higher).
As a professional China internal gear pump manufacturer and supplier. Zhejiang Yongling Hydraulic Machinery Co., Ltd. produces and supplies YLH series internal gear pumps with high working pressure, high volumetric efficiency, low pressure pulsation, low noise, wide speed range, and strong anti-pollution ability.
