What is a Rotary Gear Pump?
A rotary gear pump is a form of positive displacement pump in which fluid is moved by the rotation of meshing gears. The term ‘rotary’ distinguishes it from reciprocating pump types. It is widely used for transferring oils, chemicals, and high-viscosity fluids efficiently.
How It Works
As the gears rotate, they unmesh on the inlet side, creating a low-pressure zone that draws fluid in. The fluid is carried between the gear teeth and the casing to the outlet, where the gears mesh again and force the fluid out under pressure.
Rotary Gear Pump with Motor
A rotary gear pump with motor is a compact, integrated solution where the pump is directly coupled to an electric motor on a common baseplate. This configuration is popular in skid-mounted lube oil systems, hydraulic power packs, and fuel dispensing units.
Key Advantages
Rotary gear pumps offer constant, pulsation-free flow, self-priming capability, bidirectional operation, and the ability to handle viscous fluids up to 100,000 cSt. They are compact and mechanically simple, resulting in lower maintenance requirements.
Choosing the Right Manufacturer
When selecting rotary gear pump manufacturers in India, look for those offering material options (CI, SS, hardened steel), pressure ratings up to 200 bar, and compliance with IS/DIN/API standards. Application-specific customisation is a strong indicator of a capable manufacturer.
