Modular External Gear Pump
Our Modular External Gear Pump is a robust solution tailored for the Oil & Gas industries. This pump shares similarities with Internal Eccentric Gear Pumps, featuring only 2 moving components within the process medium. This pump operates based on the ‘gear within gear’ principle. In this design, the rotary and idler gears in the pump head create cavities between their teeth, achieving positive displacement. With each revolution, a fixed volume of fluid enters the casing through the suction port, filling the spaces between the gear teeth. The crescent within the pump head efficiently separates the fluid as the idler gear turns on the pump shaft.
Typical industries and applications for our Modular External Gear Pump:
- Fuel Oil, Gas Oil, Diesel-Fuel Tanks
- Hot Oil Circulations (small scale)
- Semi-Viscous Fluids
- Dye Industry
Features & Benefits
- ATEX available
- Accurate & pulseless flow at high differential pressures
- Ability to pump fluids too viscous for centrifugal pumps
- Higher differential pressures than centrifugal pumps
- High mechanical efficiency across different pressures and varying flow
- Efficient suction lift applications
- Ability to operate at different points on their curves as flow is proportional to rotational speed and pressure is dependent on the installed motor power
- Bi- Directional pumping action
