  • Gear Pumps- Gear Pump

    A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for pumping oil. Gear pumps are also widely used in chemical installations to pump fluid greater viscosity. There are two main variations; external gear pumps which use two external spur or helical gears, and internal gear pumps which use an external and an internal spur gear.
