Gear Pumps

Gear Pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications.

Gear pumps are also widely used in chemical installations to pump high viscosity fluids. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gears (internal spur gear teeth face inwards, see below). Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.

Features:

l Only two moving parts

l Only one stuffing box

l Non-pulsating discharge

l Excellent for high-viscosity liquids

l Constant and even discharge regardless of pressure conditions

l Operates well in either direction

l Can be made to operate with one direction of flow with either rotation

l Low NPSH required

l Single adjustable end clearance

l Easy to maintain

l Flexible design offers application customization
