Gear Pump Applications

Gear pumps are useful for industrial applications such as:
  • Petrochemical
  • Food
  • Chemicals
  • Paint and ink
  • Resins and adhesives
  • Pulp and paper

How Gear Pumps Work

Gear pumps are positive displacement rotary pumps that transport liquids using rotating gears. They function by using two or more internal gears that create vacuum pressure, propelling the fluid media. Gear pumps are compact, high pressure pumps which provide a steady and pulseless fluid flow comparable to double diaphragm pumps and peristaltic pumps.
Gear pumps are positive displacement pumps, meaning they use expanding and contracting chambers to move fluids at a fixed rate. Specifically, they are rotary positive displacement pumps, which utilize a rotating mechanism or assembly to cause this contraction and expansion. 
Gear pumps are the most common type of positive displacement pump used. Typically, a rotating assembly of two gears (a drive gear and an idler) moves to create suction at the pump inlet and draw in fluid. The liquid is then directed between the teeth of the gears and the walls of the casing to the discharge point. Volume decreases as the liquid travels from inlet to outlet, causing a buildup of pressure. Pressure relief valves are typically built-in to the pump to protect the pumping system from a closed valve in the discharge piping. Flow in gear pumps is determined by the size of the cavity (volume) between the gear teeth, the speed of rotation (rpm) of the gears, and the amount of slippage (reverse flow). Slip increases as the pump wears.
