Gear Pumps Supplier

Order Positive Displacement Pumps for High-Pressure Pumping

Gear pumps are a type of positive displacement pump that utilize interlocking cogs and gears to mechanically moves fluids in smooth, repeatable volumes. Pumping Solutions carries the internal and external gear pumps you need for your operations that involve viscous materials. These pumps come in various sizes, materials and flow rates to meet multiple fluid transfer applications. As a trusted distributor of pumps from industry-leading brands, we are confident that we can deliver quality pumps and pump parts faster than our competitors. We offer pumps for lubrication/circulation and magnetically couple gear pumps.

Benefits of Gear Pumps

Gear pumps offer a versatile solution for pumping oils and high-viscosity fluids. The exact benefits of gear pumps vary depending on the model and composition, but general advantages include:
  • Steady Flow Rates
  • Accurate Dosing
  • High-Pressure Output
  • Self-Priming
  • Easy to Maintain
  • Compact Size

Gear Pump Applications

Gear pumps can efficiently pump high viscosity fluids and oils, as the rotating gears generate high enough pressure and suction to consistently transfer liquids at steady flow rates. Gear pumps can even transfer fluids ranging in temperature depending on the application and environment. Gear pumps can pump paint, ink, resins, adhesives, chemicals, solvents, food products and more at high pressures while still maintaining precise output. Because gear pumps have very few moving components, they are ideal for applications requiring high-volume pumping with little maintenance requirements.

How Gear Pumps Work

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. They function by using two or more internal gears that create vacuum pressure, propelling the fluid media.
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.

Gear Pumps for Multiple Industries

Gear pumps are typically compact and economical, and provide accurate dosing that is suitable for a variety of industries. Gear pumps are useful for industrial applications such as:
  • Petrochemical
  • Food
  • Chemicals
  • Pulp and paper

Why Choose Gear Pumps Over Diaphragm & Peristaltic Pumps

Gear pumps, diaphragm pumps and peristaltic pumps are micro-liquid pumps that are widely used in chemical processing, wastewater treatment, medical applications and more. These pumps each have a unique design and structure that impacts performance, pressure, flow rate and cost performance, all of which should be considered prior to selecting your pump design. Gear pumps provide a steady and pulseless fluid flow and low noise comparable to double diaphragm pumps and peristaltic pumps. Gear pumps are typically more compact, reliable and simple in design for lower maintenance costs than peristaltic and diaphragm pumps. However, gear pumps do not offer the sanitary qualities of a peristaltic pump or the high flow and corrosion-resistant qualities of a diaphragm pump.

External & Internal Gear Pumps

External Gear Pumps

External gear pumps utilize two interlocking gears of the same size supported by separate shafts. External gear pumps are capable of sustaining higher pressures and flow rates, and can be used in hydraulic power applications.

Internal Gear Pumps

Internal gear pumps are designed similar to external gear pumps, but internal gear pumps utilize gears of different sizes, with one rotating inside the other. Internal gear pumps have better suction and are suited for high-viscosity fluids in metering and blending applications.
