Gear pumps are commonly used for pumping high viscosity fluids such as oil, paints, resins or foodstuffs. They are preferred in any application where accurate dosing or high pressure output is required. The output of a gear pump is not greatly affected by pressure so they also tend to be preferred in any situation where the supply is irregular.

Gear Pump Basics. Displacement (D) – The displacement of a rotary gear pump is the volume displaced during one complete . revolution of the gears. It may be calculated from the physical dimensions of the gears, or it . may be determined as the volume of fluid pumped per revolution at zero differential . pressure.

pump. Because a gear pump cannot create a perfect vacuum, the total lift (including pipe friction losses) should not exceed about PSI, or onehalf of the atmospheric pressure. The tight clearances of the working parts inside a gear pump are what enable it to effectively pump liquids against high pressure. Low viscosity fluids such as

The pump selection of a pump is driven by the following main parameters: – Head (H) – Flow rate (Q) – Fluid characteristics (ρ, γ, T ..) Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity, so the relation is fluid dependent.

The head of the pump depends on the flow rate and it is zero at the maximum head and diminishes as the flow increases. To verify the discharge head of a pump, a pressure gauge is used. Pressure gauges measure in units called psi or pounds per square inch. The formula gives the conversion of pressure to head.

inversely proportional to the pressure at the pump outlet. In other words, the outlet flowrate of a rotodynamic pump varies nonlinearly with pressure. In a positivedisplacement (PD) pump, a discrete amount of fluid is trapped, forced through the pump, and discharged. A gear pump is an example of a PD pump (Figure 2). This

· Head is useful because it evaluates a pump''s capacity to do a job. Most pump applications involve moving fluid to a higher level. If you have to pump a liquid up 30 feet and your pump doesn''t have at least 30 feet of head, then there is no chance it will work.

Measures and conversion formulae are summarised in a table. The flow rate is the effective volume flowing per unit of time through the discharge connection of a pump. In order to optimize the pump design, the flow rate must be accurately determined. The total head is the effective mechanical energy transferred by a pump to the fluid as a

Many external gear pumps use journal bearings to support the rotating shafts. In order for these bearings to work, a minimum speed is required (depends upon pressure of the pump.) In addition to imposing limits on the operational speed, in many cases, the bearings determine the maximum pressure the pump .
