Fundamentals Of Pumps

Fundamentals Of Pumps

Centrifugal pumps can be classified based on the manner in which fluid flows through the pump. The manner in which fluid flows through the pump is determined by the design of the pump casing and the impeller. The three types of flow through a centrifugal pump are radial flow, axial flow, and mixed flow. Radial Flow Pumps

Back to Basics Pump Sizing - AIChE

In a positive-displacement (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 pumping principle produces a pulsating flow, rather than a smooth flow. Its output flow tends to vary little with respect to the pressure at the pump outlet, because the moving

Rotary pumps use a variety of means to generate flow. A pair of gears with many teeth (external to the gear and called an external gear pump) in gear pumps or a few lobes in lobe pumps is demonstrated in Fig. 23.2.Internal gear pumps use a gear within a gear design; internal means the teeth of one gear are on the inside, projecting inward. Gear pumps are useful for pumping viscous liquids or .

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from .

Flat plate type vacuum pumps have a port plate configuration rather than a cone, but the working principle is the same. Above figure shows construction (exploded view) of a typical flat plate type vacuum pump. The flat plate type design is easier to manufacture. However, the flat plat type design is less efficient then the cone type design. Piping

Depending on pump design, the vacuum limit ranges from 28 to 29.5 in.-Hg or about 93% or 98% of the maximum theoretical value. For some pump types, the maximum vacuum rating will be based on this practical upper limit. For others, where heat dissipation is a problem, the maximum vacuum rating might also take into account allowable temperature rise.
