6. Power pumps: A picture of a power pump is shown in Figure 2.6. Power pumps are used normally for high pressure, low flow applications, typically carbonate, amine service or high-pressure water or oil services. They can either be horizontal or vertical. The major parts of a power pump as shown in Figure 2.6 include the liquid cylinder with pistons and rods, the valves and power end. The power end consists of the crankshaft with bearings, connecting rod and crosshead assembly. It is termed. Power Pump' because it is driven by an external power source, such as an electric motor, or internal combustion engine, instead of steam cylinders as in direct-acting pumps.

7. Diaphragm pumps: A schematic of a diaphragm pump is shown in Figure 2.7. In this type of pump, the power end and liquid end areas are approximately the same. This results in the pump being capable of pumping against pressures no greater than that of the motive fluid. This pump has limited use in the refining and petrochemical industry and is used primarily for metering services.

8. Screw pumps: Figure 2.9 illustrates the screw pump design. Fluid flow is carried axially between the threads of two or more close clearance rotors so that a fixed volume of fluid is displaced with each revolution. This design is frequently used for lube and seal service.

9. Gear pumps A picture of a commonly used gear pump is shown in Figure 2.10. With this type of pump, fluid is carried between the teeth of two external gears and displaced as they mesh. Gear pumps are used for small volume lube oil services and liquids of very high viscosity (asphalt, polyethylene, etc)

10. Single stage overhung pumps: The single stage overhung pump design shown in Figure 2.12 is probably the most widely used in the industry. Its construction incorporates an impeller affixed to a shaft: which has its center of gravity located outside the bearing support system.
