Power pumps are used in a variety of applications where high-pressure and low-flow requirements exist. They are also widely used when a high-volumetric efficiency is

required. For these applications, other types of pumps have design or operating deficiencies that make their lower initial cost or lower maintenance costs less attractive. Some of the common applications for power pumps include the following:

The following applications may require power pumps with special modifications, and the exact requirements should be reviewed in detail with the pump supplier:

Duty Service To make an economical pump selection, the type of full-load service that you need should be considered. For instance, a small, lighter weight pump operating at higher speeds may be suitable for an intermittent duty application such as hydrostatic testing. The different types of duty services are as follows:

• Continuous: 8 to 24 hours per day

• Intermittent: Up to 3 hours per day

• Cyclic: 30 seconds loaded out of every 3 minutes
