Comparing Four Types of PD Pumps (Copyright Viking Pump, Inc.)
, particle size in the liquid, abrasive characteristics, and corrosiveness of the liquid must be determined before a pump selection is made. A pump needs proper suction conditions to work well. PD pumps are self-priming, and it is often assumed that suction conditions are not important

Hydraulic Pumps
the pneumatic system power the hydraulic circuit, without requiring a new prime mover. Because these devices are directly competitive with pumps on some jobs, and complementary on others, they are included in this section. Most hydraulic pumps receive fluid from a reservoir and pump it to a loaded actuator

, and the project will face additional challenges. As an example, a typical customer may ask for a diesel driven 6 inch pump capable of pumping 1400 gallons per minute (GPM). Well, there are multitudes of pumps that will meet this requirement. Just because it's a 6-inch pump doesn't mean it's equal

Positive-displacement pumps, when slowed down, do not serve well as air compressors, particularly if forced to discharge into a system where the pressure is controlled by a regulator set for burner pressures. An air vent or bleed will help get rid
