A one of its kind, Positive Displacement Pump was designed long before centrifugal pumps. These pumps are extremely capable of not being affected by the pressure against which it operates. Positive Displacement Pumps apply force to the liquid with a mechanical device resulting in addition of energy to thefluid. Plungers, Piston, Diaphragm, Screws, Rollers, Vanes and Gears are some of the important mechanical parts of Positive Displacement Pump. They all together act like a syringe and capture the moving fluid by expanding cavity at the suction side, and then discharge the required amount of fluid by decreasing cavity at the discharge side. There are three types of Positive Displacement Pumps and the most important factor that differentiates these types from one another is the distinctive mechanism used to move the fluid in each of these types.
Rotary Type Rotary Vane Gear Pump Screw Pump
Reciprocating Type Circumferential Piston Plunger Diaphragm Piston
Linear Type Chain Pumps Rope Pumps These pumps are quite apt at working and expanding in high pressures while simultaneously working at little suction forces which is why they are also commonly called as constant volume pumps. Unlike centrifugal pumps, the capacity of the Positive Displacement Pumps is not affected by force which is why they are generally used in industries with low flow applications and where high maintenance costs are more than offset by their higher efficiency. The important elements that sets apart positive displacement pumps from the others is the fact that they work for high force applications, so as the pressure increases so does its efficiency, and when the pressure changes so does its flow.
