Positive Displacement (PD) and Metering
| Positive Displacement Pumps (PD) are used in applications that required constant and stable flow of liquids. The material flow for these types of pumps are easily regulated by changing the speed of the pump. They can produce high pressures with minimal suction forces and are very efficient with higher viscosity materials. There are several types of PD pumps including progressing cavity (PCP), screws, gear, pistons and diaphragms. |
