A positive displacement (PD) pump moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms, or vanes.
Learn what a positive displacement pump is and how it works. Explore the different types of PD pumps, such as rotary, reciprocating, linear, and peristaltic pumps, and their advantages and disadvantages.
Learn the basic operating principles and types of positive displacement pumps, such as reciprocating and rotary pumps. Find resources, tools and basic information for engineering and design of technical applications.
Learn about positive displacement pumps, which move fluid at a steady rate through a system. Compare rotary and reciprocating pumps based on performance, flow rate, pressure, and liquid compatibility.
14 Ιουλ 2023 · Learn how positive displacement pumps work and the different types of reciprocating and rotary pumps. Find out the advantages, applications, and features of each pump type and compare them with centrifugal pumps.
Learn what a positive displacement pump is and how it works by trapping and forcing a fixed amount of fluid into a discharge system. Compare different types of positive displacement pumps, such as rotary, reciprocating, linear and diaphragm pumps, and their applications and benefits.
Learn about the types, characteristics, applications and selection criteria of positive displacement pumps, which are batch delivery devices that deliver fluid volumes with fixed displacement.
