1 day ago · Positive-displacement pumps represent a small but significant portion of the world of pumps which also includes dynamic-displacement—mainly centrifugal—pumps, which are by far the larger slice. Although positive-displacement pumps were once the mainstay for pumping fluids of any kind, centrifugal pumps have taken on much of the low-pressure, high-volume . Flowserve's positive displacement pumps product portfolio is one of the most comprehensive in the flow control industry. Explore a wide range of positive displacement pumps today.
Positive Displacement Pump Basics

Positive Displacement Pumps are designed to maintain a consistent flow for the contents inside without focusing on the pressure of the contents. Viscosity & High Solids Content are two of the major reasons to install Positive Displacement. Pumps. They are designed specifically to pump thick and. Positive displacement pump is a collective term for all pumps operating according to the positive displacement principle. These pumps are also referred to. Mark Ludwigson. Page 2 of Course Outline: What is a Positive Displacement Pump? Pump Types. Reciprocating Pumps. Rotary Pumps. Pump Design Steps.
A Positive Displacement Pumps is a "constant flow machine" A Positive Displacement Pump must never operate against closed valves on the discharge side of the pump - it has no shut-off head like Centrifugal Pumps. A Positive Displacement Pump operating against closed discharge valves continues to produce flow until the pressure in the discharge line is increased . Mar 17, · Positive displacement pumps are typically used to pump high viscosity fluids such as oils, paints, resins or foods. They are preferred in any application where precise metering or high pressure output is required. Unlike centrifugal pumps, the output of positive displacement pumps is not affected by pressure, so they are also often preferred in any . Continuous-Duty Any-DirectionConstant-Flow-Rate Pumps for Water and Coolants. Rated for continuous use, these pumps are often used to move caustics such as antifreeze and salt water. Mount them in any position, even upside down. Also known as diaphragm pumps, they are typically used for low-flow spraying, draining, and washdown applications.

Also known as diaphragm pumps, they are typically used for low-flow spraying, draining, and washdown applications. Positive displacement pumps add energy to a fluid by applying force to the liquid with a mechanical device such as a piston or plunger. A positive displacement pump decreases the volume containing the liquid until the resulting liquid pressure equals the pressure in the discharge system. That is, the liquid is compressed mechanically, causing a direct rise in potential energy.
