Pump Characteristic Curve Unlike centrifugal pump, Rotary pump do not generate pressure. Instead it works against the back pressure of a given system. The characteristic of the curve is very dependent on the liquid properties especially the viscosity of the liquid. The speed of the pump at a given viscosity will also play a role …
Cavitation Cavitation is a serious operational-type problem that takes place where there is insufficient suction pressure to meet the NPSH requirements of the pump. “Cavitation” implies a dynamic process of formation of bubbles inside the liquid, their growth and subsequent collapse (implosion) as the liquid flows through the pump. Cavitation results in loss of volumetric …
Pump Characteristic Curve Pump characteristic curve (or pump performance curve) determines the range of flows and energy produced for a fixed speed, size, design and suction conditions of the pump. The head / pressure (energy) produced by a pump must equal to or exceed the net head / pressure (energy) required by the system so …
Centrifugal Pumps Centrifugal Pumps are by far the most widely used of fluid handling pump types due to its design simplicity, durability, versatility and economics. More than 85% of all the installed pumps in any typical factories/plants are centrifugal pumps. The distinctive features and unique operating characteristics of centrifugal pumps will be further discussed below. A …

Positive Displacement Pumps A Positive Displacement pump is also known as the power pump and it operates by continuously deliver liquid flow but independent of the pressure in the discharge piping system. The discharge piping system produces resistance to this liquid flow, thereby generating pressure in the discharge piping system. Unlike centrifugal pump, it does …
What are pumps? In general, regardless of the type of pump, it is defined as a mechanical device or equipment that is used to: transfer or move liquid from one point to the other by imparting kinetic and potential energy to the liquid. built up pressure or pressurization purpose. Pumps can be further classified into …
