RESEARCH AND TECHNOLOGY

ations based on the principle of the centrifugal pump and consisting of the same basic hydraulic parts. The majority of pumps produced by are centrifugal pumps. 1.1 Principle of the centrifugal pump An increase in the fluid pressure from the pump inlet to its outlet is cre-ated when the pump is in operation. This pressure difference

Centrifugal pump - Wikipedia

To ensure that a centrifugal pump remains primed and does not become gas-bound, most centrifugal pumps are located below the level of the source from which the pump is to take its suction. The same effect can be gained by supplying liquid to the pump suction under pressure supplied by another pump placed in the suction line.

Centrifugal Pump KSB

The centrifugal force moves the fluid towards the outer edge of the pump impeller. As a result, the fluid is transported to the outlet opening of the pump. At the same time, a negative pressure zone is created at the inlet opening, which draws the fluid further and further into the centrifugal pump.

Submersible pump - Wikipedia

A submersible pump (or sub pump, electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface.

the main reason for using head instead of pressure to measure a centrifugal pump's energy is that the pressure from a pump will change if the specific gravity (weight) of the liquid changes, but the head will not; The pump's performance on any Newtonian fluid can always be described by using the term head. Different Types of Pump Head

PUMP BASICS How Centrifugal Pump. A centrifugal pump is of very simple design. The only moving part is an impeller attached to a shaft that is driven by the motor. The two main parts of the pump are the . impeller. and . diffuser. The impeller can be made of bronze, stainless steel, cast iron, polycarbonate, and a variety of other materials.

How a Self-Priming Pump Works PumpStoreUSA

When they operate on flooded suction lines or in submersible applications, the impeller is surrounded by enough water to create the pressure differential and thus to pump water. Air is the main enemy of a standard (non-self-priming) centrifugal pump. When the standard centrifugal pump encounters air, it can become air-bound.
