What is a centrifugal pump?<\/h3>

A\u00a0centrifugal pump\u00a0is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers.\u00a0 Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller\u2019s vane tips.\u00a0 The action of the impeller increases the fluid\u2019s velocity and pressure and also directs it towards the pump outlet.\u00a0 The pump casing is specially designed to constrict the fluid from the pump inlet, direct it into the impeller and then slow and control the fluid before discharge.<\/p>

How does a centrifugal pump work?<\/h3>

The impeller is the key component of a centrifugal pump.\u00a0 It consists of a series of curved vanes.\u00a0\u00a0<\/p>

\"\"<\/p>

Fluid enters the impeller at its axis (the \u2018eye\u2019) and exits along the circumference between the vanes.\u00a0 The impeller, on the opposite side to the eye, is connected through a drive shaft to a motor and rotated at high speed (typically 500-5000rpm).\u00a0 The rotational motion of the impeller accelerates the fluid out through the impeller vanes into the pump casing.<\/p>

There are two basic designs of pump casing: volute and diffuser.\u00a0 The purpose in both designs is to translate the fluid flow into a controlled discharge at pressure.<\/p>

Centrifugal pumps are commonly used for pumping water, solvents, organics, oils, acids, bases and any \u2018thin\u2019 liquids in both industrial, agricultural and domestic applications.<\/p><\/blockquote>

What are the limitations of a centrifugal pump?<\/h3>

The efficient operation of a centrifugal pump relies on the constant, high speed rotation of its impeller.\u00a0 With high viscosity feeds, centrifugal pumps become increasingly inefficient: there is greater resistance and a higher pressure is needed to maintain a specific flow rate.\u00a0 In general, centrifugal pumps are therefore suited to low pressure, high capacity, pumping applications of liquids with viscosities between 0.1 and 200 cP.<\/p>

Slurries such as mud, or high viscosity oils can cause excessive wear and overheating leading to damage and premature failures. Positive displacement pumps often operate at considerably lower speeds and are less prone to these problems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
