Importance of selection of centrifugal pumps

The pump therefore converts mechanical energy from a motor to energy of a moving fluid. Abrasive or Non-abrasive 2. Unnecessary safety margins are added and thus resulting in huge Capital Cost.

Rotation speed is rpm. Most centrifugal pumps are not self-priming. The pump volumetric efficiency has to be found. Contact us today for assistance with pump selection, or general questions concerning pumps and other fluid handling equipment.

Often buyers purchase oversized pumps with various misconceptions. The pump is actuated by electric motor having power of 9.

Mechanical seals are used where leakage is not permitted. Flow is varied by varying air pressure supplied to the pump. The Nature of fluid is very important to know before selecting a pump. Head friction losses in pipes and local resistances equal to Flow is varied by varying the pump speed.

Please send your requests for pumps to the technical department of our company to E-mail: The value we obtained does not fall within this interval, wherefrom one may conclude that in operation of this pump under set conditions problems can arise when starting it up. Lubrication type of the pump is also critical in many cases where clean water is not available and oil lubricated pumps are desired.

Various steps are taken before concluding on the pumping equipment. Diaphragm type pumps are generally deployed within the following ranges: Surge or back surge in the line.

Excessive increase of pressure differential may result in the occurrence of cavitation — process when pressure drops down to value at which fluid boiling temperature lowers below pumped medium temperature and it starts to evaporate in flow space forming multiple bubbles.

Importance of right pump selection

With many different configurations available, centrifugal pumps are widely-used because of their design simplicity, high efficiency, wide range of capacity and head, smooth flow rate and ease of operation and maintenance.

Performance of a Centrifugal Pumps largely depends on a correct specification and selection.This tutorial is intended for anyone that has an interest in centrifugal pumps. There is no math, just simple explanations of how pump systems work and how to select a - How to verify that your centrifugal pump is providing the rated pressure or head?

- What is density and specific gravity and how do they relate to pressure and head? CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid.

Centrifugal pumps are commonly used to move liquids through piping. 7 Essential Variables For Pump Selection. Author: Dale Annoye | July 22, or general questions concerning pumps and other fluid handling equipment.

Our staff of degreed Engineers are happy to provide technical assistance to businesses in Wisconsin and upper Michigan.

Does Pressure Pulsation from your Centrifugal Pump Cause Damage. Centrifugal pumps can be used in many applications, but in order to operate reliably, with optimal energy use and maximum life span, a pump's design characteristics must suit the intended service.

Main principles of pumps selection. Calculation of pumps

Correct pump selection is the first step to ensure this, as Eduardo Larralde and Rafael Ocampo demonstrate in this first of two articles. 0 3 Flow Rate · Head · Efficiency · Input Power 3 Selection for Pumping Water This section applies mainly to pumping water; the particulari­ ties of pump selection for other media are treated in sections 4.

Aug 06,  · 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.
