WHAT IS PUMP EFFICIENCY?
When we talk about the efficiency of most types of machines, we are usually referring to how well it can convert one form of energy to another. If there is one unit of energy supplied to the machine and its output, in the same units of measurement, is one half unit, the efficiency of it is 50%.
WHAT IS SPECIFIC SPEED? HOW DOES IT AFFECT THE PUMP CURVE?
Specific speed was first applied to centrifugal pumps and was then a modified version of one developed for water turbines.
You will find that most pump designers tend to see specific speed as the most important contributor to centrifugal pump design, allowing the use of existing design and the test data to design similar higher and lower flow pumps as the specific speed of a pump is independent of the size.
HOW DOES THE CURVE SHAPE OF A PUMP AFFECT ITS EFFICIENCY?
The typical performance curve is basically flat at low values of specific speed and it will become steeper as the Ns increases. The pump efficiency is lowest at low values of Ns and it will increase as the Ns increases.
It reaches the max in the mid-to-high 2000 range and it will also begin to decrease above 3000.
HOW DO MULTICUTTERS HANDLE SOLID MATERIALS?
The system keeps itself protected thanks to cutter blades that reject any material, such as stones or metal, that the system is unable to cut.
