Pump Suction Specific Speed
Many times we come across the term pump suction specific speed (Nsss) during design and pump selection stages. If you wonder why this term most widely used in pump design or selection, then this article will help you to understand it. Suction Specific Speed It's a dimensionless number and index relating the flow, Net Positive Suction Head required (NPSHr) and speed for pumps. … [Read more...]
Centrifugal Pump System Curve and Pump Operating Point
In this article, we will see the Centrifugal Pump System Curve and Pump Operating Point. The system curve is a very basic element to finalizing the pump operating point ie., flow and head requirement. Pump System Curve Pump system curve represents the resistance offered by the system ie., the pressure developed by the pump is high enough to overcome the resistance offered by … [Read more...]
Centrifugal Pump Impeller Tip Speed – Calculation, Significant, Limitation
In this article, we will learn about the Centrifugal Pump Impeller Tip Speed – Calculation, Significant, Limitation. The impeller tip speed plays a vital role in the centrifugal pump handling liquid containing solid particles. Engineers to take extreme care to check the impeller tip speed during the engineering phase. The improper selection may lead to the continuous problem … [Read more...]
Mechanical Seal Vs Gland Packing
In this article, we will see the difference between the mechanical seal and gland packing (Mechanical Seal Vs Gland Packing). Although mechanical seals had been around for many decades and now it replaced gland packing in many application. But still, gland packing’s are used in many applications such as fire water pumps, effluent water pumps, valve packing’s, etc, [To … [Read more...]
