Understanding Suction Specific Speed
The Suction Specific Speed of a centrifugal pump is a dimensionless number that characterizes the pump's hydraulic performance. It is defined as the speed at which a geometrically similar pump would operate if it were of unit size and delivering one unit of flow rate with one unit of head. In simpler terms, suction specific speed provides a measure of the pump's susceptibility to cavitation and indicates its efficiency and stability under varying operating conditions.
Calculating Suction Specific Speed
To calculate the Suction Specific Speed of a centrifugal pump, you can use a pump specific speed calculator. This tool takes into account the pump's flow rate, head, and rotational speed to determine the NSS value. By inputting the relevant parameters into the calculator, you can quickly assess the suction specific speed of the pump and make informed decisions regarding its suitability for a particular application.

For a pump with flow 1000 gpm, head 500 ft, speed3000 rpm and a maximum acceptable Suction Specific Speed 9000 - the Required Net Positive Suction Head
The flexible screw conveyor has a helicoid screw that rotates inside a fixed tube. Screw conveyors typically range in diameter from 2½ to 8 inches, and can be used for horizontal transports of up to 80 feet, and inclines of up to 60 degrees. An 8 inch diameter screw conveyor can transport 1,800 cubic feet/hour at 360 RPM at a 45 degree angle.
