Morris
Pumps covers the complete range of low and head requirements encountered
in the wastewater industry. Shown below are the three (3) distinct hydraulic
designs that provide the highest practical pump speed for a given head
in combination with low pump NPSH requirements. This job-matched approach
maximizes operation and performance efficiencies while minimizing the
physical size of the pump and the power requirements of the pump driver.
As operating conditions are identified by the specifier, Morris pays close
attention in the selection of a pump with the highest specific speed.
Specific speed is a correlation of pump capacity, head and speed at the
best efficiency point (BEP) and is indicative of the shape, hydraulic
geometry and characteristics of an impeller and casing. These design considerations
are useful to the pump system designer to predict pump suction requirements
and to verify pump and station intake design limitations. |
