Single stage centrifugal pumps are the most common pump for fluid transfer in high flow rate, low pressure installations. If a lower flow rate or a higher pressure is needed over what a single stage centrifugal pump can provide, a multistage centrifugal pump is a better suited alternative. Centrifugal water pumps are common single stage pumps, however due to the wide range of materials[PDF]
Experiment (9): Centrifugal pump Introduction: and where a single operating capacity or a narrow range of capacities is required. The general design is usually simple with few mechanical parts to fail, however, and it is possible to operate a centrifugal pump outside ideal parameters to 40°C), but it is sufficient for many practical文件大小: 1MB
When centrifugal pumps are connected in a line, head increases from one pump to the next, increasing fluid pressure as well. A multi-stage pump, like a vertical turbine, does essentially the same thing. When two of the same pumps are in series, the combined performance curve will have double the head of a single pump for the given flow rate.

A centrifugal pump combines the hydraulic design of an end-suction pump with a submersible motor. Submersible pumps are always of the close-coupled type meaning that the impeller mounts directly on the end of the motor shaft, and the pump casing attaches directly to the motor frame.[PDF]
of complementary pump types, from pre-engineered process pumps, to highly engineered and special purpose pumps and systems. Pumps are built to recognized global standards and customer specifications. Pump designs include: • Single-stage process • Between bearing single-stage • Between bearing multistage • Vertical • Submersible motor
Practical Centrifugal Pumps is a comprehensive guide to pump construction, application, operation, maintenance and management issues. Coverage includes pump classifications, types and criteria for selection, as well as practical information on the use of pumps,
The single-stage centrifugal pump, consisting of one impeller, is the most widely used in production operations. They are used in pumping services of low-to-moderate TDHs. The TDH (total dynamic head) is a function of the impeller’s top speed, normally not higher than 700 ft/min. Single-stage pumps can be either single or double suction.
