The peripheral flow pump is a type of centrifugal pump which is used to transfer large amounts of energy

The peripheral flow pump is a type of centrifugal pump which is used to transfer large amounts of energy. It is also very effective in a number of applications. These include water pressure boosting, jetting (high pressure cleaning), and filtration of liquids. In addition to these uses, the peripheral flow pump is also useful in water desalination plants.

A rotary impeller is the core component of a peripheral pump. This impeller is composed of a number of small radial blades, which align along the periphery. The blades may be configured to meet the specific performance requirements of a particular application. One such example is the stepped peripheral flow pump stage. This stage has an inner diameter that gradually decreases from inlet to outlet. By decreasing the internal diameter of the stage, the energy transfer from the impeller to the casing can be increased.

Another peripheral flow pump stage is the spiral grooved pump stage. It is structured by the upper end of the rotor 1. An inlet port 59B is provided at the lower end of the rotor, which allows gas molecules to enter the peripheral flow passage. Afterwards, the gas is sequentially compressed through the spiral grooved pump stage. As it passes through the peripheral flow passage, the discharged gas decelerates.

A curved impeller is another type of peripheral flow pump. This impeller is surrounded by a number of radial vanes that are arranged in a spiral manner. Each radial blade can be configured to meet the performance requirements of a pump.

The ring-shaped projection is provided in the inner surface of the rotor as a balance weight correction portion. It allows for a more even distribution of weights and increases workability when balancing the pump.

Peripheral flow pumps have dual inputs, one being from the rotor and one being from the casing. These inputs are connected through a thread-like groove 33, which is positioned on the outer peripheral surface of the rotor's upper end. Alternatively, the rotor and stator may be formed as a single unit.

A motor is provided to drive the pump. The motor rotor is affixed to the rotor and is supported by a bearing and a base. An oil tank 66B is provided for storing lubricating oil. Similarly, a cooling passage 67B is provided to circulate coolant.

A peripheral flow pump has many advantages over a centrifugal pump. This type of pump is easy to maintain and simple to operate. However, it is possible for the impeller of a peripheral flow pump to become damaged. This can lead to decreased performance at seals 34c. Hence, it is important to consider the design features and specifications when deciding on a peripheral pump. Various pumps are available and each design has its own characteristic curve. When comparing different designs, the characteristic curve is important to determine the efficiency of a pump.

Moreover, the fluid speed of the casing channel is significantly lower than the fluid speed in the peripheral channel. This makes it possible to increase the energy transfer between the impeller and the casing by decreasing the flow rate.
