Advantages and disadvantages of centrifugal pumps

Advantages:

Simple and compact structure, for the same conveying volume, centrifugal pump occupies a small area, light weight, less material consumption, no high requirements for the foundation of the pump, so the manufacturing and installation costs are less. It can run at high speed, and can take 2 or 4 poles motor direct connection, the transmission structure is simple and easy to install. Centrifugal pump without a valve, so suitable for transporting suspension, special design can also transport large solids in suspension available chemically resistant materials to manufacture the pump, suitable for transporting corrosive solutions. Because of the simple structure, less parts, less failure, durable, less maintenance costs, easy management, reliable work. The output volume can be adjusted by the discharge valve arbitrarily or even fully closed, so there is no danger of infinite rise of pressure head. For the amount of liquid to be transported is large. When the pressure head is not required to be large, the centrifugal pump is most suitable. The discharge is uniform without pulsation.

Disadvantages

Before operation, the pump body must be filled with liquid. Unsuitable for supplying small flow rate and large pressure head, low efficiency and limited. When encountering imperfect design or improper operation, such as milk, it is easy to produce foam and affect the production of the next process. Improper installation. The phenomenon of "air binding" will occur. Efficiency is also lower than reciprocating pumps. Please pay attention to the China pump industry network. Zibo Great Wall Pump Industry Co.
