Multistage Centrifugal Pump

Multistage centrifugal pump is a most popular type of centrifugal pumps, with two or more impellers; it can make higher pressure than single stage pump, widely used at various sites that request high pressure. According to different structure, it with two types, one are vertical multistage centrifugal pump and another horizontal multistage centrifugal pump.

What is a multistage pump?

Multistage centrifugal pump is a type of centrifugal pump that containing two or more impellers. General, the impellers connected in series and mounted on the same shaft, the outlet pressure increase along with the number of impellers. Compare to single stage pump, multistage centrifugal pump containing two or more impellers, but single stage pump only one single impeller, that’s why called multistage pump. And multistage centrifugal pump with higher pressure than single stage pump, so multistage pump is more suitable for some project that requests high pressure, like high building water supply.

The type of multistage centrifugal pump

Multistage centrifugal pump mainly have two type different structures. One is with a vertical shaft, and another is with a horizontal shaft.

Vertical multistage centrifugal pump – It is a type of inline pumps, with a vertical shaft, and mounted impellers.

Same with inline pump, vertical multistage centrifugal pump also great savings the floor space, it is a most important advantage for our water treatment project. Besides this, high pressure and wide range flow are also a great benefit of vertical multistage pump. So, it’s also called high pressure pump.

The Grundfos CR multistage centrifugal pumps are the most popular multistage pumps at globe world, with reliability, high efficiency and service-friendly advantages. But it’s with high price. Yaness also as a top pump manufacturer, which produce similar vertical multistage pump with same advantages and competitive price.

Yaness adopt laser welding impeller technology, it is a leading welding technology to ensure pump high efficient running, are most welcome to customers. Yaness’ vertical multistage centrifugal pump is a good substitute to the Grundfos CR.

The vertical multistage centrifugal pump has many advantages and is applied to in various situations, but it’s not suitable to pumping liquid with solids, its best applied in applications like these:

● Water Supply

● Pressure Boosting

● Liquid Transfer

● Water Treatment

● Lrrigation

● Cooling and Air Conditioning System (HVAC)

● Fire Fighting Systems (Jockey Pump)

Horizontal Multistage Centrifugal Pump – This type centrifugal pump contains a horizontal shaft mounted impellers.

Horizontal multistage centrifugal pump adopt maintenance-free mechanical seal, and all flow passage components are made of stainless steel 304L/316L, same as vertical multistage pump. Horizontal type pump also has benefit of low noise, light corrosion resistance, and long service life

, etc.

This type pump mainly used for liquid transfer of domestic central air-conditioning and industry. And it’s also no suitable to transfer liquid with solid particle or fiber (We recommend using sewage pump for sewage water), therefore, freshwater applications is good for this type pump:

● Industrial Cleaning

● Water Supply
