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
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 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.
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:
●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
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
●Air Conditioning System
