TUSSU vertical multistage pump can 100%interchangeable with grundfos.The pump model we have are CR, CRI, CRN, CRE, CRIE, CRNE – Vertical multistage centrifugal pumps
Vertical multistage centrifugal pumps have multiple liquid chambers (or stages) that are connected in series. Fluid enters the first chamber at suction line pressure and leaves at some elevated pressure. Upon leaving the first stage, the fluid enters the second stage where the pressure is increased further.
The more stages the pump has, the higher the final discharge pressure. These pumps have the unique ability to produce higher and higher pressures with the addition of every stage, but flow range always remains constant for a given rpm.
There are a couple different types of multistage pumps. Those with a horizontal shaft, and those with a vertical shaft. vertical multistage pump is mainly used for irrigation and livestock water system, also for city, factory, railways, mining, water supply and drainage construction site.
