Share a great achievement that Grundfos CR255----the world`s biggest vertical multistage pump is made in Bjerringbro, Denmark!
Below some impressive facts:
Rated flow: 330CBM/H (93l/s).Head:250m -about thirteen times the length of a bowling lane!
Power:300hp /220kw
Weight:up to 1.5 tons, more than the weight of a small car !
The pump is used for water supply in waterworks and for water treatment.
Now days, in the market, mostly supplier`s max flow rate at 200-240CBM and max head around 300 meters. Vertical multistage pumps in this range can also meet the needs of most markets. In the past, the demand above this range was generally solved by multiple vertical multistage pumps in series (to superimpose the head) or in parallel (superimpose the flow). However, the successful interview at CR255 makes it possible for some large projects requiring large flow and high head to be completed with a single multistage pump.
