Nfpa Certified Multistage Diesel Engine Fire Pump System

The multistage pump parts are very similar to those of the standard Centrifugal pump except for the Multistage Centrifugal pump where the additional parts are diffusers which efficiently channel the fluid into the eye of the impeller or to the following stage. In the side channel pump, there are intermediate plates with the scalloped side channel and liquid parts. In multistage centrifugal pumps, because of the high thrust that is generated due to the impellers facing in the same direction, ther

A multistage pump operates by one impeller feeding into the next impeller and the number of impellers required depend on the discharge pressure requirement. Liquid enters the pump and then passes through the various number of impellers in a sequence from the left to right.

The applications for multi stage pumps are many and varied and can be used for delivering water to high rise buildings, reverse osmosis (RO), boiler feed water, spraying, high pressure cleaning, water works, heating, condensate, fuel delivery, oil and gas production, power generation & mining and other high pressure and temperature applications..

Types of multistage pumps include; Horizontal Multistage Centrifugal pump (above ground) Vertical Multistage Centrifugal pump (above ground) Submersible/Sump pump types Side Channel pump Combination pumps i.e Centrifugal low NPSH first stage with side channel additional stage. Horizontal split case pump Vertical Turbine pump Sanitary Multistage pump

If we were to compare the Centrifugal multi stage pump to a high pressure duty pump - the Centrifugal multi stage pump even though it is more complex and costly, it would probably be a better hydraulic fit, have a better efficiency and be more reliable. With its hydraulic modules, the ability to supply additional impellers and its ability to trim those impellers, the duty point can me met exactly without compromise. The selection is more likely to be close to 'BEP' and will run efficiently and r
