FUNCTION
Centrifugal multistage vertical pumps of Boosta type are intended for pumping pure water without content of abrasive inclusions, solid particles and fibrous admixtures, as well as moderate aggressive liquids, demineralized water, mixtures of water and glycol and other liquid media at a temperature ranging from -30°С up to + 120°С, which are similar in physicochemical properties and in level of impact onto the structural members of the pumps, made of chrome-nickel stainless steel.
Primary use of Boosta pumps – automated pressure boost plants which are intended for automatic boosting and maintaining the pressure within water-supply systems.


DESIGN
The said pumps are centrifugal, multistage, vertical machines having flanged connection with a drive which is essentially a standard asynchronous motor corresponding to CENELEC norms.
All metal parts which come in contact with pumped liquid are made of stainless steel 08Х18Н10 or 08Х17Н13М2 according to the pump version.

Pumps of Boosta type are not designed to handle explosion-hazard fluids.


APPLICATION
Industrial, municipal and rural water-delivery
Irrigation systems and water application in agriculture
Water treatment facilities
Delivery of feed water to the boilers
Fire fighting systems
Plans for pressure boost (booster pumping plant)

DESIGN FEATURES AND BENEFITS
Suction and delivery branch pipes are of equal diameter and are positioned "in-line".
Stationary base members and impellers are made of chrome-nickel stainless steel.
Low axial thrusts allow the use of standard size series of electric motors of general industrial purpose.
The pump is furnished with end sealing of the shaft that does not require technical maintenance and do admits the replacement of the seal without dismantling the driving electric motor.
