CENTRIFUGAL PUMP BENEFITS

Light weight
Ease of maintenance
Increased wear resistance of the pump parts:
Volute, Nozzle, Impeller, Disks
Steel casting of all parts
The impeller is made of steel 20H13L

: Universal, modular design that allows the Customer to purchase only those parts that are necessary for repair

: The possibility of changing the direction of rotation due to a simple installation of the impeller, respective rotation direction and scroll turning (only the impeller changes, the remaining parts remain the same).

Compactability
Extreme strength
Requires minimal installation space
Horizontal or vertical arrangement

CENTRIFUGAL PUMP ADITIONAL OPTIONS

Right or left version: Due to the universal design, the centrifugal pump can be shipped in both left and right versions without loss in power.

Flushing holes: Flushing holes with cap screws allow for cleaning the volute when working with cement slurry

Increased impeller hardness: Increased impeller hardness up to 65-69 HRC extends the pump service life.

Elastic coupling: It is possible to produce the coupling joint tooled for any electric motor

Various positioning rams: The variety of positioning rams allows for using the centrifugal pump more effectively, and also decreasing the assembling place

Back-flow valve for self-feeding: The valve provides continuous occupancy of the pump with process liquid to increase the suction head

Electrical, diesel, hydraulic drive: Centrifugal pump works effectively with all appropriate drives, which makes it universally useful

Key or splined connection to the shaft: Production of shaft ends in two versions: with protruding end - key connection, with short end - inner splines
