Manufactured industrial centrifugal cantilever pumps comply with the international standard ISO2858-75 " centrifugal Pumps with axial inlet (nominal pressure 16.0 bar). Designation, nominal parameters and dimensions" in terms of the design and parameters of cantilever pumps.
Cantilever pumps are available in two versions:

• for water up to 80oC (with oil seal)
• for water up to 105oC (with mechanical seal).

The allowable pressure at the pump inlet is 3.5 kgf/cm2 (can be used as a boost).
The flow part is made of grey cast iron.
The pumps are manufactured with a supply from 3 to 480 m3 / h and a head from 3.5 to 125 m. they are designed for pumping water in stationary conditions, except for sea water with a pH of 6-9, containing various mechanical impurities of no more than 0.10% by volume and a particle size of no more than 0.21 mm.
The K-type pump is designed for operation in stationary conditions.

Cantilever centrifugal pumps for hot and cold water are produced with various options for turning the impeller (a, b, C).
The direction of rotation is clockwise when viewed from the electric drive.
The design of the pumps provides holes for removing water leaks through the stuffing box (mechanical) seal.Example of a pump unit symbol:
