Multistage pumps CM3
Horizontal, axially split multistage pump with radial impellers. Between bearing version. Cantilever design with pump in shaft axis. Pump design is in accordance with API 610-BB3. Combination of bearings, sliding pan for radial reaction and compensating rolling bearing for capturing residual axial force, lubricated with oil bath. The position of the impellers on the rotor assembly reduces the resulting axial force to a minimum. Seal chamber is designed for the installation of mechanical cassette seals according to API 682. Bearing bracket is equipped with ribs for intensifying heat transfer.
API 610/ISO 13709, EU directive ATEX 2014/34/EU
Technical specfications
Q max = 1680 m3/h
H max = 1000 m
T max = 200 °C
Application
Pumps are used in demanding chemical and petrochemical plants and power plants. It is a typical pump found in systems for supplying and transporting petroleum products and in cracking systems. Used in power blocks as power pumps and as injection pumps for oil fields. Designed for high pressure systems, maximum transport height (head) up to 800 m. Suitable for media with temperatures up to 250 °C.

Technical specfications
Q max = 1250 m3/h
H max = 500 m
T max = 200 °C
Application
Pump are used in chemical and petrochemical plants, power plants, as well as for transporting water and contaminated water. They are part of the installations in closed tanks or open sumps. Widely used in cracking systems, for pumping of the process residues and waste products. Used for pumping aggressive media.
Modification
External flushing / lubrication of guide sleeves
Heated structure
Multistage pumps CM5
Horizontal, radially split segmental pump with radial impellers, barrel type formation. Between bearing version. Cantilever design with pump in the shaft axis. Pump design in accordance with API 610-BB5. Combination of bearings, sliding pan for radial reaction and compensating rolling bearing for capturing residual axial force, lubricated in with oil bath. Pumps of smaller power parameters only fitted with rolling bearings. The axial force on the bearing is reduced by the balance disk behind the last degree. Seal chamber designed for the installation of mechanical cassette seals according to API 682. Bearing bracket equipped with ribs for intensifying heat transfer.
