Standard Design: The multistage centrifugal pumps, specifically the CV 11 to CV 14 models, are designed with closed impellers suitable for medium and high heads. They feature a close-coupled design with impellers directly mounted on the motor shaft. The industrial construction includes a motor shroud and adjustable feet upon request. Wetted parts are made from CF-8M 1.4408 / AISI 316 stainless steel, which are investment cast and electro-chemically polished. These pumps can handle flow rates up to 40 m3/h and heads up to 140 meters (10 bar).

Seals: The pumps use mechanical seals with seats conforming to EN 12756 and ISO 3069 standards. They feature a single internal mechanical seal with elastomers certified to FDA standards, including EPDM, Fluorocarbon (Viton), Silicone, and P.T.F.E. (FEP).

Connections: The pumps are compatible with various international standards, including DIN, SMS, IDF, BS/RJT, DS, CLAMP, and EN 1092-1 PN16 flanges.

Applications: These pumps are suitable for industrial or foodstuff applications where 316 stainless steel is necessary, but without specific cleaning or sterility requirements. They are ideal for applications where hygiene is of low importance and are widely used in cleaning and washing systems, fluid filtration, general transfer, feeding, and water treatment. However, the closed impellers are not suitable for handling products containing solids or highly viscous liquids.

Performance and Dimensions: The document provides detailed performance data and dimensions for various models, including CV 11 to CV 18 and CV 51 to CV 83, at 2900 rpm. The performance data applies to water at 20°C and 1013 millibar, though it is noted as non-binding. Dimensions are provided for both horizontal and vertical executions, with specifications for power (kW), inlet and outlet diameters (DNa, DNm), and various other measurements.

General Notes: The document emphasizes that all instructions, data, and representations are indicative and non-binding. CSF Inox reserves the right to modify the data, drawings, and information without notice.
