CDR Pumps refine already successful STN mag-drive ATEX pumps

Date Posted: 10/05/2010

The already successful STN series of magnetic drive pumps from CDR Pumps has undergone a series of design refinements to accommodate the ATEX certification requirements.

Modifications include use of a heavy duty Cast Iron lantern and alloy feet to accommodate the heavier ATEX motors making the pumps far more robust.

The ATEX pump comprises a Carbon filled ETFE casing for static energy earthing, while maintaining optimum corrosion resistance to the most arduous of chemicals.  The bearing systems as standard is Glass loaded PTFE running against a stationery ceramic shaft and axial thrust shoes, with the option of upgrading to Silicon Carbide for solids handling.  The nozzle connections allow for unions to be used directly onto the pump for easy disconnection, or alternatively flanged fittings to either ANSI 150 RF or BS4504 PN16 specification.

Motor powers range from 0.75kw to 4kw to cover the complete hydraulic characteristics of the pumps with a single size mag drive coupling.

The ATEX version complements the standard STN series, being manufactured for more than 8 years in standard Polypropylene and ETFE materials, and have been used widely in the chemical distribution industry, CIP applications, OEM installations as well as small scale chemical plants and transfer duties.
