Plastic pumps handle corrosive environments
A
Michael Smith Engineers product story
Edited by the Engineeringtalk editorial team
Jan 25, 2008
The DB series pumps offer high working pressure capability which means fluids with a high specific gravity can be easily pumped without the need for impeller trimming.
Michael Smith Engineers has released plastic magnet-drive centrifugal pumps which are designed for use in the most corrosive and challenging environments.
The Finnish Thompson DB series of leak-free pumps include eight models available in a choice of either polypropylene or PVDF and provide flows up to 27m3/h and heads up to 27m.
As a result of the nonmetallic materials used for both the housing and all the key wetted components, they are suitable for pumping corrosive liquids in chemical manufacturing, metal plating, surface treatment, wastewater treatment, electronics manufacturing or wherever hazardous liquids need to be transferred safely and efficiently.
They are available in a close-coupled design configuration for optimum magnet alignment and provide an extended dry running capability when specified with a carbon bushing and are therefore protected from system upsets.
High operating efficiency results in lower energy consumption, and improved hydraulic coverage for both 50 and 60Hz operation, with evenly spaced impeller trims enabling duty points to be precisely met.
A two-piece impeller design allows the impeller or inner drive magnet to be individually replaced.
The DB series pumps offer high working pressure capability which means fluids with a high specific gravity can be easily pumped without the need for impeller trimming.
The pumps are designed for either horizontal or vertical installation.
They have a maximum operating temperature of 82C for the polypropylene model and 104C for the PVDF option.
