New DB5.5 plastic magnetic-drive sealless centrifugal pump
Michael Smith Engineers is introducing the Finish Thompson DB5.5 Plastic Magnetic-Drive Sealless Centrifugal pump. This new model of DB pump covers flow rates up to 5m3/hr and differential heads to 6.5m; it is designed and built to provide the important benefits of sealless, magnetic-drive pumping, such as optimum efficiency and reliability, even in corrosive and challenging environments.
Finish Thompson DB5.5 pumps can be specified in a choice of polypropylene or PVDF and have extended dry-running capability. Moreover, when specified with a carbon bushing, DB pumps can be dry-run for hours, making them less prone to operator error or system upsets.
DB pumps offer high working pressure capability (up to 90psi), which means fluids with a high specific gravity (over 1.8) can be easily pumped without the need for impeller trimming. They have a maximum operating temperature of 82degC (180degF) for the polypropylene model and 104degC (220degF) for the PVDF option
High operating efficiency and lower energy costs are key objectives for all pump operators and DB pumps make an important contribution with operating efficiencies up to 70 per cent. For example, DB pumps with electric motors use significantly less energy while performing the same work as an equivalent air-operated pump.
The DB5.5 plastic magnetic-drive sealless centrifugal pump is available in a close-coupled design configuration for optimum magnet alignment. Each pump features evenly-spaced impeller trims that enable duty points to be met precisely. Furthermore, a two-piece impeller design enables the impeller or inner drive magnet to be replaced individually without having to replace the inner drive.
As a result of the non-metallic materials used for all the key wetted components, these pumps are suitable for handling corrosive liquids in chemical manufacturing, metal plating, surface treatment, wastewater treatment, electronics manufacture or other hazardous liquids that need to be transferred safely and efficiently. Finally, the pump is designed for either horizontal or vertical installation (vertical when equipped with an IEC motor).
