The model DB pump covers flow rates up to 5 m3/hr and differential heads to 6.5 m and is designed with improved efficiency and reliability even in corrosive and challenging environments.
 
The DB pump is now available from pumping specialists Michael Smith Engineers.
 
DB5.5 pumps can be specified in a choice of polypropylene or PVDF and have extended dry-running capability. When specified with a carbon bushing DB pumps can be dry-run for hours, making them less prone to operator error orsystem upset.
 
 DB pumps offer a working pressure capability of up to 90 psi, which means that fluids with a high specific gravity (over 1.8) can be pumped without the need for impeller trimming. They have a maximum operating temperature of 180ºF (82ºC) for the polypropylene model and 220ºF (104ºC) for the PVDF option. Operating efficiencies are up to 70% and DB pumps with electric motors use significantly less energy whilst accomplishing the same work as an equivalent air-operated pump.
 
The DB5.5 pump is available in a close-coupled design configuration and features evenly spaced impeller trims. A two-piece impeller design allows the impeller or inner rive magnet to be individually replaced without having to replace the innerdrive.                          
 
The pumps are suitable for handling corrosive liquids in chemical manufacturing, metal plating, surface treatment, wastewater treatment and electronics manufacture. They are designed for either horizontal or vertical installation (vertical when equipped with an IEC motor).
