Finish Thompson DB Series Magnetic Drive Pump

Back

The DB series magnetic drive pumps are designed for high hydraulic efficiency and corrosive fluid handling. The high efficiencies of the DB series lower energy consumption and operating costs over the long life cycle of the pumps. Constructed from Polypropylene or PVDF, the DB series operate durably in the most corrosive of environments and can even run dry without damage. Using powerful neodymium magnetic technology, the DB sealless mag drive pumps are an ideal replacement for mechanical sealed pumps in corrosive duty applications Download Brochures>

Gas Engine Option for DB/SP Series Magnetic Drive Pumps

Finish Thompson has developed a gasoline engine option for the DB and SP Series magnetic drive centrifugal pumps. The option is ideal for applications where an electrical supply is not available. Click Here to Download Brochure>

Easy Set Outer Drive
Measurement-free outer drive ensures optimum magnet alignment and easy motor installation. Allows optional vertical operation when used with IEC motors

Multiple Impeller Diameters
Allows hydraulic requirements to be precisely met. Two piece impeller design allows impeller to be changed without having to replace inner drive

Multiple Connections
NPT or BSP threads, raised face adjustable flanges or union

Run Dry System
The DB can run dry without damage when equipped with a chemical grade carbon bushing in optimum operating conditions. This helps protect the pump from operator errors and system upsets
