The DB4 centrifugal pump.

The DB3, 4, 5 seal-less pumps from Finish Thompson have the lowest flow performance available from the DB Series and have extended run dry ability (with carbon bushing), high operating efficiency, and working pressures to 60 psi.

The pumps use neodymium magnets and are constructed of either polypropylene or PVDF for corrosion resistance. They can provide up to 19 gpm or nearly 35 feet of head. The pumps are available with IEC 56/B14 or IEC 63 /B14 motor frames and a choice of 1/8 or ¼ Hp TEFC motors.
