家用泵低NPSH泵 - 系列DB
Domestic Pump Low NPSH Pumps - Series DB

The DB is a close coupled pump with two centrifugal impellers back-to-back. Placement of the impellers balances the axial thrust and opposed discharges balance the radial thrust. The mechanical seal operates between the stages to prevent excessive wear.
