The DL and DLR series of vertical multistage centrifugal pumps (operating at a low speed of n = 1450 r/min) are high-efficiency products developed by our company to meet the specific demands of the high-rise building water supply market, in compliance with the national standard GB6245-2006, "Fire-fighting Pumps." These pumps are designed for transporting media that are free of hard particles and possess physical and chemical properties similar to those of water. They offer a flow rate range of 5–400 m³/h, a head range of 22–300 m, a power range of 1.5–250 kW, and a port diameter range of 40–200 mm. Each pump unit can be configured with one to five discharge outlets.
