Water Booster Centrifugal Fire Fighting Vertical Multistage Pump
1. High Pressure Stainless Steel Vertical Multistage Centrifugal Water Pump
QDL vertical multistage centrifugal pumps are designed for the transport of water and liquids with physical and chemical properties similar to water. The QDL type operates in temperatures from 0 ºC to 80 ºC, while the QDLR type handles 0 ºC to 130 ºC. Pump inlet pressure must not exceed 0.6MPa.
Designed for vertical installation, these pumps feature a compact structure, low noise, and a small footprint. They are primarily used in high-rise building water supply, central heating systems, fire systems, air conditioning, and various industrial water supply systems.
