I. Product Overview:
The DL(DLR) vertical multistage centrifugal pump utilizes the hydraulic model of the IS type pump, a highly efficient and energy-saving product recommended by the state, featuring a vertical multistage, multi-section structure. The screw clamp securely joins the inlet section, middle section, and outlet section together. Each stage of the pump is equipped with one impeller and one guide vane. The axial force is resolved by the hydraulic balancing method, with the residual axial force borne by the ball bearing, lubricated with grease. The shaft seal is made of soft packing or mechanical seal. The product complies with the standard JB/T2727-93 "Vertical Multistage Centrifugal Pumps - Types and Basic Parameters," mainly supplied for lifting and conveying diluted, clean, non-corrosive, non-explosive water and liquids with similar physical and chemical properties to water, free of solid particles or fibers.
II. Product Application:
DL (DLR) vertical multi-stage centrifugal pumps are widely used in high-rise building fire protection, domestic water supply, and air conditioning unit circulation and cooling water transport.
III. Product Features:
DL (DLR) Vertical Multistage Centrifugal Pump: Advanced hydraulic model; high efficiency, wide performance range.
2. DL (DLR) Vertical Multistage Centrifugal Pump: Innovative design, reliable operation: Eliminates the balancing drum, utilizes hydraulic balance for its axial force, which completely resolves issues like easy rusting, seizing, and wear of the balancing drum, ensuring more reliable operation.
3. DL (DLR) Vertical Multistage Centrifugal Pump: Reduced Operating and Maintenance Costs - Equipped with high-quality mechanical seals, it is wear-resistant, leak-proof, with a long service life and low failure rate, resulting in lower operating and maintenance costs.
4. DL (DLR) Vertical Multistage Centrifugal Pump: Smooth operation, low noise; equipped with a low-speed motor for even smoother pump performance and reduced noise.
5. DL (DLR) Vertical Multistage Centrifugal Pump: Vertical design, compact footprint.
