Product Description
Model Code Explanation
Product Introduction
DL Vertical Multistage Low-Speed Clean Water Pump (low speed n=1450 r/min) is a newly developed product based on actual high-rise building water supply requirements and in accordance with the national fire protection standard GB6245-2006 “Fire Pump Performance Requirements and Test Methods.”
It is suitable for conveying media that are free of hard particles and similar to clean water in physical and chemical properties.
The flow range is 5–360 m³/h, head range is 22–300 m, power range is 1.5–220 kW, and diameter range is φ40–φ200 mm.
A single pump outlet can be configured with 1–5 discharge ports.
Product Features
DL Vertical Multistage Low-Speed Clean Water Pump adopts an advanced hydraulic model, featuring high efficiency, smooth performance curves and a wide operating range. It meets the relevant requirements of the Fire Protection Bureau and satisfies various user demands.
The DL pump adopts a vertical sectional structure, offering stable operation, low noise, long service life, small footprint, and convenient installation and maintenance.
Product Applications
DL Vertical Multistage Low-Speed Clean Water Pump is mainly used for domestic water supply in high-rise buildings, fire-fighting constant-pressure water supply, automatic sprinkler systems, and automatic water curtain systems.
It can also be applied in industrial and mining drainage, long-distance water transfer, equipment supporting water supply, process water supply and other applications.
The medium temperature for DL pumps should not exceed 80°C; for DLR type, the medium temperature should not exceed 120°C.
Operating Conditions
1. The pumped medium should be similar to water, with a kinematic viscosity <150 mm²/s, free of solid particles and non-corrosive.
2. The installation altitude for the DL pump should be <1000 m. If exceeded, please specify when ordering so we can provide a more reliable configuration.
3. Medium temperature: -15°C to 120°C.
4. System working pressure ≤ 2.5 MPa.
5. Ambient temperature ≤ 40°C, relative humidity ≤ 95%.
Structure Description
The DL Vertical Multistage Low-Speed Clean Water Pump consists of the motor and the pump. The motor is a Y-series three-phase asynchronous motor. The pump and motor are connected by a coupling with a rigid connection, requiring no alignment during installation.
The pump consists of stationary and rotating components. The stationary components include the suction section, intermediate section, diffuser, discharge section, stuffing-box body and other parts. To prevent wear, the stator is equipped with wear rings and balance sleeves, which can be replaced when worn.
The rotating components include the shaft, impellers, and balance drum. The lower end of the rotor is supported by a water-lubricated bearing, and the upper end by an angular contact ball bearing. Most of the axial force is borne by the balance drum, with the remaining small residual axial force borne by the angular contact ball bearing.
The joint surfaces of the suction and discharge sections are sealed with gaskets through tightening bolts. The shaft seal may be packing seal or mechanical seal, depending on user requirements.
The rotation direction of the DL pump is counterclockwise when viewed from the drive end.
1. Compact structure, small size, attractive appearance, small footprint, reducing building cost.
2. The pump inlet and outlet are on the same centerline, simplifying pipeline installation.
3. According to installation requirements, the inlet and outlet can be assembled in 90°, 180°, or 270° orientations.
4. According to application needs, the pump outlet can be configured with 1–5 discharge ports to achieve different heads from the same pump.
