Model Description
Product Overview & Applications
The DL vertical multistage clean water pump (low-speed type, n = 1450 r/min) is a newly developed product designed according to the actual needs of high-rise building water supply systems and in full compliance with the national fire protection standard GB6245-2006 “Fire Pump Performance Requirements and Test Methods.”
It is suitable for conveying non-corrosive liquids without hard particles and with physical and chemical properties similar to clean water.
Flow range: 5–360 m³/h
Head range: 22–300 m
Motor power: 1.5–220 kW
Inlet/outlet diameter: φ40–φ200 mm
Each pump can be configured with 1–5 outlet ports.
The DL vertical multistage clean water pump is mainly used for domestic water supply in high-rise buildings, fire-fighting constant-pressure systems, automatic sprinkler systems, and water curtain supply. It can also be used for industrial and mining water supply and drainage, long-distance water transfer, equipment supporting, and various process water applications.
The medium temperature for DL pumps should not exceed 80°C, and for DLR models not exceed 120°C.
Product Features
The DL vertical multistage clean water pump adopts advanced hydraulic models, providing high efficiency, smooth performance curves, and a wide operating range. It meets the requirements of the Fire Protection Bureau and supports diverse user needs.
The pump features a vertical segmented structure with stable operation, low noise, long service life, small footprint, and convenient installation and maintenance.
Operating Conditions
Operating Conditions
1. The pumped liquid should be similar to clean water, with kinematic viscosity <150 mm²/s, free of hard particles and corrosive properties.
2. Installation altitude <1000 m; for higher altitudes, 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 clean water pump consists of two major components: the motor and the pump.
The motor is a Y-series three-phase asynchronous motor, connected to the pump through a rigid coupling, eliminating alignment during installation.
The pump is composed of a stator assembly and a rotor assembly.
The stator assembly includes the suction casing, middle casing, diffuser, discharge casing, and stuffing box. To prevent wear, seal rings and balance bushings are installed on the stator and can be replaced after wear.
The rotor assembly consists of the shaft, impellers, and balance drum. The lower rotor end uses a water-lubricated bearing, and the upper end uses an angular contact ball bearing. Most axial force is balanced by the balance drum, while residual force is carried by the angular contact ball bearing.
The joint surfaces of the suction and discharge casings are sealed with paper gaskets. Shaft sealing can be packing seal or mechanical seal according to user requirements.
The pump rotates counterclockwise when viewed from the motor drive end downward.
Main advantages:
1. Compact structure, small size, elegant appearance, small installation footprint, reducing construction costs.
2. Suction and discharge ports are located on the same centerline, simplifying pipeline layout.
3. According to actual needs, inlet/outlet directions can be arranged at 90°, 180°, or 270°.
4. The discharge port can be configured with 1–5 outlets to achieve different heads from a single pump.
