Product Overview
The DL/DLR vertical multistage low-speed clean-water pump (n = 1450 r/min) is designed to meet practical water-supply requirements in high-rise buildings and complies with GB 6245-2006 — Performance Requirements and Test Methods for Fire Pumps.
It is used for conveying clean water or water-like liquids with similar physical and chemical properties, free of hard particles.
Performance range: Flow 5–360 m³/h, head 22–300 m, power 1.5–220 kW, nozzle diameter φ40–φ200 mm.
A single pump can be configured with 1 to 5 discharge ports.
Model Designation
Key Features
-
Low-speed (1450 r/min) vertical multistage configuration for building water supply and fire water supply duties.
-
Rigid direct coupling between pump and motor; no on-site alignment is required during installation.
-
Vertical design reduces footprint and simplifies installation and maintenance.
-
Replaceable wear rings and balance sleeves for wear management.
-
Shaft sealing can be configured as packing seal or mechanical seal as required.
-
One pump supports 1 to 5 discharge ports for flexible multi-point distribution.
Engineering Summary
This series adopts a low-speed (1450 r/min) vertical multistage design, optimized for domestic water supply, constant-pressure fire water supply, automatic sprinkler systems, and water curtain systems in high-rise buildings.
It is also applicable to industrial and mining drainage, long-distance water transfer, packaged water-supply units, and general process-water services.
Maximum medium temperature:
-
DL type: ≤ 80°C
-
DLR type: ≤ 120°C
Typical Applications
-
Domestic water supply in high-rise buildings
-
Fire-fighting normal pressure systems
-
Automatic sprinkler systems
-
Water curtain systems
-
Industrial and mining drainage
-
Long-distance water transfer
-
Packaged water-supply units and process-water services
Rotation direction: Viewed from the drive end, the DL pump rotates counterclockwise.
System Configuration
The pump unit consists of the motor and pump assembly. The motor is a Y-series three-phase asynchronous motor.
The pump and motor are rigidly coupled, and no alignment is required during installation.
The vertical construction reduces installation footprint and simplifies service access. Replaceable wear rings and balance sleeves are provided for wear control. The interfaces of the suction and discharge sections are sealed by gaskets and bolted joints. The shaft seal may be configured as packing seal or mechanical seal according to user requirements.
Components & Supply Scope
-
Stationary components: Suction section, intermediate sections, diffuser section, and discharge outlet, fitted with replaceable wear rings and balance sleeves.
-
Rotating components: Shaft, impellers, and balance drum.
-
Bearing support: Lower end supported by water-lubricated bearing; upper end supported by angular contact ball bearing.
-
Axial force balance: Mainly absorbed by the balance drum; residual axial force is carried by the angular contact bearing.
-
Sealing system: Joint sealing; shaft seal can be packing seal or mechanical seal.
Technical Service
Shaft seal type (packing or mechanical seal) can be configured according to user requirements. For installations above 1000 m elevation and for different medium temperature limits (DL/DLR), operating conditions should be specified at ordering to ensure proper configuration.
Operating Conditions
-
Pumped medium shall be water-like, kinematic viscosity ≤ 150 mm²/s, free from solid particles and non-corrosive.
-
Installation altitude ≤ 1000 m; for higher altitudes, this must be specified at ordering for configuration optimization.
-
Medium temperature range: –15°C to 120°C
-
DL type: ≤ 80°C
-
DLR type: ≤ 120°C
-
-
Maximum system working pressure: ≤ 2.5 MPa
-
Ambient temperature ≤ 40°C, relative humidity ≤ 95%
Service Conditions
Suitable for clean water or similar liquids. The medium shall be free of solid particles, non-corrosive, and within the specified viscosity and temperature limits. For altitude above 1000 m or higher-temperature duties, operating conditions must be specified at ordering for proper configuration matching.
Protection Functions
Axial thrust is balanced primarily by the balance drum, with residual axial load carried by the angular contact bearing. The bearing arrangement (lower water-lubricated bearing and upper angular contact ball bearing) supports stable rotor operation and reduces operational risk.
Selection Criteria
-
Select flow, head, power, and nozzle diameter according to system requirements (5–360 m³/h, 22–300 m, 1.5–220 kW, φ40–φ200 mm).
-
For fire-fighting projects, selection shall comply with GB 6245-2006 requirements.
-
Determine the number of discharge ports (1 to 5) based on distribution demands.
-
Select type according to medium temperature: DL (≤80°C) or DLR (≤120°C).
-
Verify maximum system pressure (≤2.5 MPa) and installation altitude (≤1000 m; >1000 m must be specified).
