**Product Description**
The DL series Vertical Multistage Pump, also known as a Jockey Pump for fire fighting, is a single-suction, vertical segmental centrifugal pump. It is widely used in fire protection systems to boost water pressure. This pump is designed for transferring clear water or liquids with similar physical and chemical properties to water, typically at temperatures below 80°C. The DLR series is suitable for higher temperature applications, up to 120°C.
**Performance Range:**
- **Capacity (Q):** 20–200 GPM
- **Head (H):** 21–217 meters
The pump features a compact design, low noise operation, and efficient space utilization. Its axial forces are balanced using a balancing drum, ensuring smooth and stable performance. The pump can be equipped with either a packing seal or mechanical seal depending on the application requirements.
**Material Configuration:**
The flow passage components of the pump can be customized based on the type of liquid being handled. Here is a general recommendation for material selection:
| Item | Clean Water | Drinking Water | Sewage Water | Hot Water | Sea Water |
|--------------------|-------------------|--------------------|-------------------|-------------------|--------------------|
| Case & Cover | Gray Iron (HT250) | S.S. 304 | Ductile Iron (QT500) | Cast Steel | Duplex S.S. 2205 |
| Impeller | Gray Iron (HT250) | S.S. 304 | Ductile Iron (QT500) | 2Cr13 | Duplex S.S. 2205 |
| Wearing Ring | Gray Iron (HT250) | S.S. 304 | Ductile Iron (QT500) | 2Cr13 | Duplex S.S. 2205 |
| Shaft & Sleeve | C.S. 45 | S.S. 420 | 40Cr | 40Cr | Duplex S.S. 2205 |
| Column Pipe | C.S. Q235 | C.S. Q235 | C.S. Q235 | C.S. Q235 | Duplex S.S. 2205 |
*Note: Detailed material specifications may vary depending on the specific liquid and site conditions.*
**Model Explanation:**
For example, the model "65DL16X5" breaks down as follows:
- **65:** Inlet diameter (in mm)
- **DL:** Series name for Vertical Multistage Pump
- **DLR:** Series for high-temperature applications
- **16:** Single-stage head (in meters)
- **5:** Number of stages (total head = 16 × 5 = 80 meters)
**Structure:**
The DL series pumps are vertically mounted with the inlet located at the top and the outlet at the bottom, both in a horizontal direction. The number of stages can be adjusted according to the required head. The outlet can be rotated 90°, 180°, or 270° to accommodate different installation needs. The pump is ideal for use in fire suppression systems, industrial water supply, and high-rise building water boosting.
**Additional Features:**
- Compact and space-saving design
- Low noise operation
- Flexible mounting options
- Suitable for various industries including residential, commercial, and industrial applications
Whether you need a reliable pump for fire protection or water boosting, the DL series offers a versatile and durable solution tailored to meet your specific needs. For custom configurations, please contact the manufacturer directly.
Mixing Machinery
Mixing machine is a mechanical equipment that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, the contact surface area of the material can also be increased to promote chemical reactions; It can also accelerate physical changes.
The commonly used mixers are divided into four categories: gas and low viscosity liquid mixers, medium to high viscosity liquid and paste mixers, and powder and granular solid material mixing machinery.
