▼Product introduction

The GD type inline pump features a vertical structure, allowing direct installation within water supply pipelines and saving space. It boasts a compact design, reliable sealing, and easy maintenance. Widely used in HVAC hot and cold water circulation, urban building water supply and drainage, and fire protection pipeline pressurization, it offers stable and efficient operation.

▼Application environment

Suitable for industrial and urban water supply and drainage, building pressurization, garden sprinkler irrigation, hot and cold water circulation pressurization and equipment matching.

▼Product features and advantages

1. Compact structure and easy installation: The pump and motor are coaxial, resulting in a small size that can be directly installed in pipelines, saving space and installation costs.

2. Axial inlet and excellent efficiency: Utilizing an advanced hydraulic model and axial suction structure, the flow path is smooth, hydraulic losses are minimal, and operation is highly efficient and energy-saving.

3. Smooth operation and extremely low noise: Employing a standard motor, a well-designed pump shaft, and a dynamically balanced impeller, the operating environment is more comfortable.

4. Reliable sealing and durable: Standard configuration includes a high-quality mechanical seal, effectively preventing leakage, wear-resistant and corrosion-resistant, with a long service life, reducing maintenance frequency and costs.

▼Working principle

CDL stainless steel multistage pumps operate on the centrifugal principle. A motor drives the pump shaft, which in turn drives a series of impellers to rotate at high speed. As the liquid passes through each impeller and guide vane, its kinetic energy is converted into pressure energy, resulting in a higher outlet pressure and enabling medium-to-high pressure liquid transport.

▼Shopping and maintenance suggestions

1. Matching Operating Conditions: Select the appropriate model based on flow rate and head requirements. Also, consider the characteristics of the medium (e.g., corrosiveness) when choosing the pump body material (cast iron/stainless steel, etc.), prioritizing reputable brands to ensure quality.

2. Routine Maintenance: Regularly check the shaft seal tightness, clean debris from the impeller, and add bearing grease approximately every 2000 hours of operation. During routine inspections, pay attention to any abnormal noises or vibrations.

3. Regular Overhaul: Conduct a complete disassembly at least once a year to check bearing wear and impeller cavitation. Replace seals and worn parts promptly to ensure the pump is leak-free and operates efficiently.

▼Precautions for use

1. Before startup: Ensure the pump is full of liquid before starting. Check the opening and closing status of the inlet and outlet valves, their sealing performance, and the lubrication of the bearings. Dry running is strictly prohibited.

2. During operation: Closely monitor the pump's pressure, current, and other parameters. Pay attention to any abnormal noises or vibrations. If overload, leakage, or other abnormalities occur, immediately stop the pump and investigate.

3. After shutdown: For long-term inactivity, drain the liquid from the pump, perform rust prevention treatment on the pump body, and manually rotate the pump periodically to prevent parts from seizing up.
