CYZ Series Self-Priming Centrifugal Pump

CYZ Series Self-Priming Centrifugal Pump

The CYZ Series Self-Priming Centrifugal Pump is a high-efficiency single-stage centrifugal pump specially designed for the fast transfer of petroleum products and light chemical liquids. It features an excellent self-priming capability, stable performance, and simple operation, making it widely used in oil depots, petrochemical plants, fuel transportation systems, ports, and industrial liquid transfer applications.

This series is particularly suitable for handling gasoline, diesel, kerosene, aviation fuel, and other light oil media. The pump is designed with a gas-liquid separation structure, allowing it to achieve rapid self-priming without the need for bottom valves or external priming devices, significantly improving operational efficiency.

Product Features

Strong Self-Priming Performance
The CYZ Series pump can quickly evacuate air from the suction line and achieve fast self-priming, eliminating the need for additional priming equipment.

Suitable for Petroleum Products
Specially designed for transporting gasoline, diesel, kerosene, and other light fuel oils with excellent compatibility and stable performance.

Stable and Reliable Operation
Smooth hydraulic design ensures stable flow output, low vibration, and safe continuous operation.

High Efficiency and Energy Saving
Optimized impeller and flow channel design improve hydraulic efficiency and reduce energy consumption.

Simple Structure and Easy Maintenance
Compact structure allows easy installation, disassembly, and maintenance, reducing downtime and operating costs.

Safe and Durable Design
High-quality materials and sealing systems ensure safe operation in flammable and explosive environments when equipped with explosion-proof motors.

Working Principle

The CYZ Series Self-Priming Centrifugal Pump operates based on centrifugal force combined with a gas-liquid separation chamber. During startup, the pump automatically separates air and liquid in the pump casing. The impeller rotation creates negative pressure, enabling rapid suction of liquid into the pump. Once fully primed, the pump operates as a standard centrifugal pump with continuous and stable discharge.

Main Applications

The CYZ Series Self-Priming Centrifugal Pump is widely used in:

• Oil depots and fuel storage systems

• Petrochemical transportation systems

• Tank truck loading and unloading

• Port fuel transfer systems

• Industrial light oil circulation

• Emergency drainage and liquid transfer

• Chemical liquid transportation

Suitable Media

The pump is suitable for transporting:

• Gasoline

• Diesel oil

• Kerosene

• Aviation fuel

• Light fuel oil

• Other petroleum-based low-viscosity liquids

• Some non-corrosive chemical liquids

Product Advantages

Compared with conventional centrifugal pumps, the CYZ Series Self-Priming Centrifugal Pump eliminates the need for a bottom valve and separate priming system, offering faster startup, simpler pipeline design, and higher operational efficiency. It is especially suitable for mobile or fixed fuel transfer systems requiring frequent start-stop operation.
