CYZ Series Marine Self-priming Centrifugal Oil Pump

Marine CYZ Series Self-priming Centrifugal Oil Pump for Sale

The CYZ pump centrifugal oil pump delivers strong self-priming performance and does not require a foot valve. Before startup, simply charge the pump casing with a specified volume of liquid; once started, it completes priming in a short time, making it well suited to applications involving frequent start/stop cycles or complex operating conditions. Its compact layout, smooth running, low noise, high efficiency, and easy serviceability make it especially suitable for installation in confined marine spaces or mobile setups.

Major wetted components—such as the casing and impeller—are available in high-quality cast aluminum alloy or cast iron for handling non-corrosive liquids. By selecting stainless steel or other corrosion-resistant materials and pairing them with corrosion-resistant mechanical seals (e.g., Viton, PTFE), the pump can be adapted for more aggressive media.

Functionality of the Marine CYZ Centrifugal Oil Pump

1. High-Efficiency Self-Priming: No foot valve or vacuum priming device is required. Prior to startup, only a small amount of priming oil needs to be retained in the pump casing for rapid self-priming (≤1.5 minutes at 5 meters suction lift). This makes the pump ideal for frequent start-stop applications such as tanker stripping and bilge drainage.
2. Corrosion Resistance & Sealing Design: Wetted components are available in cast iron or stainless steel to accommodate media such as gasoline, diesel, seawater, and certain chemical liquids (operating temperature range: -20°C to 140°C). Equipped with a hard alloy mechanical seal and explosion-proof motor, with an optional cooling chamber for high-temperature conditions.
3. Non-Overload Safety Structure: Designed with a back pull-out configuration, allowing pump maintenance without disconnecting the pipeline. The optimized hydraulic design ensures safe operation across the full flow range without the risk of motor overload.

Our CYZ Series Centrifugal Oil Pump Advantages

• Easy Operation: The CYZ self-priming centrifugal oil pump features a foot valve-free design. Only a small amount of priming oil needs to be retained in the pump casing to enable quick and automatic priming, eliminating the need for external vacuum devices. This significantly simplifies operational procedures, reduces system dependency on auxiliary equipment, and minimizes maintenance complexity—ideal for applications involving frequent start-stop operations.
• High Compatibility: Our CYZ centrifugal oil pump offers broad media adaptability, capable of handling fluids ranging from low-temperature diesel at -20°C to high-temperature oils up to 140°C, including gasoline, kerosene, diesel, and aviation fuel. Depending on application needs, wetted components can be made from cast iron, bronze, or stainless steel, providing excellent corrosion resistance and enabling safe, long-term transport of seawater, freshwater, and certain chemical liquids. This makes it suitable for a wide range of marine and industrial scenarios.
• Safe and Reliable: The pump can be equipped with explosion-proof motors, making it suitable for use in hazardous or flammable environments and compliant with marine explosion-proof standards. The hydraulic components are designed with a non-overload feature, ensuring that the motor is protected from overload even at high flow rates or head conditions. A back pull-out design further enhances maintenance efficiency, allowing inspection and servicing without dismantling the piping—ensuring safe and reliable operation in confined or enclosed spaces.
