FCY Series Floating Suction Unit (Floating Outlet Device)

In the petrochemical and energy storage & transportation industries, the sedimentation of moisture and impurities in tank oil is a common problem affecting outbound quality. The FCY Series Floating Suction Unit (also known as Floating Outlet Device) is an efficient and intelligent equipment specially designed to solve this pain point. Through an ingenious mechanical design, it automatically and continuously extracts the cleanest oil from the upper layer of the storage tank, fundamentally improving the quality of the dispatched oil and ensuring the safety of downstream processes. It is a key component for enhancing economic benefits and operational reliability in modern oil storage management.

Core Principle: Intelligent Positioning Based on Buoyancy

One end of the device is fixedly connected to the oil outlet pipe at the bottom of the tank, and the other end is suspended by a float (or floating ball) system. Its core lies in the application of Archimedes' buoyancy principle and lever mechanism. When the liquid level in the tank changes, the buoyancy on the float changes accordingly, driving the entire oil suction arm to rise and fall synchronously. This means that whether the storage tank is in oil intake, storage or oil dispatch operation, the oil suction port of the device can automatically and accurately maintain the optimal position under the liquid surface, always extracting oil from the upper layer.

Since impurities such as water and sediment have a higher density than oil, they naturally settle to the bottom of the tank during static storage. Therefore, the upper oil layer is always the cleanest part in the tank. The FCY device utilizes this natural law to achieve "selecting the best from the best", ensuring that the moisture and solid impurity content in the dispatched oil is significantly reduced.

Core Value for You

Superior Oil Outlet Quality: Directly reduce moisture and mechanical impurities in the dispatched oil, easily meet stricter outbound quality indicators or customer agreement requirements, and enhance corporate reputation and market competitiveness.
Strong Protection for Downstream Equipment: Clean oil is the best "protector" for downstream precision equipment. It can significantly extend the service life of oil transfer pumps, flow meters, precision filters and end-user engines, and greatly reduce failure rates, maintenance costs and unexpected downtime losses caused by impurity wear and corrosion.
Wide Applicability & Reliability: The product series is complete, perfectly suitable for vertical dome-roof tanks, internal floating roof tanks and horizontal storage tanks, and applicable to various media such as gasoline, diesel, kerosene and light fuel oil. Key components such as universal swivel joints adopt patented or mature designs to ensure flexible rotation and long-term leak-free sealing; the main structure material can be selected from carbon steel, 304/316/L stainless steel and aluminum alloy to meet the requirements of different corrosive environments and medium compatibility.
Fully Automatic & Maintenance-Free Operation: The entire working process does not require external power supply or complex automatic control systems, and is completely realized by physical principles. With a sturdy structure and no wearing parts, it can achieve stable operation without manual intervention for a long time after installation, which is safe, energy-saving and labor-saving.
Flexible Customization Services: We deeply understand that each tank project is unique. Therefore, we provide comprehensive customization capabilities — targeted design and manufacturing can be carried out according to your specific tank diameter, height, internal floating roof type (providing Type A without floating roof/Type B with floating roof series), design flow rate (nominal diameter DN100 to DN600, flow rate 80-3000m³/h), and specified flange standards (such as HG, ANSI, DIN, etc.), ensuring perfect integration of the equipment with your system.

Typical Application Scenarios

The device is an ideal choice for improving operational quality in the following scenarios:

Refinery finished oil blending tanks and delivery tanks
National strategic petroleum reserve depots and commercial oil depots
Airport aviation fuel storage tanks
Harbor terminal marine fuel oil (bonded oil) supply tanks
Raw material oil or solvent storage tanks in chemical enterprises
