In industries such as chemicals, pharmaceuticals, and new materials, the tank farm area serves as a critical transfer point connecting raw material supply with workshop processes. Especially for long-distance liquid transfer from storage tanks to workshops, ensuring safety, sealing performance, and stable conveying becomes the core of equipment selection. Magnetic pumps, with their leak-free and explosion-proof structure, have become the preferred solution for transferring raw materials and finished products in tank farm systems.

1. Transfer Scenario: Challenges from the “Tank Area” to the Workshop

A “tank area” refers to the zone for raw material unloading, product loading, and intermediate material storage. In actual operations, liquids are transferred from tank trucks into storage tanks, typically within a distance of around 20 meters. Next, the material must be conveyed stably through pipelines to workshops located more than 50 meters away.

This type of transfer scenario has three typical characteristics:

A. Long distance and high head requirements: Pipeline lengths often exceed 50 meters; head must account for pipeline resistance and elevation differences.

B. Media are usually volatile or toxic: Such as alcohols, ketones, and organic solvents—requiring excellent system sealing.

C. High explosion-proof requirements and limited maintenance access: Usually located in hazardous areas, demanding reliable, low-maintenance equipment.

2. Why Magnetic Pumps Are Suitable for Tank Area Transfer

Shengshi Datang magnetic pumps use magnetic coupling drive and require no mechanical seals, eliminating leakage risks structurally. For toxic, flammable, or volatile media, magnetic pumps offer true zero-leakage performance.

Through optimized flow channels and efficient magnetic drive systems, Shengshi Datang magnetic pumps ensure stable output even during long-distance transfer, making them especially suitable for high-frequency transfers from tank farms to workshops.

3. Key Points for Pump Selection

A. Head Matching: For pipelines exceeding 50 meters, account for frictional and local resistance, as well as tank liquid level and workshop elevation. It is recommended to design the pump head at 1.2× the actual requirement as a safety margin.

B. Material Selection: Wetted parts should be selected according to the medium’s corrosiveness—stainless steel, fluoroplastic lining, or other corrosion-resistant materials.

C. Flow Rate Determination: Select based on unloading or process requirements, generally using the maximum required flow to avoid insufficient feeding or frequent start–stop cycles.

D. Motor Configuration: Use explosion-proof motors, with a grade not lower than EX d IIB T4, matching the operating conditions to ensure long-term safe operation.

E. Cooling Structure: For easily vaporized liquids, choose magnetic pumps with auxiliary cooling circuits to prevent demagnetization of the inner magnet or local cavitation in the pump chamber.

4. Reference Case

At a fine chemical plant in East China, ethanol is transferred from the tank area to a workshop around 55 meters away. Initially, mechanical-seal centrifugal pumps were used, but frequent leakage and long maintenance cycles caused issues. They were later replaced with fluoroplastic-lined magnetic pumps equipped with explosion-proof motors and auxiliary cooling loops. After three years of operation, no leakage occurred, and maintenance costs dropped by more than 40%.

Long-distance transfer from tank areas to workshops demands high levels of stability and sealing from pumps. Magnetic pumps, with their sealless design and strong corrosion resistance, demonstrate significant advantages in such systems. During selection, factors such as transfer distance, medium characteristics, and site explosion-proof requirements should be thoroughly evaluated. Choosing products from manufacturers with extensive industry experience ensures long-term stable operation. Shengshi Datang Pump Industry’s magnetic pumps have been widely used in such applications and are a reliable choice.
